51 oz - 1445 g Pack

The Flex pack is there when you need it and easily tucked away when you don’t.

The Flex Pack was designed with hunters and boaters in mind. Of course, backpackers enjoy it, too. It’s a highly visible dry bag with a harness built to carry a load in comfort. And, when it’s not in use, it can easily be stored away.

*All closeout items and items in the bargain bin are final sale and cannot be returned.

Size Guide



The Flex Pack is a 50 L dry bag with multiple compression straps that can be used to secure gear outside the pack – think paddles, lifejackets, ski poles, etc.

Now you don’t have to suffer through carrying a load with a pack ill-designed for the job. The Flex Pack uses the same suspension system as our Fusion line of backpacks. That means it’s designed to carry heavy loads without needing a heavy pack. Its unique oval shape and sturdy harness keep the loads closer to your center of gravity, so you don’t have to worry about a shifting pack.

Its simple roll-top design keeps your equipment nice and dry, even in the wettest conditions. It features a release valve that allows you to remove any excess air once the bag is loaded. It has four last points for attaching the bag securely to your boat.
