Sea to Summit Ultra-Sil Dry Sack - 6.5 x 18

Still haven't found a backpacking stuff sack that is ultra-lightweight and waterproof? Look no further than the Ultra-Sil. Siliconized on the outside, tough Cordura® nylon is weatherproof, lightweight and durable for hiking and backpacking in wet conditions. Polyurethane coating on the inside offers the ultimate in waterproofness; waterproof seams are double-stitched and factory-taped for added weather protection. Hypalon® watertight roll-top closure keeps contents secure and protected; fold the Hypalon strip down first and make at least three rolls before closing the buckle. Roll-top fabric sacks are not intended for complete submersion; sensitive electronic devices should be double-bagged or packed in a waterproof hard case for maximum protection. Comes in assorted colors only; sorry, specific color requests cannot be accommodated.
