Engineered to the exact specifications of championship athletes, Nike Pro Combat offers light & tight compression for an ultra-tight & locked-in warm feel. Made from 88% polyester & 12% elastane, the Nike Pro Hyperwarm L/S Compression utilises Nike's innovate Dri-FIT technology. The fabric wicks sweat away from your skin to help keep you cooler, drier & more focused on your performance. Specifically engineered for cold conditions, the thermal insulation has also been created to keep you warm when competing or training in cold conditions. As a compression fit, this garment is designed to enhance your circulation, leading to more oxygenated blood in the muscles. This in turn results in reduced levels of lactic acid meaning a reduction of fatigue & a decreased recovery time between strenuous exercise. A plain black offering, with elasticated waistband & cuffs, is complemented by a flat-seam stitching to help minimise chafing.
