Durable stainless steel, yet light as a feather! Simply and stylishly designed, the Stanley AeroLight travel mug is perfect for your daily commute or on your office desk. The AeroLight is suitable for both hot and cold beverages and is surprisingly 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. Coffee or tea stays hot, and cold drinks remain refreshing for hours. The lid closes tightly, so you can safely toss the mug into your bag or backpack without the risk of leaking. The cup is also compatible with most car cup holders. This model has a volume of 470 milliliters, so it can provide coffee for a friend if needed.
