The long-sleeved training shirt Air is a technical layer designed for intense training. It is as light as air but offers the performance of a second skin. With integrated 37.5® technology in high-sweat areas, the long-sleeved training shirt Air provides active thermoregulation that adapts to your pace and environment. Unlike conventional fabrics that wick moisture away, the 37.5® technology uses naturally derived particles that pull vapor away from the skin before it turns into sweat, keeping you dry and comfortable during your most demanding sessions. Combined with lightweight, contrasting materials and quick-drying elastane panels, it offers unparalleled airflow and lasting comfort. The flat seams are strategically placed to avoid irritation, and reflective details provide added safety for night runs. Light, quick-drying, and naturally odor-resistant, it is a long-sleeved shirt that works with your body, not against it.
