Ideal for open water swimming or triathlons. Used less than five times and in excellent condition. The bright pink back will help you stand out in the water too! From the website: The Viper Pro is the tip of the sword in the triathlon swimskin (aka "speed suit") market. In designing the Viper Pro, we relished the challenge of creating a swimskin that lives up to the ROKA standard set by the Maverick Pro wetsuit. We took the same uncompromising, ground-up design approach based on years of competitive swimming and triathlon experience, and we strategically incorporated all the latest advances in performance swimwear materials and construction. The Viper Pro swimskin is USAT and WTC legal and uses two varieties of the same premium stretch-woven textile from Italy, a hydrophobic Teflon® coating, high-tech bonded seam construction with novel hidden stitch reinforcement, a low profile autolocking YKK zipper and a pattern orientation and layout strategically designed to liberate your arms while providing support where you need it. We use flat seams at the leg opening to avoid "sausage legs" created by elastic bands with silicone grippers. All of these little details add up to free speed on race day. The Viper Pro comes with atomic yellow graphics for men and magenta graphics for women. If you have a non-wetsuit race on your calendar, the ROKA Viper Pro offers the ultimate in swimskin performance.
