Finally! Science has caught up with your excuses. Introducing the official Slow-B-Gone shirt, inspired by the miracle spray that promises to erase your sluggish lap times one cheek at a time. Engineered using patented RaceChem™ Cotton Blend Technology (also known as “a shirt”), it’s scientifically proven* to make you look 0.2 seconds faster while standing still.

Wear it at the track, in the paddock, or while explaining why you didn't hit a new PB “because of track temps today.” Each shirt proudly tells the world that you take your racing seriously enough to buy this shirt.

Whether you’re shaving seconds or just pretending to, this tee keeps you cool, confident, and questionably aerodynamic.

Spray it. Wear it. Send it.

Because the only thing slower than your lap times is... nope that's it. Your lap times.

Our suppliers provide the measurements. There may be a deviation of up to 2 inches (5 cm) in the product dimensions.

A useful tip! Compare measurements with a product you already own at home by measuring it and matching it to the sizes in this guide.

A Length

Start the tape at the collar's top next to the shirt's highest point on the shoulder. Extend the tape to the shirt's bottom.

B Width

Begin at the seam just under one sleeve and extend the tape across to the seam under the other sleeve.

C Sleeve length

Start measuring from the back center of the collar, follow the top seam of the sleeve to the shoulder, secure the tape at the shoulder, and continue down to the end of the sleeve.
