The Wide Mouth Flex Straw Cap is designed to fit the threading of all Hydro Flask's Wide Mouth bottles, regardless of size. The straw is long enough to reach the bottom of all their Wide Mouth bottles except the 40 oz Lightweight Trail Series Wide Mouth bottle. (If you do use the Flex Straw Cap with the Trail Series 40 oz, the last bit of beverage may not be reachable with the straw, which really, is just a reminder to refill.)
