Sea to Summit came up with a pack liner made of their 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.


  • The Ultra-Sil Pack Liner received the 2006 Editors' Choice award from BACKPACKER Magazine.
  • 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.


Capacity:Small - up to 3,000 cu in (50 L)
Medium - up to 4,300 cu in (70 L)
