"Men's Korsa® All Day Crew: The Men's Korsa All Day Crew is a short sleeve running shirt built to move with you from morning workouts to the rest of your day. The semi-fitted cut sits close enough to layer under a jacket but comfortable enough to wear on its own, and the 4-way stretch construction keeps up whether you're logging easy miles, hitting the gym, or just running errands. If you want a technical top that doesn't feel like you're wearing one, this is a solid option.The fabric is 86% polyester and 14% spandex - soft against the skin and moisture-wicking so it pulls sweat away and dries quickly during harder efforts. Flatlock seams run flat against the body to reduce chafing, which matters most on longer runs or when layering. A reflective logo at the back neck adds a low-key visibility detail for early morning or evening runs when light is limited. It's a well-rounded short sleeve tee that handles training without feeling like it's trying too hard.Why Our Fit Experts Love It""I grabbed the All Day Crew for a mid-week run and honestly forgot I was wearing it - no bunching, no irritation, just a clean fit that moved with me the whole time. The fabric stayed dry even when I pushed the pace, and I liked that I could wear it straight to the coffee shop after without looking like I just finished a workout."" - Dave, Road Runner Sports Fit Expert, San Diego, CAWho It's Best ForThe All Day Crew is a great fit for men who want a versatile short sleeve shirt that handles both training and everyday wear without skipping on performance. It works well for runners who prefer a semi-fitted feel over a compression fit, and the moisture-wicking fabric makes it a reliable choice for warm-weather runs, gym sessions, or any activity where you're going to work up a sweat. If you tend to run early or late and want a subtle visibility feature built in, the reflective back-neck logo is a practical bonus.
