Hydro Flask Everest Blue 18 oz. Water Bottle Narrow Mouth

The 18oz insulated water bottle is one of the original Hydro Flasks produced, and continues to be a popular water bottle today. The smaller mouth size means great pouring control and less spills, and the smaller volume makes it easy for stowing in your bag, purse or elsewhere.

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.

Hydro Flask is proud that the all our products are BPA-free, 100% recyclable and are backed by a lifetime warranty.
