Finding the gold visor is no problem at most motorcycle shops, but Im looking for the two toned version like in the nice helmet on the other post. It looks like he used a yellow gold tinted visor and a lighter gold version and stcked them over each other.
Pehaps he/she could post the links to exactly what they used.
You can buy them at motorcycle shops, or you can take a chance and talk to the people at Nucor Yamato Steel, They are a metal making workplace. They use the gold masks for welding. Its the same color orange, onesided view, and extreemly reflective. Check it out!
And if you don't want to talk with them check into welding visors, and yes they are curved, and yes they do cover all of your face, like a big arange bubble mask, but you CAN cut it anyway that you'd like!
