Hydro Flask 40 oz Wide Mouth Reviews - Trailspace

May 31,2024

A super durable, insulated water bottle that carries 40 fluid ounces (1.18L). When weight is a concern (i.e. long backpacking trips), I don’t take this along, but otherwise, it is with me wherever I go.

Big thirsts deserve big water bottles, and the Hydro Flask Wide Mouth model with the Flex Cap fits the bill. It checks in at 32 oz., and is made from stainless steel with signature TempShield insulation to fend off condensation. No matter the temperature requirements for your drink of choice, the Hydro Flask bottle is up to the task.
