First Order Mountain Trooper was originally designed for use in Galaxy's Edge parks for guest interaction but sadly never saw the light of day. This helmet should be 501st approvable with proper finishing work and meets all CRL requirements for the hard armor pieces. This listing is just the helmet files.
If you want the whole kit please see my other listing.
