## Summary description

GIRO Source MIPS is a bicycle/MTB protective helmet in size S (51–55 cm) with a Matte Black finish. It features MIPS technology for rotational impact protection and is designed for everyday and off-road cycling. Adjustable fit and ventilation improve comfort during rides, making it suitable for recreational cyclists and trail riders.

## Long description

The GIRO Source MIPS helmet in Size S (51–55 cm) with a Matte Black finish is a bicycle and mountain-bike protective helmet designed for everyday riding and off-road use. It combines an in-mold shell, targeted ventilation, and MIPS rotational impact protection to reduce rotational forces during certain impacts. The adjustable fit system and padded interior provide a secure, comfortable fit for riders within the specified head circumference range.
Advantages
The helmet integrates MIPS technology to address rotational motion on impact and uses a low-profile, durable shell construction for impact energy management. An adjustable retention system allows quick fit tuning, and internal padding improves comfort and sweat management. Multiple vents and internal channels support airflow to help regulate temperature on longer rides. The matte black finish offers a subdued aesthetic that resists visible scratches and blends with a variety of cycling kits.
Suitable for
Recreational road cycling and commuting
Cross-country and light to moderate trail riding
Daily use where a lightweight, ventilated protective helmet is required
Riders with head circumference of approximately 51–55 cm
When it may not be suitable
This Size S helmet is not suitable for riders with head measurements outside the 51–55 cm range. It is designed for general cycling and trail use; it may not meet specific certification or design requirements for downhill, enduro racing, or motorized two-wheel activities that call for full-face protection or specialized impact standards.
Key specifications
Fit range: approximately 51–55 cm head circumference
Protection system: rotational impact protection layer
Shell: in-mold construction for combined shell and foam integrity
Ventilation: multiple vents with internal airflow channels
Retention: adjustable rear fit system for micro-adjustments
Padding: removable and washable comfort pads
Finish: Matte Black
How to use
Place the helmet level on the head so the front edge sits approximately one to two finger-widths above the eyebrows. Adjust the rear retention system until the helmet feels snug but not overly tight; tighten side straps to form a V-shape under each ear and fasten the chin strap so it allows one or two fingers between strap and chin. Inspect the helmet before every ride for visible damage and replace it after a significant impact or if shell or liner integrity appears compromised. Clean the helmet with mild soap and water and remove pads for periodic washing if applicable.
What to consider before purchase
Measure head circumference to confirm it falls within 51–55 cm
Decide whether MIPS rotational protection aligns with your safety preferences
Consider required use: casual riding and cross-country trails versus downhill or motorized activities
Check compatibility with accessories such as eyewear, lights, or helmet-mounted cameras
Usage recommendations
Use the helmet for daily cycling, commuting, and trail rides where a lightweight, ventilated helmet with rotational impact protection is appropriate. Replace the helmet after any crash that may have caused unseen damage, and follow manufacturer care instructions for straps, pads, and fit adjustments to maintain protection and comfort.
