In developing the Active F-Dry Light Long Sleeve Shirt, we focused on temperature regulation, sustainability, and comfort – the ideal base layer for mountain hikes or cool mornings when a bit more cold protection is needed. And if you happen to break a sweat, our sustainable ZeroScent technology effectively combats bacteria in the fabric with the help of natural silver ions, preventing the development of unpleasant odors without irritating the skin. Thanks to the innovative F-Dry technology, the material boasts the shortest drying time in our product range while feeling pleasantly soft against the skin. Another advantage: The shirt is primarily made from recycled polyester, making it environmentally friendly. This lightweight, versatile, and technically well-equipped Active F-Dry Light Base Layer is your ideal companion for an active summer season!.
