Back Inserts are 100% made in Italy back protectors, designed to fit perfectly the special jacket-pockets of the main motorcyclists' technical clothing brands. They are composed by E.V.C. (Evoluted Viscoelastic Cells), innovative waterproof anti-shock material with high performance/weight/thickness rate, perforated to increase perspiration from the contact area to the outside. They are comfortable because they follow and satisfy the natural spinal-column movements and reach Lev.1 performance according to EN1621-2 normative. Their maximum thickness is just 15mm.
