The Ultimate Direction (UD) Replacement Kicker Cap restores high-performance to your UD water bottle (sold separately). The Replacement Kicker Cap has an off-center that provides ergonomic access. The welded silicone valve is surprisingly durable and opens easily with either your fingers or your teeth. Once it is in an open position, either bite the valve or squeeze the bottle for a smooth, gulp-friendly draw rate. Nudge the valve to the side and it slips back into its leakproof position.
