This is one of the largest bottles we sell, making it the ideal hydration companion for those long days in the office or a full day on the beach or trail. Stay cool and hydrated all day long, no matter where your adventures take you.

Replacing the existing cap on all our Wide Mouth bottles, the new award-winning Flex Cap is the ideal combination of strength and flexibility.
