"What Our Gearhead® Experts Are Saying: ""These baselayer bottoms are my go-to for ski tours and shoulder-season hikes. They’re light enough that I don’t overheat, but the merino still keeps me warm when I’m resting. The flatlock seams make them comfortable under shells, and I love that they don’t stink after a couple of days out.""We count on the Smartwool Classic All-Season Merino Base Layer Bottom when days in the mountains call for lightweight warmth and reliable comfort. The blend of merino wool and nylon offers the best of both worlds: soft, natural insulation that wicks moisture and resists odor, plus the durability to keep up with rugged use. The athletic fit layers smoothly under shells and midlayers, while flatlock seams prevent chafing on high-output climbs. A merino-lined elastic waistband stays comfortable all day, whether we’re breaking trail in deep snow, setting up camp, or hiking through cool shoulder seasons. Lightweight, breathable, and versatile, these bottoms earn their spot in our year-round kit."
