The trail beckons with the all-new Youth A1 helmet from Troy Lee Designs. Ready to conquer any ride, the A1 leads the way with 16 large air vents and the innovative MIPS® system to go along with its EPS liner for outstanding impact protection. With all-mountain performance and safety in youth-specific shell size, the A1 goes where no youth mountain bike helmet has gone before.
MIPS stands for Multi-directional Impact Protection System, it is a revolutionary technology that lets the helmet slide relative to the head, adding more protection against rotational violence to the brain caused by angled impacts.
