This little clip couldn't be handier. We keep ours clipped through the swivel part of the strap. Not the bit that goes into the leather! You can securely clip the bottle to the buckle loops at the back of your pants, this keeps the bottle in place behind you while hiking, dancing or riding a bike. Clips your keys on it while you hit the surf. The clip will also go through the same 2 holes the strap does, so you can remove the strap and attach to your belt or loops.
