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 and comes standard with the Chug Cap. With a quick twist, the TripleHaul handle comes off, exposing a shatter-resistant, dishwasher safe spout that allows for controlled gulps on the go. When it's time for a wash or refill, remove the entire cap to expose the bottle's wide mouth.
