Slip into these soft, ultrawarm woolies before dipping a blade into the San Juan de Fuca or heading out on a tea-house trek through the Himalayas. Made from soft 6.9-oz merino wool with an extra-fine-gauge yarn and a durable jersey construction for a luxurious hand, these performance baselayer bottoms insulate even when wet, naturally resist odor, and stretch when you do. Brushed, branded elastic on the waistband is soft next to the skin. A gusseted crotch increases mobility and slims bulk beneath layers. We eco-wash our merino wool for softness and to reduce shrinkage without the use of environmentally harmful chlorine. Machine-wash cold; lay flat to dry.
