Race ready, with great features for the extreme dirt rider. HJC uses an advanced fiberglass composite shell for weight reduction in the AC X3. Different from the X5, the X3 has an integrated chin vent that reduces dirt clogging. Packed with features, I-beam chin construction for the best protection and anti slip goggle strap holders, safety and performance dominate. Designed exactly like the carbon version, but a little more wallet friendly.
