Hydro Flask 40 oz Wide Mouth Insulated Water Bottle
From epic road trips to endless hours at the beach, our 40 oz Wide Mouth Bottle keeps you hydrated from sun up to sun down. This version is equipped with our Wide Mouth Straw Lid for easy sipping. TempShield™ double wall insulation makes sure your water stays ice cold or piping hot, no matter what it’s doing outside. And thanks to the larger 40 oz size, you can keep the adventure going longer, which means more car karaoke and more beachfront belly flops, all with fewer pit stops to refill your bottle.
