Based on the 400 key points, these SKINS TRI400 Women’s Compression Shorts are cut for swimming, cycling & running comfort. Dynamic gradient compression helps accelerate your blood flow to get more oxygen to your active muscles. Increased circulation also helps reduce lactic acid build-up, so you can push yourself harder to achieve your personal goals. Using Elastic Interface® Technology, the ultra-lightweight TRI400 chamois is designed specifically for triathletes looking for maximum comfort & performance. Flatlock seams ensure reduced drag in the water, optimal compression, fit, muscle wrapping & comfort. Bonded hems on the legs & strategically placed carbon-infused fabric panels between the thighs mean less chafing & a better performance during the final stage of the race. The shorts also feature an internal pocket.
