Designed to provide maximum aerodynamic efficiency and optimal performance, the Louis Garneau Course M-2 Triathlon Skin Suit is all about speed, from start to finish. CB SpeedTech fabric has a dimpled mesh construction that improves aerodynamics for speeds from 15 to 45mph/h. Ultra-texturized coldblack M-2 sleeves allow better laminar airflow to reduce the rider's drag factor. coldback Gladiator and Lazer Rev fabrics offer powerful muscle compression, moisture management and heat regulation. The skin suit's full zip can be completely opened for maximum ventilation without flapping. Pre-shaped shoulders and comfort-designed neck accommodate a full range of motion, seamless inner leg reduces bulk and excess material that causes saddle bunching, and lazer-finished thigh and sleeve hems provide a smooth, sleek fit. Quick-drying Tri Elite chamois with antibacterial top layer gives great support during the bike phase and maintains comfort during the run and swim phases. Two inner pockets are designed close to the body, so gels and bars can be easily accessed without affecting aerodynamics on the bike or comfort while running.
