Durable silicone construction: Made from flexible, resilient silicone for longlasting performance and dependable hydration under regular use. Comfortable, soft bite design: The pliable mouthpiece requires minimal pressure to open, giving a smooth, gentle sip that reduces jaw fatigue during long activities.

Simple replacement and fit: Swap in the valve quickly—remove the old valve and push the replacement sheath onto the existing tubing. No cutting or tubing modification required. Maintains consistent flow and control: Elastic silicone returns to shape for reliable opening and closing, keeping water flow predictable and easy to manage. Broad compatibility: Designed for use with standard hydrationpack drink tubes and mouthpieces so it integrates with your existing setup without extra parts.
