Made with second skin technology: A special cut based on the body, and the construction of the fabric with panels ensure a perfect fit, unrestricted freedom of movement and increased resistance to damage and deformation. The women’s T-shirt uses a reinforced four-fold flat seam made of Spider's Steel, which is up to 140% more abrasion-resistant than other fibres.

Lightweight and breathable: The thermal performance material has specially impregnated fibres that absorb sweat evenly and allow moisture to evaporate quickly even during intensive training or starts. It guarantees quick drying, even when completely submerged in water. The fabric in the sports functional shirt is dyed using an advanced nanoparticle sublimation process that makes the colours abrasion resistant and 40% more intense than conventional processes.
Hygienic and super comfortable: The fabric of our long-sleeved functional shirt contains silver ion fibres, which have bacteriostatic properties and effectively inhibit odours. Based on the anatomical structure of the female body, the shirt has a special ‘Fitcut’ cut that visually slims the figure in the waist. Airpanel ventilation zones in the form of mesh are used on the back and under the arms, which promote thermoregulation in areas with increased perspiration during activity.
