I don't understand why you have a small/wide mask. The medium is smaller according to the sizing sheet. I use a small in other styles and the small/wide is too wide! And a regular frame only at first rather than being able to pick small, medium, or large. Since I was one of the first in my area in the US to request the F40 on recommendations from Australia, I didn't have a choice or a sizing sheet. But I do like the mask, I just have to get it centered often. I am exchanging a small/wide for a medium so I hope that fixes the leak problem.
