Coffee should taste like coffee. With this cup, does will. Thermal insulated structure. Ceramic inert. This travel cup keeps your drink hot (or cold) for longer, while not affecting the flavor. Welcome to your new favorite cup. Inspired by the use of ultra-lightweight ceramic insulation in NASA space shuttles, M² Labs has employed new technology to bond a feather-light, inert ceramic to a nearly unbreakable ultra insulative structure, resulting in the patent-pending, Ceramic Clad Thermal Protection System. S.A.I. has partnered with M² Labs to integrate this technology into a historic line of rugged, on-the-move insulative drink wares. The Sojourner Cup includes a removable splash guard and fits perfectly in most cup holders. Volume: 9.5 fluid oz.
