Bombshell Construction: Bombshell construction uses an injection molded ABS shell to withstand high-impacts and offer unparalleled durability, dent, and ding resistance. If you expect your helmet to be as tough as your truck, Bombshell delivers. * Air-Evac Ventilation: AirEvac uses a system of shell vents to actively pull warm, moist air out of the user?s goggles and exhaust it out of the helmet to prevent fogging * 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. * 14 vents * Convertible Pad Kit included for year-round use. Keeps your head cool in the summer and warm in the winter.
