Stay hydrated on-the-go with this stainless steel insulated water bottle by Hydro Flask. Equipped with a flex straw lid that’s leakproof when closed, this stainless steel water bottle features a cup-holder compatible silhouette with double-wall vacuum insulation that keeps your drinks cold for up to 24 hours. 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.
