The Hydro Flask Cooler Cup is two great things in one: it’s a can or bottle cooler, and with one quick switch, it’s a 12 ounce reusable beverage cup. As a small cooler cup, it’s brilliantly versatile with a silicone sleeve that lets you slide in a narrow bottle or a can, all with the same snug fit. Pop off the hydro flask boot and you have a 12 ounce drinking cup made to keep cold drinks cold and hot drinks hot. This BPA-free and phthalate-free cooler cup works with a wide range of bottles and cans, so you'll always be prepared. Whether you're camping with friends, relaxing on a beach, or sailing on a lake, it's the ideal portable cup holder for any event. This Hydro Flask cup product is backed by a manufacturer's lifetime warranty.
