"Men's Korsa® Fly Short Sleeve: The Korsa Fly Short Sleeve is a men's short sleeve running shirt built for warm-weather training and active commutes. Mesh construction and moisture-wicking fabric keep airflow moving as your effort climbs, so you stay comfortable whether you're logging morning miles or heading into the office after a ride. The slightly longer back hem gives you coverage and freedom of movement without getting in the way, and flatlock seams run smooth against the skin to reduce friction over longer efforts.Reflective branding on the front and back body adds visibility in low-light conditions - a practical detail for early morning or evening workouts. The fabric blend of 88% recycled polyester, 3% polyester, and 9% spandex moves with you and dries quickly, making it a reliable option for high-output sessions when you need a technical top that keeps up. It's a well-considered short sleeve shirt that handles the demands of training without sacrificing a clean, put-together look.Why Our Fit Experts Love It""I wore the Fly Short Sleeve on a warm morning run and noticed right away how well the mesh breathes when you start pushing the pace. The flatlock seams are genuinely smooth - no irritation even after a longer effort. The reflective branding is subtle but actually useful when you're out before sunrise."" - Sean, Road Runner Sports Fit Expert, Chula Vista, CAWho It's Best ForThe Fly Short Sleeve is a strong pick for men who want a breathable, moisture-wicking running shirt that works just as well for a morning run as it does for an active commute or cross-training session.
