Designed with the cross-country skier in mind, the UYN SPECTRE shirt features exclusive ISODOT technology to ensure the right level of warmth and ventilation at the same time. Micro-bearings integrated into the inner surface create an insulating airflow, special fibres transport sweat to the outside for a perfect body micro-climate whatever the conditions. When the activity is intense, the moisture produced by the body can escape through the micro-perforated back panel. Spectre stands out thanks to the HYPERMOTION construction of the shoulders and sleeves from a single piece of fabric. A technology exclusive to UYN that guarantees total freedom of movement for the arms and enhanced support for the muscles. The total absence of seams does not put limits to the high elasticity of the fabric and does not create uncomfortable constrictions during activity.
