I love this little pack. It's perfect for cycling, day's out and city trips, both with and without an internal camera unit. I'd say this is the most versatile and well used of all my camera packs. It's always in demand for a variety of trips from a lightweight walk in the hills (with a small ICU and a camera body and two lenses), to a flight to visit relatives with a few clothes and essential. On aircraft it passes any carry-on test and fits perfectly under the seat in front, with space for your feet on either side. The bright colours available are also useful for cycling where you need a lightweight, visible and comfortable pack. I often use it when capturing drone footage, cycling from location to location with the small shallow ICU installed. It's not overcomplicated but it is tough and weather resistant with the DuraDiamond fabric. It also weighs virtually nothing so it's 'Air' designation is well deserved! Tue Mar 31 2026 02:31:00 GMT+0000 (Coordinated Universal Time) Victor Bellehumeur Perfect Size I was looking for something small that could accommodate my GFX and three lenses and this fits perfectly. I didn’t want any extra cords, straps, buckles hanging off the bag and I needed light as possible. My solution for gear protection was to use wraps instead of the ICU and they work out best for me. Maximum weight turns out to be 10.7 lbs with the camera, three lenses and some Kase Armour filters. All in all this is a great purchase for me. Time will tell how well it holds up. Wed Oct 01 2025 17:01:05 GMT+0000 (Coordinated Universal Time) amona cofar Mochila RJu This brand is amazing. This time I bought an Rju backpack for our teenage son because he needed one for school. It's very, very comfortable when carrying several things. The materials are, as always, high quality. All I can say is: I 100% recommend FStop. Thu Sep 25 2025 07:46:38 GMT+0000 (Coordinated Universal Time) Carlo Cellerini Meets expectations I needed a backpack for day trips that could hold other things (keys, wallet) in addition to the equipment. Ryu air turned out to be perfect for my needs. Mon Jun 16 2025 06:13:01 GMT+0000 (Coordinated Universal Time) Redelf Janßen Rating: 4/5 Rju AIR | 18L Modular Daypack - Magma (red/orange) Nice small backpack. My only recommendation is: give the backpack an add'l horizontal strap to connect the left and right shoulder straps Mon May 19 2025 10:05:14 GMT+0000 (Coordinated Universal Time) Stuart Langrehr Rju Aiir 18 “ Very good. It’s a pack that’s for me is in the middle. Not too big, not too small, a great day pack and pack for TSA acceptance. I like it and appreciated the inclusion of the internal unit. Recommend…. Tue May 13 2025 23:39:23 GMT+0000 (Coordinated Universal Time) J M Great Small pack for day trips Absolutely recommend this pack for those days out where you don't need all you gear. Small, tidy and inconspicuous it doesn't look like a camera bag at all. I use mine with the medium ICU, but the small would equally be useful. Used it to carry my Fuji XH2, 50-140, 56 & 23, along with extra batteries and strap. Had room to spare too. If you didn't want to take more gear check out my picture for all the gear you can fit. Also, Spring Lake blue is the colour to go for! Tue May 06 2025 12:31:52 GMT+0000 (Coordinated Universal Time) Fabio Jose Silva Luis Perfect gear backpack to use under-sit in air plane I’ve used this backpack to carry my gear on my last est trip to Mexico,man’s it fit everything that I needed to give life to my products, was perfectly to put it under-sit on the airplane. I could fit a mavic air 3s, Sony a74 plus two lenses, plus batteries and filters. Fri Apr 25 2025 16:18:31 GMT+0000 (Coordinated Universal Time) John Wells Nearly perfect If this bag has a water bottle pocket, it would be perfect for this size. Sat Apr 05 2025 12:53:01 GMT+0000 (Coordinated Universal Time) Martina Brodu Perfect for me I used it when I wanted to travel light, for small photographic equipment, my sketchbook and pencils, and documents. Perfect!
