Description
Double-walled 18/8 stainless with a vacuum gap and a copper-shielded inner wall. We measured it ourselves at 18 hours above 60 °C and 26 hours below 8 °C in a 20 °C room, which is a boring way to say it works. Nothing that touches your drink is plastic or painted — the cap seal is food-grade silicone and the threads are steel — so it does not pick up the taste of yesterday’s coffee. The exterior is bead-blasted rather than powder-coated, so the scratches it collects look like use rather than damage.
