Our Kid's Water Bottle Set gives you two 100% leakproof options, with our 12oz Kids' Classic Insulated bottle and our lightweight, non-insulated 18oz Classic bottle. Both come with the Flip Seal Sport Cap that opens and closes with just a flick of the thumb and can be used with or without the included stainless steel straw. Made with certified 90% post-consumer recycled 18/8 stainless steel, featuring our chip-resistant, durable Klean Coat finish. These kid-friendly, narrow profile bottles are made for easier gripping, packing and carrying.
