The Flex PR+ is a multi-use pack specifically designed for pack rafters
58.6 oz - 1660 g Pack
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.
Overview
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.
Design
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.

- BMBen M.Rated 5 out of 5 stars1 year agoSuper versatile pack transforms into what you need it to be
I just wrapped up an 8 week bikepacking trip where this pack once again proved its versatility. We had to cross some rivers raging from snow melt, so I strapped the empty bike to the pack to keep the entire bike out of the water and my hands free, then held on to trekking poles to shimmy across the river with 4 points of contact on the river gravels. Worked so well I portaged everyone's bikes across.
On that same trip when the single-track got technical on the downhill or the uphill became super steep I simply strapped my bike bags to the pack to lighten the bike and make it more agile and easier to push. No need to repack my bike bags. I never did bring the dry bag specific for the pack.
Previously I have used this pack for bushwhacking through rain forests, mixed pack-rafting down rivers and over land, and trekking across arctic tundra and alpine. The pack works well everywhere.
This pack is NOT for everyone however! If you only want to fill a bag with your stuff, this is not it. For each scenario, it takes extra time and thought to adjust the abundance of buckles.

I purchased this pack to replace my 10 year old Gregory Baltoro 70. I wanted a pack that I could use to haul meat when backcountry hunting, but was also light enough to use for backpacking with the family. The new version with water bottle holders and expanded pockets is almost perfect. My only complaint is that the 50L version is only available in bright yellow, which is not ideal for hunting. I opted for the 75L version in gray instead, but that means I have a lot of extra bag to roll down when not in full 7+ day expedition mode, and I will probably get a second dry bag like the 40L Load Cell dry bag from Stone Glacier for day trips up to weeklong backpacking adventures.
