This 18oz insulated water bottle is one of the original and most popular Hydro Flasks. It has a smaller mouth size for better pouring control and less spills, and the smaller volume makes it easy to stow in your bag and carry around.
The 18oz insulated water bottle is designed to keep cold liquids chilled for up to 24 hours and hot liquids hot for up to 12.
The double wall 18/8 stainless steel means no condensation buildup on the outside of the bottle and the non-porous, rounded corners on the inner layer help to eliminate bacteria buildup and odors.
All Hydro Flask products are BPA-free, 100% recyclable and are backed by a lifetime warranty.
