Bicycle Safety Vest Where Can Someone Find Bicycle Helmets Made From Recycled Materials?

Where can someone find bicycle helmets made from recycled materials? - bicycle safety vest

I'm not working on a grant for an organization to help create a non-profit rodeo and bike safety to the resources that we need to find the safety equipment from recycled materials (bike helmets, c is considered ie, the cones of safety vests, flags) I have trouble finding manufacturers who will provide these things. The online sites would be great because I can print products and prices. Thank you!
