The Civilian Lab Ghost ring Bottle Holster is a unique, minimal means of carrying a small to medium drink bottle. It's the simple things that are usually the most ingenious. Why carry a canteen or a leaky bottle, when all are bulky, and hard to keep clean? Bring a fresh bottle each time and enjoy the cleaner taste, then simply recycle it. Snap Ghost Ring's metal clip onto the neck of a common plastic drink bottle, clip it to a belt loop, or bag strap, and you've got an instant canteen. Unclip the sidepush buckle - The clip side stays on the bottle while you drink (swivel-hook side stays hooked on you.) Perfect to clip on a climbing harness, or day pack, it is superior to similar products using a rubber ring to hold the bottle as this ring typically breaks within a few days. Civilian Lab`s steel snap is indestructible.
