The long-sleeve training shirt Air is a technical layer designed for intense workouts, lightweight as air, and functions like a second skin. With 37.5® technology in high-sweat areas, the long-sleeve training shirt Air offers active temperature regulation that adapts to your pace and environment. Unlike traditional moisture-wicking fabrics, the 37.5® technology uses natural particles that absorb vapor from the skin before it turns into sweat, keeping you dry and comfortable during the toughest training sessions. Combined with lightweight contrasting materials and quick-drying elastane panels, it provides unparalleled airflow and lasting comfort. The flat seams are strategically placed to avoid friction, and reflective details offer added safety during nighttime runs. Lightweight, quick-drying, and naturally odor-resistant, it is a long-sleeve shirt that works with your body – not against it.
