The LS2 Rapid is the GREATEST VALUE in a full face motorcycle helmet on the market today. The lightweight, aerodynamic shell offers fully adjustable vents, ported through the liner for dynamic flow-through ventilation to keep you cool. We use 2 shells for the smallest, lightest possible helmet in your size. The face shield is scratch and U.V. resistant and can easily be changed without the need for tools. The comfort padding is hypoallergenic and breathable, and uses a neck roll design to seal well and keep wind noise to a minimum. LS2 uses laser cut, 3D foam for the ultimate in comfort and no hot spots. A DOT approved quick release chinstrap provides a secure fit. Certified DOT / ECE. All LS2 visors are built with 3D Optically Correct A Class Polycarbonate, a space-age polymer with high resistance to impact, that avoids distortion and offers maximum clarity. To ensure optimal protection the helmet must fit your head to perfection, special attention should be paid to the shell shape design and materials to minimize the effects of a possible impact. It is key to obtain a perfect fit to your head from outside to inside, as well as the shell, the configuration of the EPS liner, which should match closely the human head shape. All LS2 helmets feature a Dynamic Flow-through Ventilation. Fully adjustable intake ports and vented EPS work with the rear spoiler and exhaust ports to create a constant, light flow of air helping to keep the rider cool and comfortable.
