Dry Sack Ultra-Sil Sea to Summit

Dry Sack Ultra-Sil Sea to Summit is an ideal way to keep your gear dry. The new Sea to Summit Ultra-Sil® Dry Sacks are more than 50% lighter than our super popular Dry Sacks. They’re made of Siliconized Cordura®, which is one of the lightest and toughest waterproof nylon fabrics available. Now you don’t have to choose between keeping your gear dry and keeping it light.

Ultra-Sil® fabric has a 2,000mm 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

Use: backpackers, cycling touring, travellers

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.

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.
