The Rambler 18 oz. The bottle is a necessary addition to your morning hikes, kayak trips and daily trips. This sturdy bottle is vacuum-insulated with a double wall to keep your water cold until the last sip, goes to the dishwasher for easy cleaning and comes standard with the Chug cap. With a quick twist, the TripleHaul handle comes off, exposing our shatterproof and dishwasher safe spout which allows controlled sips on the go. When washing or refilling, remove the entire cap to expose the wide mouth of the bottle. Separate your Rambler from the herd with your choice of stainless steel, DuraCoat and seasonal finishes. Learn more about product use and safety and the dosages and harms of Rambler bottles on our FAQ page. Coated with an advanced oleophobic coating (which is science for: it is resistant to fingerprints), tested to the highest level of UV resistance, and as dishwasher safe, durable and insulated as its predecessors.
