The Lightweight Pack Cover by Outdoor Research. These pack covers are made of a lightweight HydroLite fabric with a waterproof coating. The seams are taped to prevent moisture from seeping through on long, wet trail days. An elastic drawcord around the edge creates a tight seal around a pack of any shape. You can pack it down and store it in the built-in stuff sack when the weather dies down.
So sorry, but only 4 items are allowed for comparison, so we're comparing the first 4. I blame the gnomes and so should you.
