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. You can also put the MagDock Cap on any of our Rambler Bottles – it’s compatible with all of ‘em. That’s just too many wins to count. The MagDock Cap is not intended for use with carbonated, perishable, or hot beverages.
