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. With a quick twist, the TripleHaul™ handle comes off, exposing our shatter-resistant, dishwasher safe spout that allows for controlled gulps on the go.
