Flattering design lines with a hidden reflective surface for safety. Carbon helps to lower body temperature, heart rate, and lactic acid concentration in muscles. Lightweight stretch Countermeasure Carbon fabric moves moisture from skin to the outside of the fabric, creating a cooling effect. LogicMesh Lightweight mechanical stretch mesh provides excellent moisture management and temperature regulation. HyperOptic Elastane This state of the art multi layered fabric combines performance stretch elastane with high visibility reflective safety material. The top elastane layer is constructed with a micro eyelet pattern. The reflective material is then bonded below the elastane. In daylight, the dyed elastane colors are visible, while in dusk or night conditions, the micro eyelets allow vehicle lights to reflect off hidden high visibility material, illuminating the fabric. Countermeasure Carbon A high tech blend of polyester, elastane and carbon fibers woven together to create a high perform, lightweight stretch fabric. Carbon fabrics have been scientifically proven to reduce active body temperatures by 3%, lower heart rate by 4BPM and decrease lactic acid concentration in capillary blood by 12% over its polyester jersey counterpart. This means greater muscle productivity during intense exercise and faster recovery time.
