Product Details

Partial lock increasing ventilation
Unzipping the partial zip during a run quickly increases airflow around the neck and chest area. Adjusting the opening allows for precise ventilation without the need to remove the long sleeve. During intense outdoor training sessions, body heating can be reduced in one movement, maintaining full concentration on movement.

Slim fit cut adapting to the body shape.
The streamlined slim fit line closely adheres to the body, accentuating the natural shape of the silhouette during dynamic exercises. The reduced amount of excess material minimises the feeling of looseness and prevents the clothing from shifting during quick changes in position. While running, the clothing stays in place, not restricting the range of motion of the arms or torso.

NB HEAT technology that retains heat
During training in low temperatures, NB HEAT technology focuses on retaining the heat generated by the body. The specialised function of this technology is to simultaneously protect against heat loss while effectively wicking moisture away from the skin's surface. Even during a demanding run on a cool day, the body remains warm and the skin dry throughout the activity.
Excellent quality
Very suitable for cold weather. It has a honeycomb interior, which in my opinion is the best for winter. And if you get sweaty, it doesn't get wet or cold.
