This little travel cup keeps my coffee hot and my ice water ice cold. What more could a girl ask for? The Klean Kanteen delivers your beverage at the perfect temp PLUS the insulation keeps the exterior dry and room temp so you don’t singe your fingers on a piping hot coffee or freeze them if it’s carrying ice. Worth every penny. We have several and a kids water bottle version that go where we go, always a trusty companion sitting in the cupholder.
