The Lightweight Dry Sack is our most versatile dry sack. It is flexible in both senses of the word - soft and pliable - and ideal for many different applications. It is made of lightweight, waterproof and durable 70D nylon fabric. The inner polyurethane coating is white to improve visibility and make it easier to locate small items in low light conditions. The Lightweight Dry Sacks are available in five colors, optimizing color-coded packing. They feature the same Hypalon roll closure as our other dry bags and are fitted with a D-ring on the buckle. Ideal for backpacking, biking, travel, ski touring and other adventures.
