The extremely lightweight, CE-certified KR-CELLi Protector insert features an articulated back shell plate for flexibility and riding fit, plus an advanced micro-structure cell design for efficient impact energy absorption and high airflow levels. The horizontal flexion grooves give an adaptive fit in different riding positions. Soft, comfortable air mesh on the body side of the protector offers maximum breathability and rider comfort. The triple-segmented back shell plate is constructed from a high-performance polymeric material blend for optimised flexibility and excellent weight-saving properties. It is CE certified to EN 1621-2:2014 Level 1 and is developed in three waist-to-shoulder dimensions to cover all body sizes. The back protector's structure design and structural change from the centre towards the outside provide the perfect balance between force dispersion and energy absorption.
