This is a Necksgen neck safety, restraint system. Safety, critical, especially neck protection in any kind of motorsport racing application. Let me show you how this works. You simply put an arm around your neck. As you can see these tethers here Connect actually to the helmet themselves. And then the safety belts come across here. When you snug everything down, it keeps your neck from going forward, or obviously backwards if there is a situation of a collision or anything. 

Necksgen offers high quality racing head and neck restraint systems (HNR). They produce some of the highest quality, lightest devices available today.

So that’s it. I just wanted to show everybody the application. You can find this as well as a number of other brands that sell the same neck and safety restraints at https://uzbasicmotorsports.com/necksgen/.
