Yeti's 18 oz. Rambler® Bottle is a tough, leakproof essential for your daily commutes, hike pack, and the wide variety of mountain town adventures. This bottle is double-wall vacuum insulated to keep your drink cold even when treking in the sun. With a quick twist, the TripleHaul™ handle comes off, exposing Yeti's 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.
