The Iron-ic Universe 1.0 men's long-sleeve shirt is a premium technical base layer engineered for versatile sports activities across all seasons. Crafted from an advanced blend of 39% polyester, 31% polyamide, 25% polypropylene, and 5% elastane, it ensures exceptional moisture-wicking directly from the skin along with rapid drying. Featuring EXPYRA LIGHT technology with a fabric weight of approximately 160 g/m², it delivers an optimal balance of thermal insulation and low weight, with the entire shirt weighing only around 180 g.

The sophisticated 3DN ADVANCE three-dimensional knitting system creates breathable micro-channels that accelerate air circulation in high-perspiration zones, maintaining an optimal body microclimate. The shirt performs exceptionally well in a wide temperature range from -5 °C to +20 °C, making it an essential piece of gear for hiking, trail running, cycling, or winter snow sports.

Uncompromised comfort is guaranteed by the anatomical seamless construction and the patented I-Band finish, which prevent chafing, pinching, or hem rolling during intense movement. A dependable compression fit supports muscles, reduces fatigue, and provides total freedom of movement, while the antibacterial nature of the fibers prevents unpleasant odors even after prolonged wear.
