The Rambler® 532 ml / 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. When it's time for a wash or refill, remove the entire cap to expose the bottle's wide mouth. Separate your Rambler from the herd with your choice of stainless, DuraCoat Color and Seasonal finishes.
