The Hydro Flask 64 oz Wide Mouth bottle makes sure there’s more than enough refreshment to go around. Hydro Flask couldn’t think of a bottle more deserving of a refresh, so they’ve elevated the silhouette and simplified design without compromising one degree of performance. And Hydro Flask's Color Last powder coat is dishwasher safe for even more convenience. Cold stays ice cold for 24 hours, and hot stays wickedly hot for 12 — just like always.
