Completely waterproof protection for your pack that compresses into a tiny stuff sack and deploys quickly when you need it most. We recommend purchasing the larger size if you’re on the fence. For instance if you have a 75 liter pack we recommend you purchase the Extra Large instead of the Large. If your pack is under 30 liters take a look at our High Visibility Raincover.Ultralight Raincover Extra Large - Fits 75-110 liter packsUltralight Raincover Large - Fits 50-75 liter packsUltralight Raincover Medium - Fits 30-50 liter packsFeatures Full wrap around cinch with secure hip belt and harness attachment Packs into its own carrying case Fits 50 - 75 liter packs Specs WEIGHT: 0.2 LBS FABRIC: MAIN: 40D Nylon Ripstop ACCENT: 40D Nylon Ripstop BOTTOM: 40D Nylon Ripstop
