The RTIC Outback Bottle is constructed with double-wall vacuum insulation that will keep your drinks cold for 24 hours and hot for 6. With a ceramic-lined interior, enjoy the true taste of your favorite drinks without flavor transfer. The flip-top closure lid is both insulated and leakproof when closed and includes a built-in carry ring for travel. Easily add in ice through the wide mouth opening and comfortably hold your bottle while you drink with the UV-protected sweat-free exterior. The built-in silicone coaster creates a soft landing on any surface.
