The Kilpi MAVORA TOP-M men's long sleeve thermal underwear is made from 100% Merino wool knit and is the ideal base layer for all outdoor activities, skiing or running when you need to stay dry, warm and comfortable. The Merino wool absorbs moisture well, wicking sweat to the surface to help maintain your comfort. A natural property of wool is that it can neutralise sweat, which eliminates unpleasant odours and naturally repels dirt. The MAVORA TOP-M T-shirt has a rounded collar and is sewn with flat seams that do not irritate the skin. There are two universal colours to choose from. For maximum functionality, we also recommend the Kilpi MAVORA BOTTOM-M thermal pants.
