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.

  • 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

Proper Use:

  1. Any roll-top dry sack must be closed properly to ensure water can’t get in. Begin by folding the Hypalon® strip down first and be sure to have at least three rolls before closing the buckle.
  2. Avoid contact with sharp objects or subjecting the sack to high abrasion, as this could compromise the waterproof fabric.
  3. Like all manufacturers of roll-top, fabric dry sacks, Sea to Summit recommends that sensitive electronic devices be ‘double bagged’ (i.e. putting electronics inside one dry sack then placing this inside a second dry sack). For maximum protection, the use of a waterproof hard case should be considered.
  4. Not intended for situations where dry sack will be submerged under water.

NB: While our Drysacks are designed to protect gear from rain and water dunking accidents they cannot guarantee to protect electronic gear when fully submerged. For this we recommend fully rated IPX standard diving protection cases.
