The Flex PR+ is a multi-use pack specifically designed for pack rafters
The Flex PR is a 75L dry bag with a removable suspension system designed for carrying heavy loads in comfort. Whether you are portaging on a canoe trip, hunting in the backcountry, or doing trail maintenance, the Flex PR will keep your gear dry, your accessories handy, and your back comfortable.
The Flex Pack PR+ is designed to handle the included 75L dry bag or the popular portage barrels. It has adjustable compression straps to help compress and stabilize any load. Dual removable side pockets are great for water bottles. Stash snacks, a rain jacket, or other gear securely in the zippered large gusseted front stash pocket.
The removable bottom stabilizer straps are perfect for packrafters using portage barrels and help ensure heavy loads ride easily. It even has an eight-inch wide stash pocket running the length of the pocket perfect for stowing a paddle.


Now you don’t have to suffer through carrying a load with a pack ill-designed for the job. The Flex Pack PR+ uses the same suspension system we use on our lightweight packs. That means it’s designed to carry heavy loads without needing a heavy pack. It’s 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.
It’s 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.
With four lashing points, the Flex PR+ stays secure in your boat no matter how gnarly the ride.
