Just how big is this mask? Thanks guys 
Not as big as a TOTS H1.
I think it’s about 24"- 24.5."
The boogeyman mask is larger than the H40,
and smaller than the H1 or H2.
H40 is approximately 23.7" and H1, H2 is 25".
Hope this helps 
Would fit my noggin a bit loose, but with how my 78 looks with a beanie and velcro, it’ll probably be fine.
That’s great news!
Hopefully mine will be at the 24 mark.
Might have to use Velcro! Idk about wearing a beanie that would be uncomfortable for me haha.
I don’t have the Shape anymore to compare it to but here it is next to my H40. It’s a pretty good sized mask but not gigantic.
So maybe just a tad bit bigger than the H4 is what I’m guessing. The size in the pic looks similar to when I put my H4 and H40 side by side.
