Sea to Summit Ultra Sil 13L Dry Sacks
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.

- All seams are double stitched and tape sealed
- Smaller sizes have flat bottoms, others are round

Proper Use:
- 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.
