Rambler Bottles are built to go wherever there 's a need for ice cold or piping hot beverages. Which we think is pretty much everywhere. The Rambler Bottle offers a wide mouth with Over-the-Nose™ technology for easy loading, drinking, and cleaning. The TripleHaul™ cap is comfortable to grip, 100% leakproof, and insulated. You'll also get all the benefits of a Rambler, including durable 18/8 stainless steel construction and double-wall vacuum insulation that keeps your beverages cold (or hot) while preventing condensation through its No Sweat™ design.
