Coolshirt Evolution FR Undershirt
Featuring double the tubing of our standard shirt for more cooling, and taking advantage of our race-tested tubing and sewing methods, the new SFI 3.3 Rated Evolution FR shirt is just as rugged and easy to use as the shirts that we started the driver-cooling industry with.
If you have ever wanted more cooling, the Evolution series is perfect for you.
