Avantro travel mugs and coffee carafes feature superior double wall vacuum insulation. Double-wall insulated carafes and mugs keep beverages hotter (or colder) than single-wall mugs. There are 3 different types of double-wall insulation. Some mugs have air between the walls, which helps to hold temperatures for up to an hour. Some have foam insulation between the walls, which acts a little better than air. The best temperature retention is achieved with vacuum insulation: 2 walls of stainless steel from which air has been evacuated, creating a vacuum between the walls. Better quality vacuum insulated mugs keep beverages hot for 3 hours, or cold for 6 hours.

Avantro offers the highest standards of quality. Avantro uses precision equipment and tooling, the best quality stainless steel for vacuum processing, deep drawn parts that result in minimum welds, copper plating, polished interiors and satin finished exteriors, plus 100% testing. Avantro's state-of-the-art vacuum furnace technology produces a consistent "high" vacuum for maximum temperature retention and allows the design of compact, lightweight products.

Plus Avantro adds innovations like Crystal Metallic colors, Leakproof Lids, and Docking Station base on all travel mugs
