Safety The new Cross-Flex Technology is characterized by the lowest residual force values & is therefore one of the safest protectors on the market. The force acting in the fall is transferred to the entire surface of the protector & reduced to a minimum. The back protector meets the standard Level 2. The Cross-Flex protector is unlimited multi-impact & does not lose protection. Breathable Due to the perforated layer structure & the multi-layer construction, the protector is particularly breathable. Additional 3D mesh on the protector provides perfect rear ventilation on the body.
