Body mapping is a technology that is revolutionizing how everything from orthotics and footwear to equestrian saddles and office chairs are made. The technology gives designers the ability to see how pressure and temperature are distributed across an item. The Hincapie Emergence Short Sleeve Jersey uses this new technology to cut panels based on what a rider needs at a specific location. Compression panels are placed to reduce fatigue, ventilation panels are located in high-perspiration areas, and even abrasion-resistant panels are used in high-wear areas. Body mapping gives Hincapie the ability to cut the jersey snug through the torso and waist without restricting movement in the shoulders and arms.The Hincapie Emergence Jersey uses AT1 Dynamic fabric, a lightweight and handkerchief-soft nylon/polyester/elastic blend. The fabric is coated with a hydrophilic finish that speeds wicking and drying to keep you as cool and dry as possible. And while most jerseys require separate panels to offer ultra-breathable perforation, body mapping allows a fabric to be perforated even within a given panel or to have its elasticity altered to give a jersey improved venting on the sides or increased stretch through the shoulders.The outside of the jersey is finished with Schoeller's Coldblack finish. Coldblack helps regulate heat by reflecting environmental heat away from the body and providing a 50+ SPF for significant UVA and UVB protection. Seams are flatlocked for minimal bulk. A full-zip allows you to get maximum ventilation while three rear pockets give you ample room for food and more. A fourth, zippered security pocket is the perfect place for a key or your ID. Reflective accents will keep you visible during dawn and dusk rides.The Hincapie Emergence Short Sleeve Jersey is Coldblack and comes in five sizes from Small through XX-Large.
