Giro's Register II LED Helmet pairs a rear light with MIPS Evolve Core
Register MIPS II LED helmet runs MIPS Evolve Core underneath a two-piece in-mold shell, pairing a hardshell exterior with a polycarbonate lower wrap fused directly to the liner. Nineteen vents and internal channeling manage airflow, and the Roc Loc Sport dial handles fit adjustment with a single hand.
What Our Gearhead® Experts Are Saying:
"The rear light runs off a coin-cell battery instead of a proprietary rechargeable pack, so replacing it doesn't mean tracking down a specific charger cable. MIPS Evolve Core sits low enough in the shell that swapping helmets doesn't change how the Roc Loc dial sits against my head."
