What Our Gearhead(R) Experts Are Saying: "These tights are impressively warm without feeling bulky. I use them as a mid-layer on big mountain days, and they regulate temperature really well. The full side zips make them super easy to get on and off, even with boots on, and they've held up great against repeated use."Built for mountaineering and high-output cold-weather adventures, the Norr na trollveggen warmwool2 stretch Tights are the brand's warmest stretchy midlayer. They combine the thermal power of wool with the durability and moisture-wicking performance of synthetics, resulting in a layer that traps heat while still allowing airflow and quick drying. Naturally odor-resistant, the fabric keeps us feeling fresh even on multi-day expeditions. The slim-fit design follows the body's movements for climbing and technical activity, with articulated knees and a gusseted crotch ensuring freedom of motion. Details like full-length side zippers with color-coded pulls, an elastic waistband, and a secure thigh pocket add convenience for alpine missions. Whether worn under shells for winter expeditions or on their own in milder conditions, these tights excel in comfort, breathability, and warmth.
