Brevida Headgear issues

The headgear that comes with Brevida is too large for me. I read the posts about headgear that is too large; I don't think sewing would work well in this case, and there is no back section to pad. I am using the 20cm wide, fully adjustable Q CE 0123 headgear from the Pilairo, which fits, but I have to put adhesive tape on the clips to keep them attached to the frame. Fisher & Paykel needs to make a similar 20 cm, fully adjustable headgear as an option for Brevida. Other than that, the Brevida is better than Pilairo: It is quieter, fits well, and my face is not wet in the morning from the humidifier.
