I purchased two of these masks for myself and my son to wear to an upcoming lucha libre event.  My son loves Blue Demon, Jr. and this looked like the best mask option for both of us.  My head is rather large but the mask fit me perfectly.  The lacing in the back of the mask can be adjusted for a comfortable fit, but even on my large melon the seem in the back was completely closed.  The mask fit my son loosely, but he still enjoys wearing it and plans to wear it to the show.

The mask is lightly padded and quite comfortable to wear.  It looks just like Blue Demon, Jr.'s mask, too.  Even though it's a little big for my son, I am still glad that I went with this option instead of the cheaper looking lycra version.
