ResMed | CPAP Chin Strap Restraint

Resmed chin strap

It works well for me. More comfortable (softer) than some other versions that are similar. Price is high compared to other options. I wear it right under an F30i comfort mask w/o overlapping in order to maintain seal.

Don't work well with a goatee needs more support. it slips and moves around falling off my chin.

Took a couple of days to dial it in. Works very well.
