All of our packs are made to be used in systems. Packs which are waterproof are challenging to get dry if water every gets inside. Our packs are made water resistant with a heavy, coated 1000 denier corudara bag protecting more waterproof bags inside. But if you are tired of cheap, disposable plastic liners getting torn mid-trip, letting in that water you’ve been fighting to keep out, try our re-usable pack liner made from 400 denier nylon. It adds a layer of water resistance to the system that’s long-lasting, easily cleanable, and reusable. Not only does it help keep the gear inside dry, it helps keep the inside of the pack clean. It’s equipped with a cinch top for closing off the contents.
