Sea to Summit Ultra-Sil eVent Compression Dry Sack

Size: XS


Following the success of the Sea to Summit Compression Dry Sack, they’ve made a lightweight version from 30D Ultra-Sil®. It retains all the clever functionality of the original compression dry sack, 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.


  • Ultra-Sil® 30D siliconised high-tenacity CORDURA® tylon fabric for exceptional strength.
  • Ultra-Sil® fabric has a 2,000mm waterhead.
  • 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 cannot get in.
  • 40% lighter than the 70D Compression Dry Sack.
