ACCESS YOUR RAMBLER® BOTTLE ON THE GO WITHOUT MISPLACING YOUR CAP. 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 Mag Dock™ 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. The Mag Dock™ Cap is compatible with many Rambler® Bottles. Please note: Do not use with Rambler® Jr. 12 oz. Kids Bottle or Rambler® 46 oz. Bottle.
