Hey, I used a welder shield I picked up at Ace Hardware. I did not cut it to fit the shape perfectly, so mine is mounted a bit recessed. However, it was flexible enough to work for the whole shape. It's the Phase II helmet. Let me know if you want a picture. I just used hotglue to hold it in place, I may go back and do a visor cut to shape to get that more flush look. Maybe then I could fit my glasses in the thing!
