At just 20g in a size S not a gram has been wasted in our pursuit to make this a favourite at speed.

Cut with our trimmest fit to date, it borrows many of the same design cues as found in our proven Race Vest, the bonded neckline and arm holes boost comfort and eliminate chafing. Around the top of the chest and under the bust line, we’ve gone for more streamlined tailoring, making a tighter fit for a racier feel and closing it off with a bonded bottom hem that feels good on the skin.
