Alpinestars Nucleon KR-3 Back Protector

Upgrade your riding safety with the ultimate spine defense. The Alpinestars Nucleon KR-3 Back Protector is a premium, CE Level 2 certified motorcycle back protector engineered to offer superior impact protection, outstanding ventilation, and a custom anatomical fit. It features an innovative hybrid construction combining a single-injected lattice structure shell made from a high-performance polymeric blend with a soft viscoelastic PU foam compound on the central spine area. This ensures excellent weight-saving properties, optimized flexibility, and maximum breathability while effectively absorbing severe impacts. A specialized convex design on the central hard shell delivers the highest level of coverage for the spinal area, complemented by adjustable rib protectors and shoulder blade padding extensions to safeguard vulnerable zones.

Designed for an adaptive fit in all riding positions, this protector incorporates horizontal flex grooves, a waist adjustment system, and a slim, vented kidney belt for enhanced position stability. The adjustable, detachable elastic shoulder straps utilize a convenient snap-fit system to maintain a comfortable feel under your outer garment. Fully compatible with Nucleon KR-C and Nucleon KR-TB protectors and developed in three waist-to-shoulder dimensions to cover all body types, it lets you hit the road with complete confidence. Take your next motorcycle journey to the next level by gearing up with this elite safety equipment from RIDE Adventures.
