Troy Lee Designs A2 MIPS Bike Helmet

When the trail gets technical, your helmet needs to keep up. The Troy Lee Designs A2 MIPS is built for riders who demand full-spectrum protection without sacrificing airflow or style. Whether you're threading singletrack or pushing your limits on the descent, the A2 has you covered from every angle — literally.

Multi-Layer Impact Protection

The A2 combines dual-density EPP and EPS foam in a co-molded construction that manages energy across both low-speed and high-speed impacts. The integrated MIPS slip-plane liner moves 10–15mm in all directions to redirect rotational forces away from your brain — the kind of protection that matters most in real-world crashes.

All-Day Comfort on the Trail

• X-STATIC® pure silver comfort liner — wicks moisture and naturally resists odor, ride after ride
• Multipurpose cam-lock adjustable stabilizer — dial in your fit without stopping
• Full-spectrum adjustable visor — adapt to changing light conditions on the fly
• Anodized aluminum hardware — built to last through seasons of hard use
• Huge air intakes — keep airflow moving so you stay cool on the climb
