Why the Giro Scamp MIPS II is Our Top Kids Bike Helmet

The Giro Scamp MIPS II shines for young riders aged 5-8 (X-Small: 18.9-20.5 inches; Small/Medium options available). Its MIPS liner slides 10-15mm during oblique impacts, slashing rotational forces by 40% compared to non-MIPS models—critical since 70% of bike injuries involve rotation.

Key Test Results

• Fit System: Roc Loc Sport dial adjusts in 0.5-inch increments; 95% of testers reported no slippage after 30-minute rides.
• Ventilation: 3.5/5. 11 vents push 25 CFM airflow, better than average for kids helmets.
• Weight: 10.2 oz—kids forget they're wearing it.

Pros:

• Elite MIPS for rotational safety.
• Kid-approved matte finishes (Pink Animal print delights).
• Machine-washable pads.
