The men's Kilpi MAVORA BOTTOM-M 100% Merino wool thermal underwear is the ideal base layer for all outdoor activities, skiing or cross-country skiing when you need to stay dry, warm and comfortable. The Merino wool absorbs moisture, wicks sweat to the surface, helping to keep maintain comfort. A natural property of wool is that it can neutralise sweat, thereby eliminating unpleasant odours and naturally repels dirt. The underwear with raised back protect your back from getting cold. Elasticated elastic at the waist does not press, adapts well and flat seam stitching does not irritate the skin. For maximum functionality, also consider the Kilpi MAVORA TOP-M long-sleeved thermal T-shirt.
