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
- When packing your pack, make sure that sharp / very hot objects do not come into contact with the UltraSil fabric.
- When you return from a trip, make sure your UltraSil Pack Liner is completely dry and aired out before being packed for storage
