This hydration innovation marries our chug-style cap with the simplicity, function, and power of magnets for a 100% leakproof, on-the-go solution. The MagDock Cap is smartly designed with a magnet docking station so you never lose your cap when you're downing your H20. And the customer-favorite narrow spout of our chug cap allows for faster drinking while keeping ice cubes at bay. That's too many wins to count.
