When you need to compress volume without significantly adding weight, the Ultra-Sil™ Compression Sack is an excellent solution. Made from a 30D diamond rip-stop siliconized CORDURA® fabric 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.

  • Thirty-denier diamond ripstop Cordura® fabric is siliconized for water resistance and offers a smooth finish for easy packing
  • Four extra-long straps provide even compression and allow sack to be used to maximum capacity
  • Flip-top lid prevents tangled straps; pull handle on bottom aids in unpacking
  • Quality construction and durable, bar-tacked reinforced stress points hold up to years of heavy use
