Product Details

  • A Backpacker magazine Editors' Choice Award Winner!
  • Super compact and ultra lightweight
  • Made of Ultra-Sil™ nylon, a polyurethane coated siliconized Cordura® for ultimate waterproofing and maximum durability
  • Non-wicking Hypalon® roll top closure with stiffener at the top for a better seal
  • Soft and flexible with a slippery finish for easy packing
  • Translucent fabric allows good visibility of the contents
  • All seams are double stitched and tape sealed
  • Colors: Orange, Pacific Blue, Kiwi
  • Proper Use: Any roll-top dry sack must be closed properly to ensure water can't get in. Begin by folding the Hypalon™ strip down first and be sure to have at least three rolls before closing the buckle.
  • Avoid contact with sharp objects or subjecting the sack to high abrasion, as this could compromise the waterproof fabric.
  • Ultra-Sil Dry Sacks should only be used to store sensitive electronic devices when used in conjunction with another, heavier-duty dry bag - the double bag method. For maximum protection of electronics the use of a waterproof hard case with a mechanical seal should be considered.
