Following the magnificent (and somewhat epic) "BEST BACKPACK / RUCKSACK FOR HIKING PHOTOGRAPHERS (2021)"[1] thread, being noted as (quote):
For starters, a bit more than a month ago, I bought two of these packs for (my wife and) me - a 20 liter "S" frame size version, and 40 liter "L" frame size one (so basically the smallest and the biggest one available).
"Decathlon" makes a generic difference according to one`s height, classifying them as "S" < 170cm (5'7") >= "L" - but it`s your torso length that matters, not your height, so trying one in person (if not measuring your torso as well) is highly advised.
Backpack sizes/weights are listed as:
20L: (H) 60cm x (W) 30cm x (D) 20cm, 1100g (S) or 1270g (L)
30L: (H) 63cm x (W) 30cm x (D) 23cm, 1200g (S) or 1300g (L)
40L: (H) 66cm x (W) 30cm x (D) 26cm, 1260g (S) or 1390g (L)
Measured, "S" frame alone is 45cm tall (measuring the tensioned mesh, not the frame curve), "L" frame is 50cm (being almost exact torso lengths of my wife and me). Frame width is 30cm for both sizes, where the mesh is about 2-3cm away from the back of the pack (when empty).
Load-lifter straps are attached at the top of the frame, while shoulder straps are attached 6cm lower (at 39cm and 44cmm from the bottom, for "S" and "L" sizes respectively). Shoulder straps are 6cm wide, and good 1.5cm thick.
At the lower back, hip-belt is 14cm tall for "S" and 16cm tall for "L" frame pack, putting its center at some 7cm (S) or 8cm (L) from the bottom of the pack frame, and some 32cm (S) or 36cm (L) from where the shoulder straps are attached (and 38cm (S) or 42cm (L) from the top of the frame, where the load-lifters are).
Hip-belt fins are roughly 65cm (S) or 71cm (L) in total length (wrapping around one`s hips), being 1.5cm thick and 10-11cm tall, with large, top-zippered mesh pockets extending some 1-2cm more, and easily stretchable even further. Zippers are about 17cm long, and easy to open/close single-handedly.
I plan on writing down my own experience, use-cases, configurations and observations, using the packs for hikes (or simple walks) where photography (photo-equipment) is involved, but I`ll end up the opening post here, making some general but not easily found knowledge (measurements) already available, also allowing others to share their own findings - or ask questions - in the meantime.
To conclude, here are the exact backpacks I`m talking about (links, but photos, too, in case links get repointed in the future), and a YouTube video screenshot best showing the size difference when fully packed (when empty, all packs are pretty much collapsible to frame size alone, no matter the volume).

..., not to fill that original one with pack-specific posts (causing it to reach its post limit and become practically closed for any further, more general discussion), this thread should serve the purpose of sharing our experiences and answering questions in regards to Decathlon Quechua MH500 (2020) backpack(s) alone.Chris 222 said:The clear standout for us as hiking photographers is the 2020 Decathlon Quechua MH500 30L, a quality TMP pack with outstanding features, a 10-year warranty, dual gear access, good comfort and plenty of nice touches such as strap sleeves, real load lifters, large belt pockets , etc. for a measly 55 euros (roughly $65, less than you spend right now on a car fill-up or a restaurant outing in many countries. I am told that this outstanding value is possible because Decathlon allows no middleman, controls their own manufacturing and distribution, and practices fair profit margins.) Bottom line? The outstanding Decathlon Quechua MH500 30L outperforms all others and is currently the world’s best value in daypacks (closely followed by the MH500 40L, same pack, just a little more spacious at 15 euros more.) If you live in any of the 50+ countries where Decathlon has stores, getting this pack is a total no-brainer.
