Space-saving, ultra-lightweight gear storage for organized packing


When you need to compress volume without significantly adding weight, the Ultra-Sil Compression Sack is an excellent solution. Made from a water-resistant, bluesign® approved Ultra-Sil 30D nylon fabric with Non-PFC DWR this compression sack is far tougher than its weight would suggest. Ideal for use inside your pack or travel bag when you need to compress clothing or bulky soft items to allow space for other essentials or fun holiday items.


  • Compress soft contents down by as much as two thirds
  • Side-release buckle compression straps for fast and easy access
  • Water-resistant, bluesign® APPROVED Ultra-Sil 30D Nylon fabric with a non-PFC DWR finish 
  • Three ultralight compression straps with two ladderlock and one side-release buckles allows easy access and reduces weight
  • Attached flip-top lid prevents straps tangling


BEST USE: Pack Organization

WATERPROOF? The fabric is waterproof enough for storage inside a pack, but the seams are not tape sealed, and the top does not utilize a roll-top closure. So - water resistant rather than waterproof
