12 oz., Height w/ lid 4.76in, Diameter 2.87in. Move beyond stainless steel for a pure, uncontaminated drinking experience. 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. Hyper Pure Ceramics is the new standard of pure thermal performance.
