The double-wall Hydro Flask 40 oz Wide Mouth bottle keeps contents cold for 24 hours or hot for up to 12 hours. Constructed of stainless steel, the bottle is BPA-free, rugged and lightweight. The wide mouth makes it easy to fill, empty and clean.
Thanks to patent-pending double-wall construction, the outside of the bottle isn’t affected by the temperature of the contents, so cold beverages won’t cause sweat on the outside of the bottle, and hot liquid won’t cause you to burn your hands. The stainless steel interior also prevents flavors from lingering.
Backed by Hydro Flask's unconditional lifetime warranty, the Hydro Flask 40 oz Wide Mouth bottle is available in your choice of colors.
