Finally, a jersey which doesn't require an undershirt thanks to perforated internal panels strategically located in areas most prone to perspiration. Dryskin AirX is the end result of an R&D project to create a fabric that optimises breathability and comfort. This was achieved using a combination of a highly breathable layer teamed with 3D mesh in strategic areas. The resulting micro air pockets help draw perspiration away from the body and ensure that the waterproof fabric touching the skin dries quickly. CONTROLLED STRETCH: Dryskin has specific elasticity: it stretches to fit the body perfectly, supports muscles just where you need it and never losing elasticity. QUICK DRYING: this fabric has the technological advantage of drying 40% faster than traditional fabrics. WEAR RESISTANT: Dryskin is 80% more wear resistant than traditional fabrics. The DrySkin AirX jersey has evolved and now includes FIR Resistex(R) Bioceramic, a new generation fabric designed to help maintain performance during difficult weather conditions. FIR Resistex(R) Bioceramic is a polyester fabric made from bioceramic material which naturally absorbs damaging ultraviolet UV-A and UV-B rays, as well as reflecting heat by forming a natural barrier against the sun's hot rays. This unique technology keeps the internal layer cool and guarantees freshness and comfort during exercise on hot, sunny days. This ultimately results in noticeably fewer calories, and therefore energy, consumed.
