pm on way ..but i should of made this more clear ..its an original JT motor racing strap (circa late 80's I think) so it was designed to go round a helmet aswell as attach to the gogs so if you got a small head (unlike me) it probably wont go small enough.Its more a second strap (agg factor ) due to being a bit of a collectors item ......eh ...if......eh.. your into that sort of thing ...ahemm...yeh I should get out more
