Keep the Gates Away from Your Teeth! The Giro ski helmet chin bar is designed to mount directly onto your Giro Streif, Giro Talon, or the Giro Sestriere ski helmet. All three of these Giro ski racing helmets have pre-drilled holes that accept the screws on the chin bar. The hollow-core Giro chin bar keeps the gates from smacking you in the face, but still allows excellent visibility down the race course. It's super light weight, so you don't have to worry about additional weight.
