We created our Klean Kanteen Wide 64oz water bottle for one simple reason: we wanted a huge, half gallon full stainless steel bottle for transporting and storing water and other favorite beverages. A favorite for backpackers and outdoor lovers due to it's large size, lightweight single wall construction and wide mouth. The wide mouth fits most backcountry water filters for clean and safe water anywhere. Included Loop Cap has a stainless steel base so your favorite beverage never touches plastic. Compatible with all Klean Kanteen wide mouth caps including our leak proof Café Cap 2.0 when you need a drink through function. Need something insulated? Buy our Insulated 64oz here.
