With a lightweight, efficient design, this 32 oz water bottle from Hydro Flask features double-walled insulation that keeps beverages cold for 24 hours and hot for 12 hours. Powder-coated stainless steel provides a durable design and clean taste, every time. Wide mouth is easy to drink from, whether you’re on the trail or in the gym. Based in Bend, Oregon, Hydro Flask is inspired by their locale, with a philosophy born from a love of hiking that innovated their signature design - an insulated plastic-alternative metal bottle that's lightweight and efficient for drinks as hot or cold as they were when you first brewed them up.
