Perfect for morning hikes, afternoon ski lessons, or evenings by the campfire, Hydro Flasks 20 oz Wide Mouth bottle is made with professional-grade stainless steel and a wider opening for faster fill. We couldn’t think of a bottle more deserving of a refresh, so we’ve elevated the silhouette and simplified design without compromising one degree of performance. And our 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.
