Will it fit my bottle?
The Hydro Flip lid fits newer 18 oz Wide Mouth, 32 oz, 40 oz and 64 oz flasks. Please note that the Hydro Flip lid does not fit on the older style Wide Mouth flasks. The newer style wide mouths have an expanded flange just under the neck of the bottle while the older style does not. Also the older style bottles came with a flat cap that has a 2 5/16 in. inner diameter on the attachment loop, while the newer ones have a 2 9/16 inch inner diameter on the attachment loop.
