BlockerLite Dry Sack

Whether you're thru-hiking the Pacific Crest or paddling through the Boundary Waters, it helps to have the space-saving, weight-shaving storage of the SealLine BlockerLite Dry Sack. It's a great option for storing your down-filled sleeping bag on the trail or water, seeing any outside moisture compromises its ability to keep you warm and comfy at night.

This dry sack features waterproof fabric, roll-top closure, and welded seams that provide impenetrable protection from outside moisture without adding much weight to your pack. In fact, the BlockerLite Dry Sack weighs only a couple of ounces at most and stores compactly inside your pack with its flat-sided design.
