I am curious ... how did you modify the mask cushion?

Oh boy! Anyone who makes these masks would cringe at what I have done to the thing!
Well first let me just mention that my big issue with this mask was that it pinched my nose, making it even harder to breathe! But overall I liked the design, so I set out to tweak it little by little.
First I cut the sturdy inner silicone support on each side of the nose until it no longer pinched my nostrils shut. Then I found that it needed more support around the nose area (go figure ) so I fit a little piece of neoprene into the space between the inner silicone support and the thin silicone skirt that goes on the face. -see photo the neoprene is the blue thing...

This gave the perfect support without any pinching. I used a needle and thread to put a few stiches to hold it in (making sure not to poke any holes in the thin outer skirt, that would really cause air leaks! ) -see photo with mask turned inside out above...

Lastly I cut three tiny little slits in the silicone skirt at the bridge of the nose, this was because it was causing a sore red stripe accross my nose.
So that is it except I also use a little piece of cloth under the mask for comfort and to reduce leaks. The cloth is a sport shirt type material so it has a little stretch and is a tighter weave than tshirt material.
I am crazy perhaps, but it works for me, and it is satisfying to make something that works.
