The GEMSTONE MUG 0.3L from the Swiss brand Sigg is an isothermal mug that will follow you everywhere.

Compact, this mug is the smallest of the GEMSTONE range. Moreover, its grip has been improved and its weight reduced while keeping its technical qualities. The double wall stainless steel construction will keep your drink hot for 12 hours and your drink cold for 18 hours.

Sigg has also thought about the cleaning of the mug and has provided an easy to use system to remove the cap.
