Lightweight, well balanced, comfortable, aero (can't believe I'm bringing this up about a backpack), waterproof, and perfectly functional. Most roll-top bags I've used in the past kept my items entirely dry, but they always came with the inherent wings sitting just behind the tops of my shoulders. Hooking on branches or small trees, scooping up headwinds like two large pterodactyl arms, and leaving me constantly uneasy of my immediate surroundings. In short, they've rivaled the feeling of my niece hanging off my back like a small chimpanzee at a family event.
I've always believed that form should follow function, if form is ever considered in a product. With that in mind, it's easy to see why I've kept an eye on Mission Workshop and their MTB division that is ACRE Supply. Living in such a wet climate means that there's lots of criteria that a bag needs to meet in order to work properly in our conditions.
Coming in a 10L or 14L size, I opted for the latter to ensure that I'd be able to fit all the normal camera equipment I lug around. There's multiple ways to fasten the top flap, which is perfect for those days you may need to tote around an extra lunch, or spare camera body. A large tool-roll housed within the main exterior pocket is perfect for those spare tubes, film, memory cards and any other small accessories you don't want bouncing around aimlessly inside the pack.
One of my favourite features of this bag is it's adjustability. Since receiving this from ACRE I've used it for a number of different activities both on and off the bike, which it managed perfectly. The multiple lower mounting points make it extremely customizable for different body types, or even the same body, during different uses. When hiking I've found the lower eyelets to be more appropriate, but when cycling, the upper eyelets sit in a more comfortable position for my waist while in the saddle. Something I never would have thought of, but am thankful someone did.
