Double wall vacuum insulation is what does the work here. It slows heat moving in or out, so a cold drink stays cold for up to 24 hours and a hot one stays hot for up to 12, and the outside never sweats or burns your hand. The body is 18/8 stainless inside and out, so it will not rust or hold the taste of yesterday's coffee, and the cap is stainless with a silicone seal, which means nothing plastic ever touches what you are drinking.
