The new Sea to Summit Ultra-Sil® Dry Sacks are more than 50% lighter than their super popular standard 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
