Product OK, but too expensive for what you get
Product works OK, but too expensive. Buy adjustable cap, cut shade off and attach wider Velcro chinstrap bases for much less. Good concept of spreading pressure over entire head, though. Need to tighten cap as it may end up over one's eyes during sleep. Chinstrap location not wide enough to avoid Velcro irritating ears. Chin strap a bit tight, but nature of elastic. I would rate chin strap 4 star itself.<br /><br />My main issue preventing an overall high rating is the cheap nature/quality of the cloth material of the cap/hat (albeit it works) and the excessive lengths of Velcro and cloth bands on the back to attempt to fit any size. It is also a nuisance to sleep on the adjustment ties / lump in the back - why not put on forehead as I doubt users sleep face down with a CPAP mask on ...?<br /><br />For that price the seller should NOT have "reinvented the wheel", but asked an existing cap hat manufacturer to produce a "fit any size" cap for $8-12 without a shade, turned it around so the adjustment would be over the forehead.  Then attached the Velcro base using a width twice the width of the chin strap so - depending one ones head size - one can place the chin strap so the Velcro strap ends don't touch and irritate ears.  Personally I would have preferred the option to have the chin strap be cloth all the way up and not cloth at bottom with elastic higher up so as to minimize the pressure on my chin and cheeks, yet providing a fixed limit as to how much my mouth/jaw could open.
