Insulated Stainless Steel AutoSpout Straw Water Bottle keeps drinks cold for up to 14 hours thanks to Thermalock vacuum insulation. Kids will get a kick out of pressing a button to open the pop-up straw for effortless one-handed drinking, and they can easily push the spout under the cover to protect the mouthpiece from the elements. Adults appreciate that the straw features a spill-proof valve so car seats and tables are safe from spills, even if little ones hold the bottle upside down. When it's time to clean up, you'll be happy to know that the lid is top-rack dishwasher-safe and easily disassembles for full-access cleaning. The lid has been designed to eliminate all nooks and crannies in which dirt and grime might accumulate. Just be sure to hand-wash the bottle's stainless steel body. Suitable for ages 3 and up. 100% BPA-free.
