Saving crucial grams, the Sea to Summit Ultra-Sil Nano Dry Sack is an ultra-lightweight and waterproof backpacking stuff sack.
● Using a polyurethane coated, 15-denier siliconized nylon, fabric is waterproof, lightweight and durable for hiking and backpacking in wet conditions
● Polyurethane coating on the inside offers the ultimate in waterproofness; seams are reinforced for strength and factory-taped for weatherproof protection
● Hypalon® watertight roll-top closure keeps contents secure and protected; fold the Hypalon strip down first and make at least 3 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
