The engineered gradient compression in the SKINS Lady Essentials Calf Tights gets more oxygen to your muscles for enhanced performance when training & competing in any sport. They help reduce the risk of injury by supporting your calf, providing more control over involuntary muscle movement & vibration. The stirrup under the heel keeps the garment perfectly positioned, whilst the anatomic left & right cut ensures a comfortable fit. Fast wicking technology also transports moisture away from the skin & helps regulate your temperature, whilst UPF 50+ provides all round sun protection.
