Trail-ready protection meets airy comfort in the Source MIPS Helmet for long, hard rides
What Our Gearhead® Experts Are Saying:
"I’ve been riding in this helmet for everything from after-work trail laps to long weekend grinds, and it just disappears once I’m rolling. The MIPS liner adds peace of mind, the Roc Loc 5 dial lets me fine-tune the fit mid-ride, and the ventilation actually keeps air moving on hot climbs."
When we’re dropping into familiar singletrack or pushing into new trail systems, the Source MIPS Helmet keeps us focused on the ride instead of what could go wrong. Giro built this helmet for riders who want dependable protection without a bulky feel, so we can stay loose and confident whether we’re climbing for miles or picking our way through technical descents.
The integrated MIPS liner helps manage rotational impacts, while 17 well-placed vents channel airflow to keep heat from building up on sustained efforts. An adjustable visor dials in sun protection for changing light, and Giro’s Roc Loc 5 system makes it easy to lock in a secure, comfortable fit before we roll out or mid-ride.
