Why We Like the 40oz Wide Mouth Water Bottle with Flex Cap 2.0

For an ice cold sip of water on the ready all day long, we fill up Hydro Flask's 40oz Wide Mouth Water Bottle with Flex Cap 2.0. Our thirst quencher stays pure thanks to the zero-flavor transfer property of pro-grade stainless steel, so when we reach the lookout, we can revive our soul with the refreshing straight-from-the-mountain taste of unadulterated H2O. The double-wall vacuum locks in beverage temps, whether we want that crisp sip on a summer hike or a steaming flow of coffee on cold morning commutes.
