Keeping your gear dry on the water is a constant battle.

Tips

For maximum waterproofing, roll the top down at least three times before buckling. To compress the bag and remove excess air, press down on the bag before sealing. When attaching to a boat, use the Hypalon loops with straps or carabiners. For longer portages, add the optional shoulder straps for hands-free carrying. Rinse with fresh water and air dry after saltwater use to prolong the bag's life.
