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.
Features • 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
