Made to Ride. Built to Last.

Designed for long rides no compromises

RiderCore® is built for real riding — not just style. Its ergonomic cut and anti-chafing fabric offer consistent comfort, even after hours in the saddle. Forget the adjustments, focus on the road.

Stay fresh in over 90°F heat

RideFlow™ Mesh keeps airflow constant where it matters most. Moisture is wicked instantly to prevent discomfort or overheating. Even in peak summer, you stay dry and sharp.

✅ 360° airflow zones for full ventilation coverage
✅ Quick-dry bamboo fibers wick away sweat on contact
✅ Breathable pouch design keeps everything cool and supported
✅ Anti-stick inner fabric prevents sweat buildup and skin irritation.

Locked-in fit that never shifts

Whether under leather or reinforced gear, RiderCore® stays exactly where it should. No bunching, rolling, or distractions — just second-skin performance ride after ride.

  • No riding up no sweating

    I tried them under hiking shorts for a 12km trail. They stayed in place and wicked away sweat better than anything else I’ve worn.
