The two-layer construction of these bottoms for women is ideal for keeping you warm when temperatures plummet below freezing. Air gets trapped between the soft 100% cotton inner layer and the 65% cotton, 25% merino wool, 10% nylon outer layer, which creates a thermal barrier for maximum cold-weather protection. Machine wash and dry. Imported of U.S. material.

• Soft 100% cotton inner layer next to your skin
