I got this bag as an addition to my prvke 31l. The prvke serves as a gear locker for getting everything together to wandr over there and the rogue 9l sling for to wandr while I'm there.
I have a canon r5mkii with 15-35, 24-105, 70-200, and 100-500 lenses. Any 2 lenses fit comfortably in the bag with 1 mounted on the camera body. There is ample room in the pockets to carry the 2 cpl and 2 variable nd filters in the pockets. The sleeve on the bottom will accommodate my aluminum tripod or a thermos style drink container. The laptop space is huge, though I don't tote my laptop around. The zippers are amazing
I find the bag is pretty comfortable for a 2-3 hour photo walk. The bag also keeps the contents dry in a light but steady rain.
