Sea to Summit Ultra-Sil Pack Cover

- +


The Ultra-Sil Pack Cover ends the debate about whether you should carry one or not. It's a tiny and compelling solution and the medium size weighs less than four ounces. Plus it packs into its own small stuff sack - why wouldn't you carry one?

Product Details
  • 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
