Hans is a brand name. Alot of people miss use the name calling any neck restraint a hans. Mine is a necksgen. I prefer this one for several reasons. Its very comfortable and easy to get on and off. Its more comfortable in the high back seat.The reality is this Racing with a helmet on can be more dangerous if you were to crash and not hit your head. The extra mass from the helmet contributes to the neck over extending upon impact. The body is held in place with a restraint system. The head has nothing. Your neck becomes a slinky. Thats were the danger is. Thats what causes neck injuries. Thats what killed ernhardt. The restraint connects to the helmet keeping the spine intact. The cheaper the helmet the heavier it is also contributing to neck injuries. They dont make carbon fiber helmets to just look cool.
