Source Mips Helmet

What Our Gearhead® Experts Are Saying:

"I reach for this helmet when I want modern safety features without extra weight. The MIPS system and solid coverage inspire confidence, while the venting and fit adjustment make it comfortable for all-day trail rides."

The Source MIPS Helmet is designed for riders who want modern impact protection paired with all-day comfort on the trail. Giro integrates a low-profile MIPS liner into a lightweight polycarbonate shell to help manage rotational forces during certain impacts, adding an extra layer of security without compromising fit or ventilation. The result is a helmet that feels streamlined and confidence-inspiring from the first pedal stroke.

Ventilation is handled by 17 strategically placed vents that promote continuous airflow, helping regulate temperature on slow, technical climbs and fast, exposed traverses. Giro’s Roc Loc 5 fit system allows for precise micro-adjustments, ensuring the helmet stays secure over rough terrain while remaining comfortable on longer rides. An adjustable, screw-in visor adds practical protection from sun and trail glare without rattling or shifting.

Whether we’re logging weekday trail miles or heading out for longer weekend rides, the Source MIPS Helmet hits the sweet spot between protection, airflow, and fit. It’s a reliable choice for trail riders who want proven safety technology and a comfortable, dialed-in feel for consistent performance on varied terrain.
