Well-suited for morning hikes, afternoon ski lessons, or evenings by the campfire, the Hydro Flask 20oz Wide Mouth - Flex Cap bottle is made with professional-grade stainless steel and a wider opening for faster fill. 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 their 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.
