We've redefined cool with our new insulated drink bottle. Our newest drink bottle has insulating super powers! The double walled stainless steel keeps liquids cool for up to 8 hours and warm for up to 6, so now your little one can stay hydrated whatever the weather. Complete with carry handle and push button opening, designed specifically for little hands. Clean modern design and big kid aesthetic. Available in six fab b.box colours. Kids love our easy drinking silicone straw top. Parents love no leaks in the bag (when the lid is closed). Replacement straw packs available, sold separately. When using to keep liquids warm - for best performance fill the stainless steel base with hot water for a few minutes to warm it before pouring water out - and filling with warm liquids.
