The Hydro Flask 21oz Standard Mouth Water Bottle might be called a water bottle, but you can use it for all drinks. This stainless steel bottle has a double-vacuum design that keeps hot drinks hot for 12 hours, and cold drinks cold for 24 hours. The standard width top makes it easier to get more hydration, quickly. Hydro Flasks are BPA-free, and they resist bacteria and odor so you taste the drink, not the bottle.
