The new Sea to Summit Ultra-Sil™ Dry Sacks are more than 50% lighter than the super popular Dry Sacks. They’re made of Siliconized Cordura®, which is one of the lightest and toughest waterproof nylon fabrics available. Now you don’t have to choose between keeping your gear dry and keeping it light.

  • Super compact and ultra lightweight
  • Made of Ultra-Sil™ nylon, a polyurethane coated Siliconized Cordura® for ultimate waterproofing and maximum durability
  • Watertight, 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
  • Nearly transparent allowing good visibility of the contents
  • All seams are double stitched and tape sealed
  • Smaller sizes have flat bottoms, others are round
  • Colors: kiwi green, sky blue and orange orange
Proper Use:
  • Any roll-top dry sack must be closed properly to ensure water canÂ’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.
  • Like all manufacturers of roll-top, fabric dry sacks, Sea to Summit recommends that sensitive electronic devices be ‘double baggedÂ’ (i.e. putting electronics inside one dry sack then placing this inside a second dry sack). For maximum protection, the use of a waterproof hard case should be considered.
