We've brought the legendary insulating power of our Rambler tumblers into bottle form. The Rambler bottle is a next-level insulated bottle, complete with double-wall vacuum insulation to keep drinks hot or cold for hours. The No Sweat design and leak-proof insulated cap keep condensation from collecting. The TripleHaul cap makes it easy to grab on-the-go and open up when you're ready to wet your whistle. The 18/8 stainless steel construction stands up to even the toughest of conditions. And unlike narrow-mouthed drink bottles that are a hassle to fill or rinse, the Rambler bottle features Over-the-Nose technology for easy loading, drinking, and cleaning. In other words, the Rambler bottle is the only insulated container for cold (or hot!) beverages that's built for the wild.
