I had purchased the adult size and they were far too big for my head. I purchased the kids size instead and they for me perfectly. I wore these to PAX Unplugged and they were super cute and comfortable.
Purchased these as soon as they were released and used them all weekend at NYCC. Best fitting mask I've worn, since as a smallish adult it's hard to find face masks that fit well. Very comfortable, well made and my glasses didn't fog up while I wore them! I definitely utilized the filter pocket with so many people around at the con. Thinking about getting a second set to have just in case.
