Which one should you buy?

The Thermos Stainless King 470ml is the flask most Australian commuters should default to: a twist-and-pour stopper, an insulated steel serving cup, and published figures of 12 hours hot and 24 hours cold. Spend up on the Stanley Classic Legendary if you want a flask backed by a lifetime warranty against manufacturing defects, or drop to the THERMOcafe Slimline 500ml, the lowest-priced pick here, if you want the Thermos five year warranty without the flagship price.
