The CALF FLY from UYN(R) supports your high performance. These calf stockings feature targeted compression that increases the oxygen supply to the muscles. CALF FLY is also distinguished by its wearing comfort. Anatomically shaped, it fits perfectly and exerts its functions precisely where athletes need them. Coolvent and Drylight technologies guarantee optimal breathability. First, channels on the inner surface guarantee constant airflow. Second, a special knitting technique permits effective air exchange with simultaneous insulation. Heatmemory also protects against cooling. This means that the material keeps warming you during resting phases. The elastic fabric also ensures an ideal fit - nothing constricts or slips.
