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.

Size Guide

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.

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.

Versatile Affordable pack

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.
