The BELLAIRO!!!
It's the Frankenstein child of the Pilairo and Bella Loops. I thought this might be helpful for people who find the Pilairo strap too tight, or just not ideal. It can be created without cutting, damaging, or altering any mask parts. Here's a pic (I have Pad-A-Cheek pads on my Bella Loops):

And here's how I made it: gently remove the hook portion of the plastic headgear connectors on the Pilairo. You will be left with a small plastic loop on the pillow part. Take off just the loops from your Bella mask. Line up the loops on the proper side of the pillows, making sure that the outside of the loops (the side with the adjustable tabs) faces the outside of the pillows. Find some soft, non-stretchy material (I used ribbon), and thread through the small plastic loop on the Pilairo, and the Bella Loop. Working one loop at a time, flip the pillow/loop so that the side facing away from your skin is up. Tie in a bow (or something more permanent, if you choose). Voila! The Bellairo!
I slept with this last night, and it was very comfortable. If you have both masks in stock, might be a fun experiment.
