Ultra-Sil Pack Liners
We also have a “pack liner” made of our amazingly light Ultra-Sil. The shape of the sack is designed to fit the internal contours of a backpack, so the base is oval, rather than round.
- Ultra-Sil Pack Liner opens wide for easy packing when it’s inside a pack
- Unique top closure: extra fabric at the top folds in and velcros in place, then rolls down, creating a more compact closed loop at the top
- Made of PU coated Siliconized Cordura®
- Non-wicking Hypalon™ roll-top closure with stiffener at the top for a better seal
- Fully seam sealed
- Uses low profile buckles
- Slippery finish for easy packing
- Three sizes available to fit different pack volumes
- Comes assorted in three cool new colors: kiwi green, sky blue and orange orange
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.
