The Kilpi WILLIE-M is a men's functional long-sleeved T-shirt that is an ideal base layer for sports or outdoor activities. The material with the OPTI-DRY function wicks sweat and moisture away from the skin, is pleasantly warm, quick-drying and sufficiently flexible. In addition, mesh inserts in the armpits improve breathability and lighten the overall construction. Flat seams are gentle 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. Material composition: 92% polyester, 8% elastane
