Thermal shirt Air

The Long Sleeve Base Layer Air is a technical layer designed for intense training, lightweight as air but performing like a second skin. Thanks to the 37.5® technology integrated in the high sweat areas, the Long Sleeve Base Layer Air offers active thermal regulation that adapts to your pace and environment. Unlike traditional fabrics that wick moisture away, 37.5® uses naturally derived particles that extract moisture from the skin before it turns to sweat - keeping you dry and comfortable during your toughest sessions. Combined with lightweight contrasting materials and quick-drying elastane panels, it offers unparalleled air circulation and lasting comfort. Flat seams are strategically placed to avoid irritation, and reflective details provide extra safety during night runs. Light, quick-drying, and naturally odour-resistant, it's a base layer that works with your body - not against it.
