Ultralight cover protects pack from the weather 

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? 


  • Made of 30D Ultra-Sil™ fabric constructed from CORDURA® yarns for durable, waterproof performance.
  • This pack cover does not use seam construction to ensure that it is completely waterproof
  • Packaged in its own mini siliconized Nylon stuff sack that remains attached to the cover so it can't get lost
  • Keeper strap (sizes S-L) pulls the pack cover tight across the pack harness
  • Sold in four sizes to fit daypacks up to large backpacks
