I'm not getting the "rooster tails" at the crown of my head anymore (Yay!) Had I ordered a larger size, the hair in front might also be covered, though. Before, I'd tried several kinds of head covers (scarves, etc.) under my mask straps to stop messing-up my hair, but like this best. The headgear is integrated with the straps on my mask; so that's one less item to wrestle with. The slide-in clip that closes that connects the headgear and the mask, though, is awkward to use (too lightweight, and takes some fumbling to open and close), but is working so far.
This is the most comfortable headgear I've used yet. I use the FlexFit HC452 full face mask. The headgear that came with it is terrible. I have been using the headgear from my old ultra mirage FFM. This Softcap headgear from Philips Respironics tops them all. Very comfortable. The straps are a bit too wide for the connectors on my mask but I make do by just jamming it through them. The staps scrunch up a bit at the connectors but I don't notice.
