SCOTT TruView lenses are lightweight and block 100% of harmful UV rays. TruView lenses pass SCOTT’s strict testing procedures delivering high quality, performance lenses. Different to traditional SCOTT MX lenses, this Prospect Works lens comes with 4 works pins instead of 2. The 4 pins provide more stability for the tear offs. With this system the tear offs will always remain tight to the lens and provide the rider a better vision.
