Each sheet of Velostat must be as flush to the top and sides of the helmet as possible Install 8 or more sheets if you can. The minimum number of sheets is 5. Secure each sheet from the back first. Repeat the process over and over until you get 8 sheets into the helmet.
Use enough strips of tape to make the front and back of the Velostat sheets secure to the leather helmet.

Place the remaining sheets of Velostat into the hat using the method just described.


  1. Always start the insertion of the Velostat into the hat using tape on the back of the hat first. This will hold the Velostat secure as you pull it and the had over your head.

  2. Place the strips of tape at the back of the hat at different widths from the center, so the tape does not pile up onto each other.

  3. It is critical to get the Velostat as flush to the inside of the hat as possible, because each layer builds up. Extra space may prevent the insertion of the 8 sheets required for an effective thought screen.

  4. As additional sheets of Velostat are added to the hat, the dimensions of the Velostat become less, so you trim off more of each inserted sheet.

  5. Don't trim the Velostat to the edge the first time, Always try the hat and Velostat over your head at least twice before making the final trim and application of tape.
