A comfortable way to carry your gear along on any adventure. Big River Dry Backpacks are reliable, abrasion resistant, and waterproof. From the white water to alpine motor bike trails, this backpack keeps everything dry, together, and safe. A white interior laminate makes it simple to find your gear, while the oval shape and lash loops allow secure stacking or attachment to equipment. The hypalon non-wicking roll-top closure keeps water out, and the Field Repair Buckles can be replaced in seconds with just a Phillips screwdriver. So gear up, roll down and get after it.
