The Hydro Flask 32 Oz. Wide Mouth Bottle is big enough for a whole day on the river or trails. The 32 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 design without compromising one degree of performance. 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.
