Based on the 400 key points, the SKINS TRI400 range is cut for swimming, cycling and 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 compete hard from start to finish to smash your previous PB. Using Elastic Interface® Technology, the ultra-lightweight TRI400 chamois is designed specifically for triathletes looking for maximum comfort and performance. Strategically placed carbon-infused fabric panels between the thighs mean less chafing, more comfort and a better performance during the final stage of the race.
