The Nucleon KR-3 back protector has been developed in three sizes from the waist to the shoulder to accommodate all body types. The mesh back shell is made from a high-performance polymer blend that optimizes flexibility and weight, combined with a soft viscoelastic PU (polyurethane) foam construction. It features a unique injected mesh shell with an ergonomic design that absorbs impacts while allowing for maximum breathability and air circulation. The Nucleon PU foam in the central spine area provides additional shock absorption performance. The added convex design of the central hard shell offers the highest protection for the spinal area. Horizontal flex grooves allow for adjustments in all riding positions.

The adjustable rib protector is made from a blend of high-performance polymer materials for additional lateral protection. The larger shoulder padding is designed to protect the shoulder blade. The adjustable waist belt ensures a personalized fit, while the slim, ventilated back strap enhances positional stability. It also includes adjustable, removable elastic straps with a clip system for added comfort. This product is compatible with Nucleon KR-C and Nucleon KR-TB.
