Kawasaki Teryx Window Net from ShockPros Motorsports. Doors are not just for the winter!! Our optional upper door net system works with your existing doors for the warm ridin months. Swap out your upper soft window section for the NETS in the summer. Keeps branches and debris from cab area. OH ya makes your machine look kinda like a Baja 1000 racing truck too!!! Very very cool (no pun intended) color choices to match your existing doors too (black,green,camo).
