The Quadrant is one serious roost guard. Developed to provide maximum coverage with minimal restriction, the Quadrant features improved chest and back panels that contour the body in the riding position. The ergonomic design incorporates Thor's legendary boxed-rib design that provides both rigidity and natural air channels. This unique approach maximizes airflow without sacrificing strength. Fits most riders 100 - 200 pounds.
