The RTIC 64 oz Road Trip Tumbler is built for all-day hydration, all-day cold, and all-day great taste. The ceramic-lined interior protects beverages against metallic taste and smell—even when your water sits in it all day long without a refill. Plus, the durable, double-walled vacuum insulation locks in the cold for up to 24 hours so you'll be refreshed 'til the last sip.
