The Stuff Sack is made from a durable 70D recycled Nylon and is the perfect solution for organised modular packing on any adventure. A white interior coating helps to shed moisture and makes finding your contents easy. The unique tear-proof drawcord top with Capture Cord Lock opening is easy to use. Available in three colours for optimum colour coding and organisation of your gear. These tough Nylon Stuff Sacks do not have taped seams or a roll-top closure; so they are water resistant rather than waterproof.
