Built from a 200 g/m² pure 18.4 micron merino wool knit, these slim-fit base layer tights deliver natural thermoregulation, moisture management, and odor resistance without relying on synthetic blends or chemical treatments. The next-to-skin fit is engineered for comfortable layering, with a hidden elastic waistband and low-profile seams positioned to minimize friction under outer layers. Suitable across all four seasons, they perform equally well under running tights on cool summer evenings as they do beneath shell pants for ski touring, snowshoeing, or ice climbing. The fully natural fiber construction makes them biodegradable and recyclable at end of life.
