Expertly designed for MX and off-road performance, the S-M3 Heat Helmet features an advanced thermo-injected shell engineered to provide the optimal balance of impact protection and lightweight agility. This ECE 22.06 certified helmet incorporates a multi-density EPS liner and a patented visor release system to significantly reduce rotational forces during an impact. Optimized ventilation and integrated hydration tube channels ensure superior rider comfort during intense sessions.

Advanced Shell Construction: Features a thermo-injected shell with a specialized polymer blend and varying thicknesses, engineered for an optimal balance of lightweight performance and impact protection (1430g ECE / 1460g DOT).
Maximized Ventilation: Ensures high levels of heat transfer and cooling airflow through 10 strategic intake vents and seven exhaust ports.
Rotational Acceleration Protection: Utilizes a patented low-friction coating on the inner EPS liner that acts as a slip plane to reduce rotational forces during oblique impacts.
Patented Visor Release: Designed to release the visor with a pre-determined force during an impact, effectively reducing stress on the rider's neck.

Engineered inner and outer surfaces designed to minimize the effects of oblique impacts.
Multi-density 5-piece EPS liner system across four densities for optimized impact management and volume control.
Integrated hydration tube channels within the cheek pads for seamless performance and convenience.
Eco-friendly comfort liner constructed from recycled materials to reduce environmental footprint.
Customizable fit via interchangeable crown and cheek pads, available in various thicknesses as genuine spare parts.

Optimized chin area shell thickness and structure designed to exceed standard homologation impact requirements.
Engineered inner and outer surfaces to minimize the effects of oblique impacts.
Emergency Release System with removable 3D contoured foam cheek pads for safe helmet removal.
25mm soft textile chin strap for secure fit and comfort.
Stainless steel D-rings for a reliable and tight closure.
Certified to ECE 22.06 homologation and DOT standards for global use.
