The Ultra-Sil® Dry Sack is the ideal dry sack for adventurers who need to protect their belongings from wet weather.


  • Ultra-Sil® 30D siliconised high-tenacity CORDURA® nylon fabric for exceptional strength
  • Ultra-Sil® fabric has a 2,000 mm waterhead
  • Non-wicking Hypalon roll-top closure with stiffener at the top for an improved seal
  • Fully seam sealed for water resistance
  • Translucent for easy visibility of contents
  • Slippery finish for easy packing
  • Round base in all sizes

Regarding proper use Sea to Summit advises:

  • 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.
  • Avoid contact with sharp objects or subjecting the sack to high abrasion, as this could compromise the waterproof fabric.
  • 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.
  • Not intended for situations where dry sack will be submerged under water.
