Stay warm and comfy during your cold-weather adventures with these Terramar Vertix tights. They're an \expedition-weight\ base layer, rated a 3.0 on their warmth scale (1=light, 4=heaviest), so they're perfect for seriously chilly days. Made from a soft, breathable fabric blend that feels great against your skin. The magic is in the ClimaSense technology – it helps regulate your temperature by adapting to your activity level and the outside weather, so you don't overheat or get too cold. Ideal for hiking, skiing, snowboarding, snowshoeing, hunting, or just as cozy winter lounge wear. They have a straight leg design. Sizing tip: they're meant to fit snugly as a base layer; if you prefer a more relaxed fit, consider sizing up. Easy care: machine wash cold and tumble dry low (hang drying is recommended for longest life). A reliable, high-performance layer from a trusted outdoor brand.
