6 – Backpacks for hiking and general use: quick FAQs and tips
This is a compendium of the many questions I’ve had on forums, PMs, etc. I’ve tried to be as short and concise as I could.
1 - How exactly do you experienced hikers test a new backpack? How often do you return or exchange it?
a) We buy from a local hiking shop whenever possible. We first try the pack empty, then loaded - we typically bring a current pack with all our gear inside and transfer the stuff. When that’s not possible we use the store’s sand bags, keeping in mind that those small 10 pound bags that sits at the bottom of the pack are too compact to represent a real load. If the store has stairs we do multiple passes up and down those stairs.
b) For all packs referenced in my articles, we spend a minimum of 100 miles (~161 kms) and 10,000 feet (~3000 meters) elevation (up and down mountains) testing a pack with varying loads, terrains and weather. Those who live in flat areas have to be a bit creative to mimic going up and down mountains (a pack feels and behaves very differently on slopes) but there are always buildings or parking garages with lots of stairways so that’s not a problem (never, ever test a backpack on flat terrain only!)
c) I asked our Stats guy to post a survey with your second question. Our community returns or exchanges a little over 20% of purchased packs. This percentage should logically be much higher for folks with less experience.
2 - How do I measure my torso length?
You can’t do that correctly by yourself but it’s easy with a friend. Lean against a wall and have your helper make two horizontal marks with chalk or masking tape: one at your iliac crest (the top of your hip bone) and one at your C7 vertebrae (that’s the big protrusion at the base of your neck, easy to find when you lean forward a bit.) The distance between these two is your torso length.
Or, ask your hiking shop to measure this for you.
Or, do both to be on the safe side (some hiking shop staffers are poorly trained for this.)
Reminder! It is your torso length that actually matters for backpacks, not how tall or short you are. My own torso length, for example, is the same as that of many friends who are several inches taller than me (yes, this means that the short-legged creature with an ugly mug you saw out there could well be me!)
3 - What would be a simple way to describe the difference between a Pressure Panel pack and a Tensioned Mesh Panel pack?
The best analogy I’ve ever heard came from one of our members, a witty guy who says to newbies:
“You have 2 vehicles in front of you: my new Volkswagen ID4 SUV with its modern suspension and Air Conditioning, which would be any topnotch TMP pack, and then you have my old Yugo with its horrible seats, back-breaking suspension and of course no AC, which would be pretty much any PP photo pack. Now, which vehicle do you think would be best for your backside?”
This analogy is a bit simplistic, I know, but it’s accurate. Now, take into account that photo pack makers often make you pay 2-3 times more for the Yugo than for the VW and you understand why more and more people buy TMP packs, even for short city walks or zoo strolls. And with temperatures rising quickly just about everywhere, more and more folks in places like Alaska or Norway also use TMP packs. It’s simply a smart buying decision based on solid, common sense.
4 - One of my favorite things about hiking is listening to the many sounds of nature as I explore woods and mountains. I just bought a great big TMP backpack which I love but the loose straps constantly make those flapping sounds that drive me crazy. Is there any way I can mitigate that?
Better yet, you can completely eliminate the problem. Here are the two main solutions we use:
1) Buy a couple spools of high-quality sewing elastic band (3/4” for shoulder and side straps, 1” to 1 1/4” for belt strap) and stitch/sew short sleeves out of those. You want the sleeve to wrap around its strap loosely enough that you can slip at least 2 layers under it when you have to double or triple fold the strap end (common with hikers who have a small waist.)
2) Buy high-quality rolls of double-sided hook-and-loop (these have dozens of uses, buy Velcro Onewrap or similar, don’t waste your money on the cheap stuff) and make your own strap bands. Here are the directions for a standard belt strap: grab the end of your roll and wrap it around the strap with the hook (prickly) side against the belt (this will ensure a better hold), cut the sleeve with sharp scissors. Done!
Note to all manufacturers (except Decathlon, see Post 4): these DYI solutions are not an excuse for you to be so unprofessional as to “forget” to fit all strap ends on your packs with sleeves (an industry expert told us that the mass-production cost of a strap sleeve is under one penny…)
5 - Pack A is lighter than pack B, will it work better for me?
Not necessarily. In fact the opposite is often true. The pack’s own “dry” weight is not important and you can’t really tell it anyway, as we have verified countless times through blind tests. We actually make a game out of it and it’s quite revealing to see that even very experienced hikers “guess wrong” more than half the time about which pack a friend has strapped them in, while fitted with blinders (eyes covered with a neck warmer or a scarf.) What actually matters is a pack’s weight distribution abilities (just like actual back ventilation.)
6 - Should a man never purchase a woman backpack model or vice versa?
While it’s important for the customer to be offered a wide diversity of packs, we would not recommend that you exclusively base your purchase on “gender” models. The most important thing is that you actually try the pack on, loaded with all your gear (FAQ 10.) For example, two of my own daypacks are “female” versions and they work great even though I have fairly broad shoulders. We also have many ladies in the group who love hiking with “men” models that are a good fit for them.
7 – I shoot a lot of skiddish wildlife. What packs do you folks use for long and heavy rigs and how do you get those in and out of the bag?
Here are the inside measurements (collar raised and then slightly cinched for obvious reasons) for the packs we use the most with long combos:
DFP40: 18" to the bottom divider, 24" to the actual bottom with divider unzipped (the DFP44EL is about 3” longer)
DFV60: 22" to the bottom divider, 29" to the actual bottom with divider unzipped
The new CP44 works well too with up to 27" to the actual bottom with divider unzipped.
Method 1: some of us place our long rigs facing up inside the pack. This makes it easier to keep the lens hood on and results in less chances of damaging the rig if you ever drop the pack hard or fall backwards. Access is through the top for very long rigs or via the front panel for shorter ones.
Method 2: others prefer their rig facing down, slide the lens inside a plastic or cardboard tube that is a bit wider than the lens and/or hood (look for such tubes at your hardware or art supplies store.) The cam body rests on the top rim of the tube (some add a foam or rubber gasket,) making the rig super easy to pull and drop in. They fill the pack around the tube with clothes or food which are still easy to access if needed via the front panel. Filling the side bellows pockets with gear also helps to keep the tube centered. Here cam access is through the top only.
8 - Won’t a TMP pack “pull me backward” or make me more tired?
Such concerns are more misconceptions and internet lore than anything. Why? A well-fitted and correctly loaded TMP pack spreads your load evenly and close to your spine by design - the heavier the load, the closest it actually gets to your CG (Center of Gravity.) How certain are we? My community has logged countless thousands of hours hiking, trail running and mountain biking with TMP packs for over two decades, so you’d think we would have noticed by now if this was a problem, wouldn’t you?
Ironically we have found that the opposite is often true. First, given that a great many PP packs are deeper than TMP packs, they “pull you back” more because their own CG is further away from yours - except of course for highly-specialized climbing packs that are narrow, shallow and tight against the spine. And second, all good TMP panels spread the pack’s weight evenly which is absolutely not the case with PP packs (hence the heat, pain and discomfort they generate.)
9 - Do all of you guys always use an ICU with the TMP backpacks?
No, the majority uses the DFP40 or the Vario, both of which have many practical options to stash bodies and lenses, which makes an ICU unnecessary (those side bellow pockets are awesome!) Some just wrap their gear in socks, clothing layers, neoprene pouches, etc. Some use a shoulder or holster bag as a portable ICU. Some of us occasionally add an ICU when we need more than 4-5 MFT lenses (or 2-3 DSLR lenses) on specific shoots, in which case the bottom compartments are great for quick access.
10 - I have an ICU model X by brand Y, will it fit pack Z? How? Can you post photos of your setups?
Our community now comprises well over one thousand hikers, out of which around 300 own one or more packs and ICUs, which means hundreds of possible combinations. If I posted pics of one, I would have to share pics of the others or many readers would immediately jump to the conclusion that brand/model A is better than brand/model B, etc. Not helpful, plus I would not get permission to post others’ pictures anyway since we have a very strict covenant about sharing our photos, which we only do within a strictly private network.
But back to your core question, it’s not a complicated problem if you go about it in a sensible way.
If you start from scratch, always buy the pack first since it is by far the more important part of the hike/photo/video equation. Once you find a pack that fits your needs, get one or more ICUs that fit it, keeping in mind that bringing too much gear, such as a laptop, tablet or too many lenses on a short hike, is a very common mistake. Do not fall into that trap!
Getting the right ICU in-store is easy, just bring your pack and all your gear (photo and else) and check what fits inside what. When you order an ICU online, measure its outside dimensions and compare them to the inside dimensions of the pack (be aware that manufacturers don’t always publish correct dimensions.) In fairness, that is of course a bit more difficult with TMP packs since they tend to use fairly sophisticated, “non-square” designs, as opposed to PP photo packs that often are a simple rectangular box (basically a large, quality ICU with shoulder straps and pockets.)
– What we usually prefer for top-loading packs is an ICU with side opening that is about 3/4 inch (2cms) smaller than the smallest dimension of the pack at the top opening (under the lid) which means that this side opening now faces up – you should be able to run your index finger around the insert. Since good TMP packs have by design a slightly curved frame, it’s good practice to first load “the other stuff” that will sit below the ICU: food, clothes, stove, water, extra shoes, etc. Then insert the ICU. It may get a little squeezed halfway down if things are on the tight side, but that’s okay because that is exactly where we want it (remember that the pack’s curve flattens as the load increases which makes the contents slide down a little): you now have quick top pack access via the side opening of the ICU for an easy grab of your most-used cam+lens combo.
Tip: just like testing an empty pack is close to useless, never test an ICU by just sliding it into the top of an empty bag since that is not representative at all of what you will experience on the trail.
– With packs that are also panel loaders, those of us who prefer to place their photo gear at the bottom of the pack use of course “standard” ICUs with the top panel that unzips for gear access.
If you buy online, make sure the vendor has a free or fair return policy and don’t hesitate to try more than one ICU. Fitting a load inside a backpack always involves trial and error, so don’t behave like an armchair hiker! Buy the stuff, get out there and test it yourself. How? See FAQ #1.
Tip: check your old camcorder or film shoulder bags (or buy on CL or ebay) as some of those fit just great inside backpacks and are far better built than most ICUs.
11 - I figure that my photo and other gear (without water) occupy a volume of about 28 liters for my 1-2 day hikes during the warm season. I hesitate between a 30L and a 40L TMP backpacks. The 40L is about one pound heavier. Which one would you recommend?
The 40 liters is your only sensible choice. Think this through… With a 30 liters plus water for just one day, you are already maxed out. With the right pack you could lash extra stuff to the outside of the pack, but it’s not always practical, or even safe if you bushwhack. In reality, the 40L may well be too small for a 2 day hike in winter since cold season clothing and gear take up far more volume.
What about that extra pound for the larger empty bag? As we have verified countless times, blind tests with empty TMP packs reveal that it is not possible, even for experienced hikers like us, to know for certain if we have a 45-60L or a 25L pack on our back. Bottom line? When in doubt the wise thing to do is always to buy the larger model. Remember that reducing a large TMP pack down to half its volume or even less is incredibly simple and easy (just grab those compression straps and give them a good little tug!) Conversely, expanding the volume of a small pack is anywhere from difficult to downright impossible since most of them have few or no lash points.
12 – How do I avoid getting dirt on my pack when setting it down in some deep muddy mess?
Use any of these old hiking tricks:
1) With a top-loading pack, simply wrap the bottom of the pack in the rain cover, set it down in the mud, open the top and access whatever you need.
2) With a front panel loader, place the rain cover on the harness side and set the pack down. You now have clean and dry access to the contents.
3) Unfold half of your sleeping bag pad (super easy with Z-types, my favorites) and sit the pack on it.
4) Same with that extra trash bag you always carry (you do, don’t you?)
5) Or simply unfold about half of your ground sheet (Polycryo or Tyvek 1443R are great, avoid standard tarps or plastic sheets.)
Note: Still agonizing over getting some dirt on any of the above? Consider dirtless activities such as knitting or crossword puzzles.
13 – My TMP backpack is super comfy but it squeaks like hell and that drives me nuts! Can I fix that noise with WD40?
We are all-too-familiar with this issue. One of our members tried WD40, it didn’t solve the problem and made his pack stink so bad that he had to trash it. Powders such as talcum or graphite need to be reapplied frequently and only work on simplistic, very visible frames such as the ones found on some UL packs.
Here is what works and how. Get a syringe with a strong needle which you fill with either liquid silicone or castor oil. Now examine your pack closely to find where the frame is. This can be quite difficult since that TMP frame is often tightly encased in fabric (and rubs against it, which creates the “squeaking like a hellish little animal” noise you hear on every step.) Now poke a small hole into the fabric and inject some lubricant every inch or so. Be aware that silicone is highly “runny” so you’ll want to use very small amounts of it. Finally, gently “massage” the frame with the pack upside down for optimal spread. This method completely eliminates the squeaks. Those of us who hike a lot with their Osprey packs need to do this 2 to 3 times a year, but it brings your joy of hiking back and it’s totally worth the time.
14 – Lately I’ve seen more “roll-top” photo backpacks on the market. What do you think about those?
Well, this is yet another idiotic fad exploited by unscrupulous manufacturers who take advantage of inexperienced, geeky, gullible customers.
But first, a bit of history;.many thru-hikers - aka long distance hikers, those who set challenges for themselves such as hiking thru the entire AT (Appalachian Trail) or the PCT (Pacific Coast Trail) in the USA, or shorter but often more challenging trails in Europe such as the glorious GTA (Grande Traversée des Alpes) - rejoiced when the outdoors industry came up with super strong, super light tarp-like, theoretically waterproof fabrics such as Dyneema or Xpac. These were first used for roll-top dry sacks but a few clever people realized that hey, if you just added straps to one side of that big pouch, you had a backpack! That started a whole cottage industry of highly-specialized, small UL (Ultra Light) pack makers who cater to the needs of thru-hikers (https://www.garagegrowngear.com is a good source.) Personally, I think that’s just great. However, what works for a thru-hiker is not what works for many hikers or photographers, far from it:
1) These light and tough fabrics are hard to piece together, requiring highly-specialized stitching and/or taping techniques, which is why these packs almost never use zippers. This is the real reason for the rolltop system, a mechanism that is fairly waterproof when new. But after a while the thin fabric tends to break down at the top where it is constantly folded and unfolded, letting water in.
2) Even on smaller packs, the lid (aka “brain” in some hiking circles) is a critical feature since it gives you quick, convenient access to all sorts of essentials: first aid kit, keys, wallet, sunglasses, compact cam, binoculars, sunscreen, etc. (add rain gear, gloves, extra lenses etc. on larger packs.) Where do you put all that stuff in a rolltop bag? Well, you have no lid, so you ain’t got no choice but to just dump them in the main compartment, which becomes a big messy affair, which explains why many of these roll-tops have very large front and side pockets usually made of some wide netting type of material, which in turn totally defeats the stated claim of using waterproof material for the pack since all the stuff stashed in those outside pockets gets soaked when it rains.
3) Those large outside mesh pockets, even the ones made of “tough” netting, simply are too weak off-trail – thru-hikers often bushwhack, either by choice or because they got lost - which results in mesh torn from branches, rocks or thorns. Such had happened to a good friend of mine whom I had joined for a few days on his thru-hike. He also owns a DFP60 but he had decided to use his Osprey Exos 58 for that adventure, on the count that it is a couple of pounds lighter. When I caught up with him, 25 days into his thru-hike, he was still happy with the Exos’ very good TMP, harness and numerous lash points, but he was starting to get really frustrated with the lack of hip belt pockets and rain cover, the flimsy side compression straps with their bad zigzag routing (one strap has already failed) and the large tears in the mesh outer pocket which had become almost unusable, forcing him to restock foods twice as often. I had brought strong tape which allowed him to make temporary repairs, but just a week later he arranged for his wife to meet at a crossroads where she brought his Vario. He later told me that this pack swap had made the rest of his journey far more enjoyable.
4) On a standard pack with an extensible collar 100% of the added height is usable. For example, the DFV60 truly adds 10 liters of capacity. With rolltops you often loose at least half of the height and capacity once the top has been rolled down and clipped in. Worse, packing is more difficult because the upper part of the remaining space is slanted. Opening/closing rolltops is also much slower than lids.
15 – Do you guys have tips about rain covers? I’d like to get a good one!
a) Look for one that has a loose fit (for example, a 50 liter cover for your 30 liter pack, this way you can leave things like water bottles, tripods or extra cams/lenses in the outside pockets) and that is of the far superior variety that has a strap and buckle at mid-back – amazingly, no main manufacturer, except REI on a few packs (Post 4) offers this common-sense feature. Just slide the strap behind the TMP and buckle it. This ensures that the cover cannot rip out in strong winds or while bushwhacking. It also makes it impossible for a thief to snatch it off.
Tip: If your cover doesn’t come with a drain hole, always punch one (1/4 or 3/8 inch) about 2 inches from the back edge of the cover’s bottom as it’s normal for rain water to sneak down there. Make sure to add a brass or aluminum grommet (revolving hole cutters are junk, look instead for a quality grommet kit, the good ones usually come with a hardwood block.)
b) I personally have 2 covers of different colors for each of my main packs: a bright color when visibility is key to survival (hunting season, way off-trail hikes) and a black or dark gray one when I want to be as inconspicuous as possible, be it in nature (wildlife approach, BIF, etc.) or in crowded areas such as risky cities, train stations, etc. (in those places I only use my pocket cam in a hipbelt pocket and/or my bridge cam clipped to my chest, covered by my mesh vest when I’m not shooting. I also keep money and important documents in a hidden pocket underneath my shirt.)
16 - I’m a female hiker and I absolutely hate how the ends of those long belt straps flap against my bare thighs in the Summer. Can I just cut them off? The store told me to tie them into knots but I hate those even more because they rub against my stomach.
I understand your frustration but the problem with this idea is that hiking with extra layers in colder weather easily adds 6 to 8 inches to your waist. So if you cut off the loose straps, your pack will be unusable in cold season. Make your own strap sleeves instead (see how in FAQ 4.)
17 – I bought an expensive hiking umbrella but it just doesn’t do the job. The way it ties onto a shoulder strap in front and a pole loop in back gives it an angle that gives me some protection from the rain, but almost never enough from the sun. Help!
A few of our members have skin conditions that require a high level of UV protection and these types of umbrellas were of no help. So, one of them invented a brilliant “Humbrella” system that actually works far better for sun and rain/wind protection. This works with all Deuter Futuras and many other TMP packs. Here is the DIY he said I could share here:
1 – slide a piece of PVC tubing (1/2 or 5/8 inch usually works) behind your TMP, just outside one of the shoulder strap anchors, all the way to the bottom.
2 – cut it about 2” above where the load adjuster strap is stitched into the frame.
3 – add a strong hose clamp (to prevent it from ever sliding down) near the top and cinch the area just below the clamp to the base of the load adjuster with paracord of a zip tie.
4 – cinch the bottom of the tube to the lower part of the TMP or frame with paracord of a zip tie (on the Futura 26 you can just wedge it in there.)
5 – buy whatever quality umbrella you like and remove the handle to expose the entire shaft, then cut the J section (end of shaft) off.
6 – just slide the umbrella’s shaft into the tube and you have a Humbrella! Our friends also wrapped the shaft with grip tape in order to have just enough friction for up/down adjustments depending on the sun’s angle.
18 - Could I use a TMP pack as a carry-on? Any other travel tips?
We do this all the time. We also often use some of the smaller TMP daypacks (Post 5) as “personal item.”
Tip 1: when compressed vertically and with the lid empty, the DFP40 and CP44 are only 22” tall and the DFV60 24”, which many airlines accept in-cabin. They rarely measure anyway and the trick is to make them perceive your pack as not-too-big. To do this (after security and before I enter the check-in line) I put my pack down and I fold the hip belt against the TMP. I then compress the entire pack tightly using a 2 inch luggage strap centered vertically (I run it inside the top carry handle.) Now I still have use of the shoulder straps and I still have the same (reasonable) amount of stuff inside my pack, but it looks much smaller.
Note: by tightening the luggage strap even more you can easily make the pack 2” shorter.
Tip 2: I never go to an airport without a lightweight, zillion-pockets vest. Whenever an overzealous airline staffer makes me check my carry-on, I open it up and transfer all my valuable gear, including cams, lenses or a laptop, into those pockets – taking my Texas time which makes the jerk look like even more of a fool than he already is.
Tip 3: Never ever simply check a large backpack if you care about what’s inside. Wrap it inside a large trash bag and secure with straps, or place it inside a cheap-looking, large roller.
Tip 4: The TMP Osprey Farpoint Trek packs are currently best-in-class as multi-purpose travel packs.
Tip 5: Never believe such meaningless claims as “meets FAA (or IATA) size regulations.” The check-in supervisor, or sometimes the Captain, actually decides what is allowed inside the cabin.
19 - Some manufacturers show a “maximum recommended load” on their web site, others don’t. Does this mean that they have not even tested their own backpacks?!
It very well could. Or, that they are simply too lazy and sloppy to provide the info to their potential customers (very common in the outdoors industry.) You don’t say what models you are looking at, but we have found is that packs from the main brands can often handle far more than what they list. Here are concrete examples:
a) A few years ago, on a steep hike with a few friends toward a staffed "refuge" (also called hut, shelter, etc.) in the Alps, we heard a jovial warning and two young guys zoomed by us at what seemed like supersonic speed, in spite of carrying obviously huge loads. One was using one of those big packs used by sherpas around the world, and the other one had a DFV60 with additional bags strapped to the top, bottom and sides (the whole assemblage was so huge that we could barely see his knees!)
A couple of hours later we arrived at the refuge, exhausted, and we got to meet these guys. They were super friendly and we learned that they were making money on the side hauling up supplies twice a week from the village in the valley, deep below. We asked them how much weight they were hauling and they told us usually around 50 kilos each (about 110 pounds, well over twice what Deuter suggests.) Since their packs had been emptied we asked if we could have a look at the DFV60 (my buddy had just bought one.) We looked for ripped straps, busted threads, fabric tears, etc. and found... none. The next morning we watched our two compadres reload their packs with non-compostable stuff and take off running down the steep trail, a simply stunning sight. The refuge staffer explained to us that they in fact used those hauling trips as additional training sessions as... members of their national ski team (these incredibly humble athletes hadn't said a word about that.) Anyhow, this encounters remains a fond hiking memory.
b) The CP44 recently handled a 58 pounds load (~26 kilos) with ease in test mode: large ICU with 1 body (APSC), 10 lenses and 1 TC, small ICU (1 APSC body + 4 lenses), food (inside orange dry box), one water bottle plus tripod in right pocket, two water bottles in left pocket (134 oz water total), jacket plus second tripod lashed to lid, alternate shoes in front pocket, monopod lashed to poles loops. Not visible on this quick snapshot are the big laptop inside its sleeve, a compact cam in a hip pocket, some clothing in the upper compartment, a G1X3, first-aid kit and small items in the lid, etc.

20 – I hiked a lot in my youth but I am currently recovering from a life-threatening medical condition. Could I use hiking to get healthy again? Do you have any advice that could help?
I have been in a very similar situation myself and hiking was indeed a huge part of my own recovery, welcome to the club! Here are a few awesome tips I was given at the time (I have used them ever since):
1) Always “ramp up” very incrementally. Start by walking around your neighborhood for half an hour and add 5 minutes a day until you are comfortable with a 3 hour walk. Then you can gently hit the trail (but always listen to what your body tells you.)
2) Develop your own set of gentle stretches and use those every couple of hours, or every time you take a break (food, pics, nap, etc.) and definitely at the end of your hike.
3) Unless you go on a very short hike, always use at least two pairs of shoes. Personally I swap shoes after roughly 5 hours. I also systematically vary between zero-drop (Altra) and low-drop (Topo, Hoka) shoes. This actually changes your stance and gait and it makes a surprisingly big difference for the rest of the day.
4) For about 5 minutes every hour, grab your load lifters, bring them up and push forward hard at a 45 degree angle (the top of the shoulder straps should lift by about 1 inch) while thrusting your pelvis forward by engaging your core muscles, and keep walking, just a bit slower. This actually changes your posture and also makes a big difference. This is why packs should have real load lifters, such as the ones offered by Decathlon (Post 4.).
5) Keep your hydration level high, even in wet or cold weather.
6) If you do not already own an Inversion Table, buy one (PM me for best current model) and use it every time you come home from a hike, and for that matter, every day. These things last for life and have a myriad of health benefits.
Happy walks, hikes, runs and travels!
