YETI Rambler 18oz Insulated Bottle with Chug Cap - 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 the 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 and DuraCoat finishes. Made with kitchen-grade stainless steel, so they're puncture- and rust-resistant. No sweat design keeps your hands dry and unaffected, no matter how hot or cold the beverage inside. Dishwasher safe
