Review (1/5): Not for the big headed or the longhaired
I found this mask dug into my eyes, even if I attached the velcro straps as wide apart as possible. I could literally feel the tug across the mask, over my eyes, inline with the straps. I have a big head, and big fluffy hair, and this mask simply isn't for that set up. I returned them.
The other downside is the velcro straps themselves. Unless you have them completely overlapping (ie as small as possible) or have short hair, your hair will get stuck in the velcro. It sounds awful and it is.
Thankfully I bought two other brands from Amazon when I got these (Dream Essentials and Lewis N. Clark) and they worked much better for me.
