Seal Line: Black Canyon Boundary Pack

Ideal for canoeing and canyoneering, the best-selling portage pack, the Seal Line Black Canyon Boundary Pack features a watertight Dry Seal roll-top closure and is built with heavy-duty PVC to protect your gear in any condition. Now with an improved suspension system, breathable, waterproof shoulder straps and a built-in waist belt, the Black Canyon Boundary Pack comes complete with side-cinch buckles (70L) or top buckle closure (35L).

• Dry Seal Closure: Made with continuous double sealing strips, our roll-top closure is more waterproof than any other. Instructions are embossed directly on the strips, making it easy to get a reliable seal. Simply fold the top of the bag downward between the strips, squish out any trapped air, fold a couple more times, then buckle.
