The SEESOFT/SEESOFT AIR multi-layer back protector delivers adaptive impact absorption that doesn’t compromise comfort, ventilation or flexibility. The highly impact-resistant blend of Nitrile and Polynorbornene rubber results in a memory foam that is multi-impact rated and CE certified to the highest level ( EN 1621-2:2014 - level 2). Through the application of multiple-layer technology, REV’IT! has developed a back protector insert that remains flexible. The individual layers themselves have been carefully designed to meet motorcyclists’ very specific impact-absorption needs. Additionally, the shifting layer concept provides extra protection in the event of a crash. When a rider encounters an impact the individual memory foam layers shift relative to each other, which disperses the force of the crash over a larger surface area and effectively minimizes the force that is transmitted to the spine and back.
