Boundary Portage Pack

A great option for keeping gear dry, I also love getting off the water and filling it full of wet gear. Super durable material and comfortable straps. Forrest W.
General Manager, Guide & ACA Instructor

The Boundary Portage Pack uses watertight DrySeal™ roll-top closure, along with a heavy-duty, 30-ounce scrim-reinforced vinyl bottom and 19-ounce scrim-reinforced vinyl body. The lightweight suspension system includes waterproof and ventilated shoulder straps, and a waist belt on every size. Available in three sizes: The 115L and 70L sizes close with side-cinch buckles, while the daypack-size 35L includes a top buckle closure.

Removable Suspension
Easily removable lightweight suspension system ideal for moderate loads or heavier ones on short hauls.
DrySeal™ Closure
Updated dual-strip roll-down closure for tight, simple sealing, makes it easier and more intuitive to achieve an optimal seal.
Withstands quick submersion and will float if dropped in the water, suitable for canoe, kayak and rafting use where boats may tip, flip or be swamped.


  • Adjustable padded shoulder straps, sternum strap and webbing waist belt.
  • Side cinch straps add peace of mind and secure compression with big loads.
  • Made of rugged, flexible, and fully waterproof materials designed to withstand frequent and demanding use.
  • Fully welded seams for a stronger and more durably waterproof construction compared to sewn-and-taped seams.
  • Made in U.S.A. of domestic and imported materials.
