Kids Water Bottle--- This water bottle contains a misting device that sprays water at the push of a button to help keep your child cool after a workout! The bottle design is optimised to fit your bike cage, backpack pocket or cup holder. Perfect for the gym, yoga, runners, football, hiking, cycling, travel and camping. Cooling Function--- Bump on the bottle increases the space for cold air circulation and reduces heat transfer. The centre is aluminium foil, which reflects the sun's heat and Extends water cooling time by 50%. Design--- The pull-top drinking spout has a silicone cap that is dustproof and leak-proof. It also has a spray button lock to prevent accidental touching of the spray button when the spray is not needed. Lightweight and with a portable handle for easy hydration on the go. The mouth of the bottle is wide enough to fit ice cubes and is also easy to clean. Safe and Healthy--- The bottle is divided into three layers, the interior is made of BPA-free food-grade PE, the middle layer is aluminium foil and the surface is polypropylene. Lightweight, environmentally durable and squeezable, odourless and beneficial to your daily drinking water health. Please note--- Because of the curved bottle body and the air bump design, in order to achieve the cooling effect, the inner aluminum foil bag will have wrinkles, which is a normal phenomenon.
