Featuring deep coverage with aggressive ventilation from 17 vents coupled with deep internal channeling, it helps keep things cool even when the riding gets rowdy. With the comfort and secure feel of the Roc Loc™ 5 Mips fit system with Integrated Mips brain protection, plus a moto-style adjustable screw-in visor and full lower Hardbody durability, you get a helmet that's capably equipped for fun and adventure.
INTEGRATED MIPS® BRAIN PROTECTION SYSTEM: All Giro helmets are designed to reduce as much energy as possible while meeting and exceeding stringent safety standards. The goal of Giro's Integrated Mips®-equipped helmets is to reduce rotational forces while enhancing fit and comfort by combining the Mips slip plane with the helmet's adjustable fit system. Giro believes that helmets equipped with this technology can reduce the amount of rotational force that may be transferred to a rider's brain in certain impacts.
WIND TUNNEL INTERNAL CHANNELING: Giro helmets are developed utilizing our proprietary Wind Tunnel ventilation system. This elaborate design combines active vents in the helmet's shell with exhaust channels inside the helmet that thrust fresh, cool air over and around the rider's head while forcing heat and stale air out. It's the most effective cooling system available, and a difference you can feel every time you ride.
ROC LOC® 5 FIT SYSTEM: The industry benchmark in comfort, stability, adjustability, and weight savings. In addition to enhancing the comfort and stability of helmets, Roc Loc® 5 allows you to easily custom-tune the fit tension and fore-aft tilt of a helmet in seconds, using a single hand. It's also lighter than comparable systems, making it the ultimate in skull-hugging luxury.
TOOL-FREE BOLT-ON VISOR: Easily adjustable without the need for tools or extra fiddling, and offers plenty of vertical adjustment to stage goggles when you're not wearing them.
IN-MOLD LOWER HARDBODY™ WRAP: The In-Mold process permanently fuses a light-yet-tough polycarbonate shell to the foam liner, eliminating adhesives and excess weight. Our Hardbody design extends that coverage to the inside of the helmet to enhance durability.
ADJUSTABLE MOTO-STYLE SCREW-IN VISOR: This visor features an adjustment mechanism that lets you move the visor up and down in indexed steps. These steps include three riding positions plus a high position for goggle storage above your brow. The design allows you to easily adjust your visor with one hand while riding.
Complies with the US CPSC Safety Standard for Bicycle Helmets for Persons Age 5 and Older. CE EN 1078.
The Giro Source Mips helmet is designed for adult mountain bikers seeking robust protection and advanced comfort on rugged trails. Its key benefit lies in the integrated Mips® system for enhanced safety and aggressive ventilation to keep riders cool during intense activity. A potential caveat is the full-face design, which may offer less ventilation than open-face helmets. This helmet features deep coverage, 16 vents with internal channeling, the Roc Loc 5 Mips fit system, an adjustable moto-style visor, and In-Mold Lower Hardbody™ durability.

FAQs
What is the Integrated Mips® Brain Protection System?
Integrated Mips® is a low-friction layer built into the helmet's fit system. It is designed to reduce rotational forces transferred to the brain during certain angled impacts, enhancing the helmet's safety.
How do I adjust the Roc Loc 5 fit system?
The Roc Loc 5 system is adjusted using a dial located at the rear of the helmet. Turn the dial clockwise to tighten and counter-clockwise to loosen the fit for a secure and comfortable experience.
Can I store my goggles on the visor?
Yes, the moto-style adjustable visor features a high position specifically designed for conveniently storing your goggles when you're not wearing them.
What is the In-Mold construction?
In-Mold construction permanently fuses a tough polycarbonate outer shell to the helmet's impact-absorbing foam liner. This process eliminates gaps and adhesives, creating a stronger, lighter helmet with enhanced durability.
Does this helmet comply with safety standards?
Yes, the Giro Source Mips helmet complies with the US CPSC Safety Standard for Bicycle Helmets for Persons Age 5 and Older, as well as CE EN 1078 standards.
How many vents does the helmet have?
The Giro Source Mips helmet features 16 vents with deep internal channeling designed to provide aggressive ventilation and airflow.
Troubleshooting
Helmet feels too loose or wobbly.
Adjust the Roc Loc 5 fit system using the rear dial. Ensure the cradle is positioned correctly on the back of your head. Check that the straps are adjusted properly.
Visor adjustment screws are difficult to turn.
Ensure the screws are clean and free of debris. If they are stiff, you can apply a small amount of lubricant (e.g., silicone spray) sparingly to the screw threads, but avoid contact with the helmet shell.
Padding feels uncomfortable or is causing irritation.
Remove and hand-wash the internal padding. Ensure it is fully dry before reinserting. If irritation persists, check for any rough seams or contact points and consider replacing the padding if worn out.
Ventilation seems insufficient on very hot days.
While designed for airflow, extreme heat may still lead to rider warmth. Ensure the helmet is properly positioned on your head for optimal airflow. Consider taking short breaks in shaded areas.
