Smith Sidekick Jr. MIPS Helmet Matte Forest

Lightweight in-mold construction and kid-specific protection define the Smith Sidekick Jr. Mountain Bike Helmet, delivering real trail-ready safety in a youth-focused design. The integrated Mips® Safety System helps reduce rotational forces during angled impacts, while extended back coverage mirrors the protection found in adult MTB helmets. Twelve fixed vents provide consistent airflow to keep young riders comfortable across sidewalks, pump tracks, and trails.

Designed to dial in a secure fit, the Sidekick Jr. features an adjustable dial fit system and is offered in two youth sizes for accurate sizing as kids grow. AirEvac™ ventilation integrates with Smith eyewear to help reduce lens fogging, while an integrated visor, performance comfort liner, and low-bulk webbing round out a helmet that blends comfort, safety, and big-kid mountain style.
