Based on the success of their Compression Dry Sack, Sea to Summit has made a lighter version from 30D Ultra-Sil ®. It retains all the clever functionality of the original design with all the lightweight touches of Ultra-Sil ® technology. The Ultra-Sil ® Compression Dry Sack compresses gear to one-third the volume while keeping it dry.


  • Waterproof seams, double stitched and fully tape sealed
  • Waterproof and air-permeable eVent ® fabric base
  • Hypalon ® closure does not wick moisture
  • Reinforced stitching on all stress points
  • Air compresses out, water can’t get in
  • Roughly half the weight of the original Compression Dry Sack
