Perfect head gear for Quattro FX - small!
I have been looking all over for the right size head gear for my Quattro mask. Going through our insurance would have been a huge hassle and would have cost us much more. I found this on here and ordered it right away. It fits fantastically! My mask doesn't leak anymore and I'm sleeping better than I have in about a year. I hope the seller never stops carrying this on Amazon as I will be buying more as soon as I need them.
