Robust steel, yet light as a feather. The simple and elegantly designed Stanley AeroLight thermo mug is perfect for commuting or on your desk. AeroLight is suitable for both hot and cold drinks and is surprisingly light compared to similar sized thermo mugs. The secret lies in Stanley's AeroLight technology, which doesn't skimp on durability or thermal performance. Coffee or tea stays hot and cold drinks stay fresh for hours. The lid closes tightly, so you can throw the mug in your bag or rucksack without worrying about leakage. The cup is also compatible with most car cup holders. This model has a capacity of 470 millilitres, so you can also offer a friend a coffee if necessary.
