Orca Women's RS1 Killa Tri Race Suit Carbon 6  The Carbon 6 Water Repellent coating is applied to fabrics to reduce their drag when swimming. It does this by preventing water from penetrating the yarn. This means that the water glides over the fabric-reducing resistance and therefore increasing speed. Because water is not able to penetrate the yarn the fabric remains dry and so lighter, maintaining the natural buoyancy of the swimmer. FeatherLite  Orca exclusive FeatherLite, is a very light and thin fabric-weight in at just 80gsm  used specifically on the side panels in the body and in the legs throughout the RS1 range. The second-skin feeling it gives is due to its weight, breathability and moisture wicking. Offers excellent UV protection for its lightweight feel. UPF 50+ Protection  UPF 50+ protection means that the fabric is the highest protection a fabric is capable of offering and is rated as Excellent UV Protection. This means that the fabric is reducing your skins UV radiation exposure while youre out there on the course. Meaning you can stay out there for longer without having to worry about sunburn on your skin covered by the garment. HydroSkn  high levels of compression reduce muscle vibration to enhance hydrodynamics. Due to its superior elasticity and recovery the garment will maintain the same level of compression after many races. The super-hydrophobic surface reduces friction between the fabric and the water increasing speed, and minimum water absorption means the garment remains light. Perforated Vapour-Fleece chamois provides breathable comfort on the bike without getting in the way for the run - ideal for short course distances.
