The foam heads will definetley fit your mask
it should do, foam heads are designed to be smaller than a human head! some masks you may strugle with though, strangely, i struggle getting my commander on it but it fits me, lol 
Ok, good, but I hope that my mask isn’t hurt by standing on my shelf in a month without being filled with anything. 
I WOULD FOR RIGHT NOW STUFF IT WITH BAGS TO FILL IT OUT AND STICK IT ON A 2 LITER BOTTLE OF SODA OR A BIG BOTTLE OF VINO THAT WILL WORK JUST FINE, I’VE DONE IT B4
YEA THOSE COMMANDERS ARE TIGHT
lol! the strange thing is though it fits me fine but my head is a little bigger than the foam one 
lol! and yeah, you need to fill it with at least something, go with the soda bottles for now! 
Well…Now I stuffed my mask with four plastic bags but I just can’t get the mask pointing straight. 
Pictures:
just fiddle around with it, it will go straight!
YOU WANNA USE A BIG SODA BOTTLE A TWO LITER, OR 2 WINE BOTTLES TAPED TOGETHER
LIKE THIS:
THERES TWO WINE BOTTLES COVERED IN BLACK CLOTHE UNDER THERE
I heard, on a thread a while back, that foam heads quicken the rotting of your mask. I’ve never put my mask on a foam head before but I know that I never will now
