In the age of ultra-lightweight everything we have developed a range of ultra-lightweight dry sacks to save those crucial few grams. Using a 15 denier Sil/PU nylon fabric we call Ultra-Sil® Nano, a lightweight side release buckle and a thinner roll top closure we have created a dry sack that is 30% lighter than our standard 30 D Ultra-Sil® Dry Sacks!

  • Ultra-Sil® Nano 15 D nylon fabric for advanced strength to weight performance
  • Ultra-Sil® Nano has a 1,200mm waterhead
  • Fully seam-sealed for maximum water-proofness
  • Reinforced stitching for greater seam strength on all stress points
  • Hypalon® roll top closure does not wick moisture
  • Siliconized fabric with a smooth finish for easy packing
  • Compact and super lightweight
  • Oval base design for easy packing
  • Suitable to keep contents dry in any wet situation where the bag is not submerged
