Ultra-Sil® Compression Dry Sacks

Product Description

Based on the success of our Compression Dry Sack, we’ve made a lightweight version from 30D Ultra-Sil®. We retained all the clever functionality of the original compression dry sack, with all the lightweight touches of our Ultra-Sil® technology. The Ultra-Sil® Compression Dry Sack compresses gear to one-third the volume while keeping it dry.



  • 40% lighter than the 70D Compression Dry Sac
  • Ultra-Sil® 30D siliconised high-tenacity Cordura® Nylon 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
