Lightweight In-Mold Construction: The performance standard for many years, In-Mold construction creates a lightweight helmet with an EPS liner to maximize protection, comfort and value. * Air-Evac 2 Ventilation: The ultimate in goggle-helmet integration, AirEvac 2 connects shell vents and internal EPS channels to increase airflow and evacuate warm, moist air to prevent goggle fogging. Cool, dry air is consistently pulled into the goggle as the warm, moist air is exhausted over the wearer?s head and out the rear of the helmet. * Adjustable Helmet Fit System: Great helmets start with a great fit. Smith?s proven ergonomic head form combined with their Helmet Fit System (HFS) provides exceptional performance and comfort. The soft, flexible plate and liner system contact the back of the head when the HFS is tightened for a proper fit. The self-centering system utilizes an intuitive pinch/pull design with 3 attachment points for easy operation to ensure a correct fit and maximum comfort. * Airflow Climate Control: Airflow ventilation utilizes waterproof vent plugs for easy climate control in all conditions. Removal of vent plugs allows maximum airflow and heat exhaustion in warm temperatures. Installed vent plugs create a warm, dry seal from all Mother Nature can throw at you. * Super soft, Furry Plush Fleeced Tricot Lining: The ultimate luxury in lining technology. A long, brushed and fleeced tricot for additional comfort and warmth.
