Big enough for a whole day on the river or trails, Hydro Flasks 32 oz Wide Mouth Bottle is made with professional-grade stainless steel and a wider opening for faster fill. They couldnt think of a bottle more deserving of a refresh, so theyve elevated the silhouette and simplified design without compromising one degree of performance. And the 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.
