What Our Gearhead(R) Experts Are Saying:"I've raced in the Elite Swim Skin and it's seriously impressive. The bonded seams and stretch-woven fabric make it feel like a second skin, cutting through the water without restriction. It's fast, comfortable, and stays put the entire swim-exactly what I need for non-wetsuit races where every second counts."We trust the Elite Swim Skin from Castelli when performance and precision matter most. Designed for non-wetsuit triathlon swims, this sleek, hydrodynamic layer is built to help us move through the water with unmatched speed and comfort. Engineered from a high-stretch woven fabric with water-repellent finish, it provides a compressive, second-skin fit that reduces drag and enhances glide. Castelli's nearly seamless construction, with bonded rather than stitched seams, minimizes irritation and improves hydrodynamics. A long YKK(R) rear zipper with an elastic closure prevents accidental opening mid-race, while woven-in leg grippers keep the suit securely in place during powerful kicks. Developed from Castelli's work with elite triathletes, the Elite Swim Skin brings professional-level performance to any non-wetsuit race day.
