SMK's Stellar helmet is an aggressively styled helmet designed for the fashion-conscious motorcycle rider. Two shell sizes (XS-M and L-2XL) allow for a precise fit no matter your head size. A multi-density EPS liner and EIRT (Energy Impact- Resistant Thermoplastic) shell provides great protection when required. The aerodynamic shape of the helmet reduces stress on your neck, allowing for a more comfortable ride. The Stellar includes a breathable hypoallergenic liner that is fully removable and washable. Air intake vents provide constant cooling while channelled exhausts allow hot air to escape for excellent, flow-through ventilation. Shell and EPS Construction: Two sizes (XS-M and L-2XL).
