The Hydro Flask 40 oz Travel Tumbler is the brand's most-versatile large-capacity tumbler — insulated 40 oz construction designed for the hydrate-more, refill-less use case where capacity matters as much as portability.
The insulated Hydro Flask 40 oz Travel Tumbler cup is here to hydrate more and refill less. The insulation keeps drinks cold for hours, and the durable handle makes it easy to take along anywhere. The 32 oz size stainless steel tumbler bottle can go anywhere, even fitting most cupholders. Cold stays cold, and the flexible straw is easy to sip any which way.
