ORCA Women's RS1 Killa Tri Race Suit LIGHTWEIGHT BREATHABILITY - FeatherLite fabric on the lower body combined with HydroSkn on the upper body gives you the ultimate mix of hydrodynamics and breathability with the lightest weight possible. COMFORT - Perforated Light Brush chamois provides breathable comfort on the bike without getting in the way for the run - ideal for short course distances. DRAG REDUCTION - A combination of the more advanced HydroSkn Dry water repellent coating and the Carbon6 water repellent coating reduces drag in the water and so increases swim speed and retains natural buoyancy due to the prevention of water entering the fabric. ULTIMATE STRETCH - Fully bonded seams make the silhouette of this suit smoother, making it glide faster through the water and more aerodynamic on the bike. This stitchless construction also promotes greater stretch for increased comfort.
