WarmWool Shorts Long with Windstopper are flexible and warm underpants for women. The fit is snug and the pants are knee-length. The front has a windproof material; perfect for training and activities requiring slightly more wind protection. Elastic waist is lined with wool for best comfort. Flat seams minimise the risk for irritation and chafing. WarmWool is a knitted material and thus elastic and flexible.
