Still haven't found a backpacking stuff sack that is ultra-lightweight and waterproof? Look no further than the Sea to Summit Ultra-Sil dry sack.

  • Features

    • Siliconized on the outside, tough Cordura® nylon is weatherproof, lightweight and durable for hiking and backpacking in wet conditions
    • Polyurethane coating on the inside permits the fabric to be seam taped; 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 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
    • Ultra-Sil sacks are designed for use inside a backpack and are not suitable for boating
    • Comes in assorted colors only; sorry, specific color requests cannot be accommodated
    • Field Repair Buckle can be replaced with just a screwdriver

    Imported.
