Product Details

Long sleeve protecting against the cold
The long sleeve effectively protects the arms and forearms from the influx of cold air during intense movement. The extended sleeve design creates a barrier between the skin and the cool environment, limiting direct contact with low temperatures. When running in lower temperatures, the runner maintains a greater sense of warmth in their arms even with dynamic changes in pace.

Round neckline increasing freedom of movement
The tailored round neckline does not restrict arm movements during dynamic exercises. The absence of sharp edges around the neck eliminates the feeling of constriction when putting on and taking off the longsleeve. During intense running, the neckline maintains a stable position even with frequent changes in pace.

Material made from recycled polyester
The fabric made from recycled polyester and elastane allows for free movement even during the most demanding workouts. The structure of the material has been designed to enhance moisture wicking and speed up drying after intense effort. When you exercise with full focus, the awareness of using recycled materials adds value to every activity.
