Manfrotto has introduced four new carry-on trolleys to its Pro Light Reloader collection: the Pro Light Reloader Air-55, Air-50, Pro Light Reloader Switch-55 and Pro Light Reloader Spin-55. The Air-55 and Air-50 are fairly straightforward trolley cases, but both the Switch and Spin have a little more to offer, albeit with a higher price tag.

Pro Light Reloader Air-55

The Pro Light Reloader Air-55 can fit up to two pro-style DSLR, five lenses and a 17" laptop. It features various zippered pockets on the front and side of the bags, as well as a handful of internal pockets for storing accessories. Gear organization is done with the help of large supportive dividers and 19 additional shock-absorbing dividers that can be maneuvered around to fit your needs.

The side of the bag has a dedicated strap system for holding tripods and there's an integrated TSA combination zipper lock. Manfrotto notes the ripstop nylon fabric is water-repellent, but the bag also comes with a rain protector.

The Pro Light Reloader Air-55 is currently available at B&H for $379.99.

Pro Light Reloader Air-50

The Pro Light Reloader Air-50 is identical in design to its Air-55 contemporary, but slightly smaller with fewer zippered pockets and internal dividers. It can hold up to two pro-style DSLRs, four lenses and a 15" laptop.

It too features various zippered pockets inside and out for organizing accessories and comes with two supportive dividers and 12 additional shock-absorbing dividers for making the most of the internal storage space. Manfrotto also includes the integrated TSA lock and accompanying rain protector with the Air-50.

The Pro Light Reloader Air-55 is currently available at B&H for $329.99.

Pro Light Reloader Switch-55

The Pro Light Reloader Switch-55 is similar to the Air-55, but has a little trick up its sleeve. In addition to working as a rolling carry-on case, it can also be turned into a backpack by taking a set of integrated shoulder straps out of its front pocket.

Like the Air-55, the Switch-55 can fit up to two pro-style DSLR, five lenses and a 17" laptop. There are multiple internal and external zippered pockets as well as a side strap for attaching a tripod.

The Switch 55 comes with large supportive dividers and 14 additional shock-absorbing dividers for securing and structuring gear inside the bag. Manfrotto has included the TSA compliant three-digit lock and an accompanying rain cover.

The Pro Light Reloader Switch-55 is currently available at B&H for $389.99.

Pro Light Reloader Spin-55

Last up is the Pro Light Reloader Spin-55. As the name suggests, the Spin-55 features four wheels — instead of the two on the other Pro Light Reloader cases — that give it the ability to spin freely on the ground, whether you're running through the airport or on-location at a shot.

The bag features a polycarbonate shell and a nylon insert that can be removed if needed. It features a front access compartment on the outside of the bag as well as multiple internal zippered pockets for additional accessories.

The Pro Light Reloader Spin-55 can hold two pro-style DSLRs, five lenses and a 15" laptop. It features side and top handles as well as an attachment point for a tripod. An integrated TSA-approved lock is included as is a rain protector for those times when the weather gets a little rough.

The Pro Light Reloader Spin-55 is currently available at B&H for $399.99.
