The Ultra-Sil® pack cover forever ends the debate about whether you can afford the extra weight of a pack cover - the medium size weighs less than 4 ounces and packs into a tiny stuff sack.


  • Made of 30D Diamond Ripstop silicone impregnated Cordura®, so its waterproof finish can't peel or wear off over time
  • Siliconized Cordura® is about one third the weight of traditional coated nylon
  • This pack cover uses a "no seam" construction for complete waterproofness
  • Has a mid-back keeper strap that helps secure it to the pack and keep the sides from catching wind (except size XS)
  • Comes packaged in its own mini siliconized nylon stuff sack that remains attached to the cover so it can't get lost
  • Comes in four sizes to fit daypacks up to large backpacks
