Product Overview

Lightweight, Superior Fit, Comfort, and Cooling

The Seer S2108 is designed specifically for today’s motorcycle police officer. Uni-directional Advanced Composite Carbon Fibers are used to maximize weight reduction. Custom designed fiber angles are used to maximize strength and improve impact performance. A consistent shell thickness is achieved utilizing an all Uni-directional Aerospace Layup technology. The result is a weight reduction of 6 – 10oz.

The S2108 has unique design features which result in superior fit, comfort, and cooling. The shell is designed with a sleek, aerodynamic, low profile outer shell. The composite carbon fiber outer shell is manufactured in 2 unique shell sizes. The inner urethane liner is formed in 4 individual sizes. Cushion pads are included in 3 unique thicknesses which provide a truly custom fit. Large 1/2” air intake holes draw in cool, fresh air. Molded air channels circulate cool air to keep the head cool and comfortable. Each helmet includes your choice of visor and interior.
