Predator Bio Mask

I had this one in the pipe line to do properly for a couple of years and I guess with the release of the new Predator 4 movie, then nows the right time to release it : )
P.S. Check out ReefDudes awesome build for some extra ideas.

And as always, check the sizing is going to suit your needs Cheers Jace
