Brand: Simpson Performance Products
This helmet support collar from Simpson fits around the driver's neck to take the weight of the helmet off the neck muscles, reducing fatigue during a race. A hook-and-loop flap allows a wide range of adjustability, and the woven Nomex® cover can be removed for cleaning. The resilient foam core can be shaved down to customize the fit if necessary. The 360 degree round style goes all the way around your neck and is approximately the same height all the way around. Sold individually.
