Children's/Junior Bike Helmet GIRO Register MIPS II — matte motion orange, size Universal 50–57 cm

The GIRO Register MIPS II is a children's and junior bicycle helmet in matte motion orange, designed to fit head circumferences from 50 to 57 cm. It combines in-mold shell construction with MIPS rotational impact protection and an adjustable retention system to deliver balanced protection, comfort and everyday usability for young cyclists. Ventilation channels and a lightweight profile make it suitable for commuting, recreational rides and school cycling.

Advantages

This helmet integrates MIPS technology to reduce rotational forces during certain impacts, together with a durable in-mold construction that bonds the outer shell to the EPS liner for impact energy management. The adjustable retention and sizing system provides a secure fit across the Universal 50–57 cm range, while the matte motion orange finish improves daytime visibility. Built-in ventilation promotes airflow to help manage temperature during active use.

Suitable for

• Children and juniors who need a single helmet to cover growing head sizes (50–57 cm)
• Everyday cycling: commuting to school, short trips and neighborhood rides
• Recreational cycling on paved paths and local bike routes

When it may not be suitable

This helmet is not designed for high-speed downhill mountain biking, BMX competitions, or motorized vehicle use. For adult riders with head circumferences outside the 50–57 cm range, a different size or model is required to ensure proper protection and fit.

Key specifications

• Fit range: Universal 50–57 cm
• Protection system: Rotational impact protection (MIPS)
• Construction: In-mold shell bonded to EPS liner
• Finish: Matte motion orange
• Ventilation: Multiple airflow channels for cooling
• Retention: Adjustable rear fit system and chin straps with buckle
• Weight category: Lightweight design suitable for children and juniors

How to use

Place the helmet on the head so the front edge sits approximately two finger-widths above the eyebrows. Use the adjustable retention system at the rear to achieve a snug, stable fit and tighten the chin strap until it is secure but comfortable: the strap should allow one or two fingers between the strap and the chin. Check that the helmet sits level and does not tilt backward or forward, and verify that ventilation openings are not obstructed. Inspect the helmet before each ride for cracks or damage and replace it after any significant impact.

What to consider before purchase

• Measure head circumference to confirm it falls within 50–57 cm
• Decide if MIPS rotational protection is a required feature for your use
• Consider visibility and color preference—matte motion orange enhances daytime visibility
• Check compatibility with accessories such as hats, eyewear or helmet-mounted lights

Usage recommendations

For effective protection, ensure the helmet is worn correctly on every ride, replace it after any crash, and keep straps and retention mechanisms clean and functional. Use the adjustable fit to accommodate growth within the 50–57 cm range and pair the helmet with age-appropriate safety habits like reflective clothing and safe riding routes.
