TOP NOTCH!!!
Thanks to the trackside support at Daytona I was able to get measured and get my new undersuit. They were kind enough to let me try different sizes to find the right fit because I recently experienced significant weight loss. The team at Bison has been extremely accommodating during my journey, and with the best gear in the paddock I plan on staying part of the Herd for a long time to come!
