All it needs is DOT approval : )

      The invisible "bike" helmet.   

Hövding krocktest

[Oss]

how do they do that
sort of the same theory behind my  hit-air jacket?

They make the hit-air as a vest and a jacket   Mine is 6 yrs old now

bought it off the bike bone site, never had it go off, even when I forget to unhook getting off the bike

hope I never do need it but in 1/4 second  it fully protects better than any leather can

I will be wearing it down to friendswood in april if anyone wants to try it on
