Outdoor Research Lightweight Pack Cover

The Lightweight Pack Cover by Outdoor Research is made of fabric that's 20% lighter than its predecessor with a waterproof coating. It's seam taped to prevent moisture from seeping through on long, wet days on the trail. An elastic drawcord around the edge creates a tight seal around a pack of any shape and you can pack it down and store it in the built in stuff sack when the weather calms down.
