This Pro-Tec Ace SXP Chris Doyle Helmet comes in Metallic Blue with a Mustard Yellow Chin Strap. This is the Helmet you will see the Top Pro Riders wearing, featuring Pro-Tec's Multi-Impact SXP Technology for Maximum Protection and Longer Lifetime. Regular EPS Foam Liners crush and stay crushed when it takes a hard hit, so it's protection is reduced. The SXP Liner expands after compression, returning to it's original shape to give Maximum Protection time-after-time.
