This Stainless Steel Sippy Spout Bottle is great for little ones who are transitioning from the bottle and learning how to drink from a cup. Freshness and safety go hand in hand, and that’s why this sippy spout bottle features Thermos™ vacuum insulation technology to keep drinks cold for 12 hours (1 hour limit for milk). The bottle has easy-to-grip contoured handles that are specifically made for tiny hands. The sippy spout bottle is, of course, BPA-free and, by keeping beverages cold, helps resist harmful bacteria growth. Not for use with hot liquids.
