Crafted directly from Alpinestars' MotoGP racing department, this back protector delivers the highest levels of performance required for back protection thanks to its innovative mesh structure.

The next-generation structure, made from a perforated viscoelastic PU compound, along with the additional central reinforcement plate, significantly increases spinal protection and comfort, making this back protector flexible and ergonomic to adapt to any body shape during use. The KR-3 features two additional polymer inserts in the rib area, further increasing the level of protection. The central shell also extends to the shoulder blade area, protecting the acromion, a small shoulder bone often prone to injury. The lower part can be extended using the KR-TB coccyx protector (not included).

The height-adjustable lumbar strap with Velcro allows for a precise and ergonomic fit. The braces are removable for use under a racing suit or to equip it with the KR-Ci chest protector (not included).
