The Ultra-Sil Pack Liner keeps the entire contents of your pack dry. Ideal for use in situations where a pack cover may be impractical (for instance where a cover may snag on undergrowth, or for external frame packs where a cover may not fit over the pack). The pack liners are shaped to fit the internal contours of a backpack, so the base is oval, rather than round, and the liner has an overall tapered shape.

  • Ultra-Sil pack liner opens wide for easy packing when its 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 siliconised Cordura
  • Non-wicking Hypalon roll-top closure with stiffener at the top for a better seal
  • Fully seam sealed
  • Uses low profile buckles and slippery finish for easy packing
