SKINS Women's Size Chart SKINS DNAmic TRIATHLON Skinsuit with Front Zip is designed to help you cruise through your transitions during training sessions or race day. In the water, strategically placed fabrics minimize drag while you swim; on the bike, an Elastic interface Triathlon Chamois guarantees a comfortable ride; and a wide gripper tape on the thigh minimizes friction while you run. With handy gel pockets in the lower back and a short front zip make it your go-to functional and comfortable trisuit for competitions or training. 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.
