Kilpi WILLIE-M is a long-sleeved men's functional T-shirt that is an ideal base layer for sporting or outdoor activities. The OPTI-DRY material is a great way to remove sweat and moisture away from the skin, it is pleasantly warm, quick-drying and flexible. In addition, netted armpit inserts improve breathability and lighten the overall design. The flat seams are delicate on the skin and do not irritate. The high collar is finished with a zipper. We offer the Kilpi WILLIE-M in several modern colour combinations.
