Sea to Summit Medium Ultra-Sil Pack Liner
Sea to Summit 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
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.
