Big enough for a whole day on the river or trails, the Hydro Flask 32oz Wide Mouth Bottle - Flex Cap 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.
