Featherweight 20-denier silicone- and polyurethane-coated nylon delivers waterproof protection while barely tipping the scales.
PVC-free materials offer a reduced environmental impact over vinyl materials.
Roll-top closure features a grippy stiffening strip to ensure a wrinkle-free, secure seal when closing the dry sack.
Available in 4 colors and 5 sizes, making it easy to organize by both dry sack color and size.
