Hydro Flask Double Wall Vacuum Insulated Stainless Steel Water Bottle/Travel Coffee Mug, Wide Mouth with BPA Free Hydro Flip Cap DESIGN IN MIND: With it's easy-access wide mouth, the sleek design holds the same volume of liquid as other leading coffee thermos brands. Also, safety is top-of-mind, as the bottles are made out of non-toxic BPA-free plastics & 18/8 food-grade stainless steel. SLIP-FREE GRIP: Unlike other leading coffee thermoses, Hydro Flask has a powder coat, which gives you a solid grip. The Powder Coat works with the premium TempShield insulation, which prevents condensation from forming on the outside of the bottle, to give you exactly what you want in an everyday refreshment delivery system. JUST THE RIGHT SIZE: Meets your everyday hydration needs in one container, all while keeping it piping hot or ice cold and fitting comfortable and conveniently in your hand or your vehicles' cup holders. The 12 oz size fits under most single cup coffee brewing systems, and the 16 oz and 20 oz coffee flasks are the same size as most standard to-go coffee sizes, so you don't have to use another paper cup. INSULATION INNOVATION: The double-walled, vacuum insulated TempShield Insulation, the same technology used in all Hydro Flask products, will ensure that your beverage of choice maintains its temperature for many hours to come. Hot drinks up to 6 hours, and cold drinks up to 24 hours. EASY ACCESS HYDRO FLIP: Whether youre on the trail or the chair lift, our Hydro Flip Lid makes it easy to sip lattes and hot chocolate on the go. Please note that the Hydro Flip Lid is not leakproof.
