At first glance, this is a simple classic-style baselayer with long legs. However, for those who want to wear the same underwear on frosty days as well as on warm summer days, our "Sydney" underwear is an excellent choice. The unique fiber structure of merino wool provides insulation in the cold and cooling in the heat. It offers ideal thermal regulation for the leg area on the ski slopes under ski pants or in summer under softshell pants. In both cases, optimal performance of the natural fiber is guaranteed. The 200 g/m² fabric weight covers a wide temperature range, keeping you warm in icy winter temperatures and lightly cooling in late spring as the first warm summer days arrive. In all scenarios, the pants feel soft against the skin and do not irritate. No pinching, no chafing, no skin irritations. Flatlock seams, a gusset in the crotch, an elastic comfort waistband with a characteristic logo print as a subtle eye-catcher, and ergonomic cut are the foundation for a perfect first layer for climbing, speed hiking, trekking, or any movement-intensive activities. Excellent moisture management and temperature-regulating properties ensure a comfortable wearing experience. Whether directly on the slopes or during a break at one of the many mountain huts, the natural fiber always provides a balanced feeling of wear. The merino fiber is odor-neutral. On multi-day hikes, long periods of sitting while traveling, or overtime in the office, unpleasant odors are hardly absorbed. Odor-resistant, antibacterial, and easy to care for, the underwear can be hand-washed on a bivouac trip and can be worn for more than one day while maintaining a pleasant body climate.
