Resmed Airfit F30 headgear

Before the "one size fits all", did Resmed make headgear for the Airfit F30 in a size small? I am a large boned female but short, and the "one size fits all" is too tall for my head. I have to add a third strap in back to connect the top strap with the bottom strap to narrow the distance between the two, but I'd rather have headgear that actually fit in the first place. I've seen postings for the headgear in medium and large, so am thinking that at one time, they must have made it in a small. Anyone have a solution for me?

According to cpap.com, the f30 headgear is a "one size fits all".
I am puzzled--I grew up on the small side, and by necessity, learned to SEW.
Altering headgear is not too challenging.
Put the mask on, and pinch out the excess, using clips to secure.
Once removed, you can use whatever method you like to secure the slack permanently.
