Double wall glass mugs keep a hot drink warm for longer while the outer glass stays cool to the touch. The air between the two walls slows cooling and shields your hand, and the clear glass shows off the colour and layers of a latte, tea or iced coffee. This category has 18 double-walled mugs and cups in thermal glass, from 200 ml to 500 ml, almost all from the Wilmax ThermoGlass collection.

Shapes and sizes

• Classic mugs – 250, 300 and 400 ml, 11–13 cm tall, for everyday coffee and tea.
• Tall, slim cups – 200 to 500 ml; the narrow 500 ml cup is 15 cm tall, so the layers of a latte macchiato stay visible.
• Low, wide mugs – 250, 300 and 400 ml at 7–8 cm tall; the wide bowl lets a milky coffee cool to drinking temperature faster.
• Bubble mugs – 250 and 300 ml, with the inner bowl appearing to float inside the outer glass.

Hot and cold drinks, care

The mugs work for hot coffee and tea as well as cold drinks: with ice, the double wall stops the glass misting over. According to the product pages, all of them are dishwasher and microwave safe. They suit the home, the office, cafés and hotel breakfasts.
