The Stanley Quencher H2.0 FlowState is a 40 oz insulated stainless steel tumbler with a handle and a straw lid. It keeps drinks cold for hours and fits most car cup holders, which is why it became the default large everyday tumbler. Its rivals, such as the Yeti Rambler 30 oz and the Owala tumbler, are smaller or lack the handle-and-straw combination. Owners praise the ice retention and the handle; critics say it is heavy when full, can leak through the straw opening, and does not fit every cup holder.
