The Columbia Women's Omni-Heat Midweight Baselayer Leggings are another popular choice for women's synthetic base layer bottoms. These leggings are made with Columbia's Omni-Heat technology, which reflects your body heat back to you for added warmth. The leggings also feature a moisture-wicking fabric that keeps you dry and comfortable during physical activity. They have a midweight design that is perfect for layering under pants or wearing on their own. These leggings are great for outdoor activities in cold weather, such as skiing, snowboarding, or hiking.
