We do a lot of early and late season skiing so I decided to make a windscreen to help block the cool air. I searched online for plexiglass and found a local plastic company close to me. I decided to go with a 3/16th thickness tinted piece. They will cut it any size, so I had them cut a 1 1/2 X 3 ft size which cost about $35. I made a template with some cardboard and tape and then traced it onto the plexiglass. I used my circular saw to cut it and a palm sander to smooth everything really good.
