Just the right size for little hands, our Hydro Flask for kids is made with the same stainless steel and double-wall vacuum insulation as our bigger bottles. Every sip stays icy cold for up to 24 hours—so when recess or practice wraps up, the perfect refreshment is waiting on the sidelines. With a colorful, easy-to-clean Straw Lid and a durable Flex Boot, this is the perfect companion for any adventure—big or small. Our unique double-wall vacuum insulation protects temperature for hours. Cold drinks stay icy cold and hot drinks stay piping hot so you can stay refreshed for any adventure. Made with 18/8 pro-grade stainless steel to ensure pure taste and no flavor transfer - and the durable construction stands up for whatever life brings. Our proprietary powder coat means an easy-grip, sweat-free, and extra-durable bottle that you can take anywhere. Hydro Flask guarantees this Hydro Flask product with a limited lifetime warranty against manufacturer defects.
