The Rambler® 18 oz bottle is a necessary addition to your morning hikes, kayak trips and daily commutes. This tough bottle is double-wall vacuum insulated to keep your water cold until the last sip, dishwasher-safe for easy cleaning and comes standard with the chug cap. The shatter-resistant, dishwasher-safe spout allows for controlled gulps on the move. When it's time for a wash or refill, remove the entire cap. Customize your bottle to really separate it from the pack.
