Take your refreshment with you in this insulated Hydro Flask water bottle, powder-coated for an easy grip that's sweat-free and durable. Thanks to the brand's TempShield double-walled, vacuum-insulated technology, it guards the temperature of your drink, keeping beverages cold up to 24 hours and hot up to 12 hours when using the lid. Made with pro-grade stainless steel, a robust metal known for its resistance and purity, the bottle protects against the transfer of flavours, keeping your water pure-tasting. The durable construction ensures no condensation or heat transfer to the outside of the bottle and it's easy to clean. Both the bottle and its lid are dishwasher safe. This leak-proof design is BPA-free and comes with a Standard Mouth Insulated Leak-Proof Flex Cap for even better temperature control, plus a carry handle for drinking on the go.
