The Hydro Flask 20 Oz. Wide Mouth Bottle is perfect for morning hikes, afternoon ski lessons, or evenings by the campfire. The 20 oz Wide Mouth bottle is made with professional-grade stainless steel and a wider opening for faster fill. Hydro Flask has elevated the silhouette and simplified the design without compromising one degree of performance. Additionally, this bottle has a Color Last powder coat that is dishwasher safe for even more convenience. Cold stays ice cold for 24 hours, and hot stays wickedly hot for 12, just like always.
