Basically the strap keeps getting longer. My solution has been to shorten the strap by putting a few stitches in the strap on each side of the split to take about an inch out of the length each time.
My problem is that this strap is supposed to last a year. I can't even make it 3 months without it getting so lose that it falls off of my face within an hour or so. I just made adjustments to the sides again and I think I might have made it too tight this time because now I am waking up around 5am or earlier with a sore nose right between the nostrils.
So my 6 months on this mask ends Oct 8.
I would like to find a different mask that is similar to the Airfit P10.
I really like how the P10 doesn't feel like you are strapped in. But I don't think it is doing me much good if I can't keep it in place. Basically a P10 with adjustable straps would be awesome...
