4FSkin thermal underwear – a second skin for trekking

This functional women's thermal underwear is designed as a first layer of clothing that effectively supports comfort during trekking, outdoor activities, and winter sports. 4FSkin technology molds the material to the body, creating a second-skin effect, allowing for complete freedom of movement without feeling constricted. A quick-drying finish efficiently wicks away moisture and helps keep you dry even during intense exertion.

The seamless construction minimizes the risk of chafing and irritation, making the underwear suitable for long-term use. The stand-up collar provides a comfortable finish that fits well under layers of clothing. The slim cut fits perfectly to the body without restricting natural movement.
