The Saysky Men's Zig Zag Flow Air Singlet is built for runners looking to perform at their very best. This racerback singlet is made from a high-performance lightweight material to provide a next-to-skin feel that won't get in the way. A ventilated technical design allows for maximum airflow and quick drying times, along with large arm openings to reduce chafing and increase comfort on hard training sessions or on race day.
