The whopping 64 oz Rambler Bottle takes insulation to the next level, complete with a double wall vacuum to keep drinks hot or cold for hours. Perfect for remote campsites and rough worksites alike. Just like the other Rambler Bottles, youll find the 64 oz outfitted with a TripleHaul cap, making it easy to grab on the go and even easier to open up when youre ready to wet your whistle. The 64 oz Rambler Bottle also features a No Sweat design to keep condensation from collecting and its 188 stainless steel construction can withstand a serious beating. Unlike narrow mouthed drink bottles that are a hassle to fill or rinse, our Rambler Bottle features Over the Nose technology for easy loading, drinking, and cleaning. And its BPA free. In other words, the Rambler Bottle is the only insulated container for cold or hot beverages thats built for the wild.
