The Lightweight Dry Sack is a versatile dry sack that is soft and pliable, and ideal for many uses. Made from a lightweight 70D waterproof, durable nylon fabric, its interior polyurethane coating is colored white to improve visibility and make it easy to find small items in low light. Lightweight Dry sacks are available in five colors to optimize color-coded organized packing. They use the same hypalon non-wicking roll-top closure as our other dry sacks and feature a D-ring attachment point at the buckle.
