Never really liked Save Phace masks. But that first one gets me. Pull the top visor thingy off (like in pic), and I would use it. Coverage isn't great.. But then again, I wear E-Vents... They actually give me some good coverage though.
I got mine in the Scar Phace paintjob. Very scary and Ive scored some kills from guys reluctantant to drop the hammer on me. it doesnt really cover the jaw line per se, but i wear a neck protector, and ive never gotten hit in the jaw. it would suck though.
