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

• 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
• For tips on washing your UltraSil Pack Liner, please see the ‘care of dry sacks’ section of our
