Fresh look for a fan favourite
From road trips to endless hours at the beach, our 40 oz (1,182 ml) Wide Mouth bottle keeps you well-hydrated from sun up to sun down. We couldn’t think of a bottle more deserving of a makeover, so we’ve elevated the silhouette and simplified the 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 as 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.
