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

X-Small: Fits a 15 to 30-liter pack
Small: Fits a 30 to 50-liter pack
Medium: Fits a 50 to 70-liter pack
Large: Fits a 70 to 95-liter pack

Pro Tip:If you stow any gear externally on your pack, we would recommend buying an Ultra-Sil Pack Cover a size larger than normal.
