"Men's On® Performance Long-T: The Men's On® Performance Long-T is a lightweight long sleeve running shirt built for daily training and tempo runs. On®'s DryTec™ fabric pulls sweat away from your skin and dries fast, so you stay comfortable whether you're pushing the pace or logging easy miles. Reflective elements add visibility for early morning or evening runs, and the fit is tailored enough to stay out of your way without feeling restrictive.The construction details on this long sleeve top are what make it work over longer efforts. Smooth bonded hems eliminate the friction of traditional stitched edges, while the seam placement keeps irritation off the table even when the miles add up. Shaped sleeves and a forwarded side seam follow your body's natural movement, reducing bunching and keeping the fit dialed in as you move. A flatlock back seam lies flat against your skin, which matters if you're running with a pack or putting in high-mileage days.Why Our Fit Experts Love It""I took the Performance Long-T out on a tempo run and noticed right away how well the DryTec™ fabric managed sweat - I never felt damp or weighed down.
