Lightweight construction and proven impact protection define the Smith Engage Mountain Bike Helmet, built to handle varied trail conditions with confidence. An in-mold shell pairs Zonal KOROYD® with the Mips® Brain Protection System to deliver energy-absorbing, ventilated protection while reducing rotational forces during angled impacts. Extended back coverage enhances overall protection, and 21 fixed vents promote consistent airflow for heat management on climbs and descents. A dial-adjustable fit system provides a secure, customizable feel, while AirEvac™ ventilation integrates with Smith performance eyewear to help keep lenses fog-free. Front eyewear channels allow easy sunglasses storage, and a two-position adjustable visor rotates up for goggle compatibility. Finished with a performance comfort lining and low-bulk webbing, the Engage is tuned for everyday trail riding reliability.
