The special fabric used to make the shirt combines the strengths of technical fibers with the naturally valuable properties of merino wool. The result is the most functional warm and snug base layer that works best when worn against the body in cold weather. The solid undershirt regulates temperature and is also suitable for use in leisure time.

In cold or changeable weather, the shirt stores body heat thanks to the merino wool and protects against the chill more effectively than simple polyester layers. A technical thread is carefully placed inside the fabric, which absorbs very little moisture. Thanks to this, the threading conducts sweat so that the fabric in contact with the body is dry and comfortable even during intense training.

Merino with an airy structure together with polyamide provides warmth even when it is wet outside and the base layer is damp. In very low temperatures, this shirt is suitable for use as a second, additional layer of clothing.
