Durable steel, yet as light as a feather! The simply and elegantly designed Stanley AeroLight travel mug is perfect for work commutes or on your office desk. AeroLight is suitable for both hot and cold beverages, and it is remarkably lightweight compared to other mugs of the same size. The secret lies in Stanley's AeroLight technology, which does not compromise on durability or thermal performance. Fill the mug with cold water, warming tea, or morning coffee, and enjoy your drink later at just the right temperature. The double vacuum insulation keeps drinks hot for up to 4 hours and cold for 6 hours. With ice cubes, the drink stays cold even longer! The lid seals tightly, so you can toss the mug in your bag or backpack without the worry of leakage. The cup is also compatible with most car cup holders. A volume of 0.35 l ensures that you can definitely take a sufficiently large cup of coffee with you.
