The Pro-Tec Size L helmet is used, but the night vision mount is brand new unused I never used it. This is a very lightweight helmet that is high-quality and it has a Wilcox style night vision mount that is made from aluminum and is also very high-quality for what you're getting. I should also state that the mounting bracket on the Pro-tec helmet is solid metal.

This is a very clean helmet in good condition ready for somebody looking to do night vision and needs the Wilcox style melt. There are two holes on the back of the helmet for a counterweight. I would suggest putting a battery pack there with a couple zip ties or something. Thank you for your interest USA only you get what you see.

Look at the pictures carefully. But this is the highest quality lightest weight helmet.

I could find on the market and it does work good with a counterweight on the back.
