Contigo Streeterville 40oz Insulated Tumbler

The Contigo Streeterville is a 40oz stainless-steel tumbler with double-wall vacuum insulation engineered to keep cold drinks iced for up to 29 hours. It features a leak-proof Autoseal lid with a flip-straw design, made from 18/8 stainless steel with a durable powder-coat finish in Inkycap (dark charcoal). The tumbler fits standard car cup holders and is hand-wash recommended to preserve the seal.

Who it's for: everyday commuters and casual users seeking reliable ice retention at a mid-range price point. Contigo is known for leak-proof engineering; this model delivers solid all-day performance without the premium price of Yeti or Stanley. The tumbler handles daily use well, though some users report occasional lid sensitivity if overtightened.
