  • Using a polyurethane coated, 30-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
  • Trimming weight, Sea to Summit uses a lightweight side release buckle and a thinner roll top closure
  • 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
  • Comes in assorted colors only; sorry, specific color requests cannot be accommodated

    I carried this bag on my AT thru hike and loved it- the window made it the perfect foodbag! I never experienced the ripping that others have reported, even holding 7 days worth of food, but the waterproofing is not perfect. Hanging overnight in a downpour kept everything dry enough, but after about 3 days straight of rain it would start to get a little damp. I still liked it enough to go back and replace it with the exact same one when my first was stolen, though!
  • DO NOT PURCHASE!!!!

    First used the Ultra-Sil View Drysack in 4L while on a 5 day section hike of the Appalachian Trail in 2010. It was perfect for carrying a number of small items. When I wanted something, I didn't have to dump the drysack out and fish around, but instead simply look through the window to find that extra pair of socks, etc. Extremely light and durable for its weight, I'd recommend it for day hiking, backpacking, extended trips, etc. Not designed for paddling or in a situation with constant abrasion. Very happy with overall construction and fit/finish. Still using the same drysack today with no issues.
