The large Sea to Summit Ultra-Sil pack liner seals the contents of your pack in an ultralight layer of waterproof protection for peace of mind when the weather gets wet. Siliconized on the outside, tough Cordura(R) 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(R) 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.
