Like all Hydro Flask caps, the Hydro Flip is made out of 100% recyclable PP5 and is BPA-free. The lid features a flip-top opening with rubber stopper to plug the opening and help prevent spills when not in use.
The Hydro Flip lid fits our 18 oz Wide Mouth, 40 oz and 64 oz flasks.
Please note that the Hydro Flip lid does not fit on the older style Wide Mouth flasks.
