Fresh look for a fan favorite.

From road trips to endless hours at the beach, our 40 oz Wide Mouth bottle keeps you well-hydrated from sun up to sun down. 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.
