The Unisex Essentials Compression Calf Tights MX was designed based on specific feedback from sportsmen and women. They are constructed from two fabrics - the main body fabric is a high denier warp knitted fabric, designed to provide a high level of compression and support yet still allowing muscles to function naturally. A lower denier fabric panel at the rear of the tight above the ankle allows for natural extension and contraction of the Achilles tendon, reducing the risk of injury and allowing blood circulation through the feet and back up the legs. Seam placements around the calf muscle provide extra muscle support and lateral stability.
