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 packsFeaturesFull wrap around cinch with secure hip belt and harness attachmentPacks into its own carrying caseFits 30 - 50 liter packsSpecs VOLUMEDIMENSIONSWEIGHTMD0 IN3 / 0 L0H X 0W X 0D IN.0.18 LBS.FabricMAIN - 40D Nylon RipstopACCENT - 40D Nylon RipstopBOTTOM - 40D Nylon Ripstop WARNING: This product can expose you to chemicals including dimethylformamide, which is known to the State of California to cause cancer.
