Hello Gustavo! I received my mask a few days ago and it seems that L size is a bit too big (surprisingly, since I was originally aiming for XL) because sometimes it isnt sealed properly (for exemple most of the time when i exhale, air comes out of the side of the mask). So I’ll get a M+ when stocks are back, but I wonder maybe you guys should try to improve that size guide. Maybe adding some width into account? I don’t know. (I have a long face, not wide, maybe that’s why the mask doesn’t fit some part?)
Anyways, other than that, awesome product, it’s super nice on the skin so it’s never itchy or whatever, compared to other masks!
