Too short
I'm 6'4" tall there seems to be no way to satisfactorily snug this.  I have a 46" chest so it should work, but the back connection for the straps seems too high and, when I tighten the brace to pull my shoulders back it seems to push my neck and head forward, exactly what I'm trying to correct.  It is not awful but, for a big guy, it's really not the right one.
