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.

TempShield™
Our unique double wall vacuum insulation protects temperature for hours. Cold drinks stay icy cold and hot drinks stay piping hot so you can stay refreshed for any adventure.
