Stay cool on the playground with this insulated flip-up bottle. The insulated bottle will keep your child's drink refreshingly cool all day long. The bottle has a practical flip-up drinking system, easy for even the smallest children to use. Just flip up the spout to drink! The spout is attached to a straw inside the bottle. It's guaranteed leakproof, so the bottle can be stored safely in a school bag, but it also has a handy loop to make it easy to carry. The insulated bottle is also suitable for carbonated drinks. When used for carbonated drinks we recommend to use the bottle without the straw. The bottle is completely BPA-free and easy to clean. To ensure you can enjoy your stainless steel bottle for a long time, we recommend hand wash only. The cap is dishwasher safe.
