Protective children's helmet BELL Sidetrack II MIPS — size Universal 47–54 cm, color Orange Yellow

BELL Sidetrack II MIPS is a children's protective helmet engineered for everyday cycling and recreational use. Designed to fit head circumferences from 47 to 54 cm (Universal size), this helmet integrates MIPS rotational protection to reduce rotational forces in angled impacts. The model features an adjustable retention system and multiple ventilation channels to balance a secure fit with airflow, making it suitable for school rides, scooters, and family outings where both safety and comfort are required.

Advantages

The helmet combines a certified impact-absorbing shell with an integrated MIPS layer to address both linear and rotational energy transfer. An adjustable fit system allows fine-tuning around the head for a stable position during activity, while the ventilation layout promotes air circulation to reduce overheating during active play. Lightweight construction and a user-friendly retention buckle make the helmet practical for frequent use by children.

Ensure the helmet is correctly sized within the 47–54 cm range and routinely check straps, buckles, and the shell for signs of deterioration. Replace the helmet after a significant crash or when fit components no longer provide a secure hold.
