Aclima WarmWool Shorts Long with Windstopper for women are flexible and warm merino underpants. 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. The windproof material is less-elastic, so you may want to take a larger size than normally.
