ON-HAND HYDRATION FOR MORNING HIKES, KAYAK TRIPS, AND DAILY COMMUTES. 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 go. When it’s time for a wash or refill, remove the entire cap.
