Transporting fresh, crisp, clean tasting beverages is of tantamount importance to any expedition, whether trailblazing through dense jungles, bashing across arid desert terrain or commuting across town. These rugged containers are constructed with a 100% 18/8 food-grade stainless steel design, providing ultimate protection that’s totally free of BPA and other toxins and won’t retain or impart any funky flavors to your beverage of choice. Topping the extra-wide mouth opening is a sturdy polypropylene loop-cap, with a stainless interior. The wide opening makes filling and pouring a cinch, and universal thread design accommodates a water purifier, without the need for adapters. Resilient, reusable, recyclable and easy to clean - every time. Possibly the last beverage bottle you’ll ever need. The rougher the ride, the better the beverage will taste…now, what to fill it with… 18 oz. (7.5”x2.75”), 27 oz. (10”x2.75”), 40 oz. (10”x3.5”).
