The Sensor Merino Air men's long thermal bottoms represent an exceptionally lightweight base layer based on the exclusive Merino Air Knit fabric. With a density of 120 g/m², the material is designed for maximum breathability and superior thermoregulation, making these bottoms an ideal choice for high-intensity sports activities such as running, cycling, hiking, and ski touring.

The material composition consists of 90% premium merino wool and 10% polyamide silk, ensuring exceptional lightness, quick drying, and long garment durability. The fine natural fibers provide permanent antibacterial properties and effective protection against unpleasant odors during prolonged exertion, while the material maintains high comfort and moisture management.

For complete comfort during movement, they feature carefully crafted flat seams that prevent skin chafing, along with built-in UPF 25+ protection against solar UV rays. These bottoms combine minimal weight with the natural benefits of merino wool for optimal athletic performance in any weather.
