Why we picked it
KeepCup builds the Thermal from 18/8 stainless steel with a double vacuum wall, so coffee sits against steel the whole way down. The lid is where plastic comes in. KeepCup names it a PP alloy sipper lid with a silicone gasket, and coffee passes over it with each sip. It comes in 12 oz and 16 oz at barista cup sizes and fits most car cup holders. KeepCup says you can put it in the dishwasher but hand washing keeps the finish longer. It can't go in the microwave. It suits anyone who wants the KeepCup shape with heat retention that the glass Brew can't offer.
