Long Sleeve Air men's

The Long Sleeve Air is a technical layer built for high-output training engineered to feel light as air but perform like a second skin. With 37.5® Technology integrated in high-sweat zones, the Long Sleeve Air offer active thermoregulation that adapts to your pace and environment. Unlike traditional moisture-wicking fabrics, 37.5® uses naturally derived particles that pull vapor from the skin before it becomes sweat – keeping you dry and comfortable through your toughest sessions. Combined with lightweight contrast materials and fast-drying elastane panels, it delivers unparallelled airflow and long-lasting comfort. Flatlocked seams are strategically placed to prevent irritation, and reflective details offer added safety during dark runs. Lightweight, fast-drying, and naturally odor-resistant, this is a long sleeve that works with your body – not against it.
