I bought this for my son's Jason costume. The full costume came with a mask, but it looked cheesy in the pictures, so I purchased this one in addition to it. I'm glad I did! While we were out trick-or-treating I heard a child comment "Look, He has the REAL Jason Mask" to a friend that had another style Jason costume on. It made my 7 year old smile from ear to ear :) It was a little big for him, but was doable. He didn't complain. (He has a pretty large head for a seven year old. I think this is intended for 12-13 years old give or take a few years).
