HELP - Disguise Master Chief Helmet Sizing

[Yuraichu]

Hey I am in need of some guidance for those who have bought either the child or adult sized Halo 4/5 Master Chief Helmet from Disguise. I've been scouring the internet for the internal measurements for the helmet before I purchase it but could not find any. Does anyone own one of the those helmets? I feel it would be better if I came to ya'll directly for a more accurate information.

I have one of them, will respond when home from work. Overall it’s pretty big in diameter but short vertically, my chin pops out when talking

I won't lie but I'm not even sure if the helmet is from Disguise (pic), I saw that very notable red line/seam on the skirts of the visor and I could not see that in many of the Disguise helmets that I could find
