Up for sale is a carbon fiber rib vest specifically made for protecting the kart racer from the mechanical stresses imposed on the rib cage.  This is made by K1 Racing Gear and is a Size M (medium).

The following information is taken from the website of K1 Racing Gear and describes the benefits of the vest:
"A rib vest helps absorb and evenly distribute impacts and vibration directed through the chassis into your body, helping reduce the chance of injury and allowing you to focus on the task of driving, rather than discomfort or exhaustion. The constant vibration of an endurance event can slowly wear down your body, but a rib vest can help fight off this process and give you the strength you need to stay competitive."

According to the website's sizing chart, size M (medium) is designed for a person with a chest measurement of 38 to 40 inches.  There is some degree of adjustability in this vest, in the form of four buckles, two that join the two carbon fiber plates across the front of the chest and two that join the shoulder straps to the top margin of the vest.

The tag on the inside back top of the vest reads:
"Made of carbon fiber
inside cover with
Jean fabric 65/35
Outside cover with
100% polyester fabric.
DESIGNED IN THE USA
MADE IN PAKISTAN"
