Aladdin Adventurer Dual Use
Price: £24.99 Retained temp (deg C): 77
Why is it called the Dual Use? Simple: due to its particularly wide 75mm aperture, this flask can store drink or food. As a neat practical touch, the jointed handle folds flat for tidy storage. However, neither of the two cups has a handle, and the steel one got so warm, it was virtually impossible to hold. A relatively poor result in the heat-retention test and high price didn't help its cause.
