SKINS Women's Size Chart Cruise from the swim to bike to run with ease in SKINS DNAmic TRIATHLON Half Tights for women. SKINS has combined their best compression tech to boost oxygen supply to your leg muscles with comfortable features like an Elastic Interface Triathlon Chamois and friction-reducing wide gripper tape on the thigh for hassle-free transitions between stages on race day. Features: - Dynamic Gradient Compression: SKINS most advanced compression technology increases muscle oxygenation, stabilizes active muscles and reduces blood lactate build up, to enhance performance and speed up recovery time. - SKIN fit: SKINS unique sizing system is based on the SKINS unique Body Mass Index (BMI)/anthropometrical algorithm, because you only get the full benefits of gradient compression if your SKINS fits you properly - Muscle Focus: Biomechanically positioned panels and seams support and stabilize the muscles to reduce fatigue and risk of injury. - Memory MX: Memory MX Fabric has a superior high-stretch yarn that doesn't change shape or sag, so you maintain consistent compression, session after session. A400 Long Tights have 70D Memory MX over the knee and Achilles tendon for unrestricted natural movement, and 210D Memory MX over the ITB and TFL muscle groups to help reduce the risk of injury.
