At PROTOform, aerodynamics influence every detail put into every race body. In fact, the 20 IFMAR World Championships won by PROTOform racers are the best evidence that aerodynamics play a huge role in the performance of R/C cars . We take aero seriously, and now you can show that you do too with the PROTOform Aero Matters T-shirt. Large, bright letters and our PF Crest on the front will make a big statement around the pits, complemented by the PROTOform logo on the back. This black shirt has a classic fit made from 100% preshrunk, 6.0oz ringspun cotton.
