The Skins A200 range is the evolution of the pioneering Original collection. Built on SKINS' scientifically proven engineered gradient compression, the SKINS A200 Thermal Long Sleeve Top with Zipper features muscle wrapping support for stronger support that provides heightened performance. This garment is designed for those that are passionate about being active whether it running, playing team sports or hitting the gym. This top features a mock neck for added coverage in cold. GRADIENT COMPRESSION: SKINS gradient compression has been engineered to provide the correct level of surface pressure to specific body parts, enhancing circulation and delivering more oxygen to active muscles. Increased circulation also helps eliminate lactic acid build up and other metabolic wastes so you can go harder for longer and recover faster. FOCUS: SKINS wrap and support key muscle groups which reduces vibration and helps maintain muscle alignment. The seams on SKINS are strategically placed to act as 'anchor points' offering focused support and stability. The fabric in skins is warp knitted using multiple fine quality yarns to giver superior performance. Warp knit fabrics have no natural stretch - instead, the spandex mix ensures specific levels of elasticity and perfectly controlled compression. Some other compression brand use circular kit which has a natural stretch, making it hard to maintain the correct level of compression. Circular knit fabrics are also less durable and likely to run if snagged. Warp knit construction has a 'float line' between loops to aid moisture management. Multiple yarns are used for added strength and to eliminate running if the fabric is torn. The SKINS logo features more prominently along with a higher density signature SKINS contrast stitching. In addition features moisture wicking, temperature management and 50+ UV protection.
