The KILPI WILLIE-J children's functional long sleeve T-shirt is the ideal bottom layer for sports or outdoor activities. The material with OPTI-DRY function perfectly wicks sweat and moisture away from the skin, is pleasantly warm, quick-drying and sufficiently elastic. In addition, mesh underarm inserts improve breathability and lighten the overall construction. Flat seams are gentle to the skin and do not irritate. The high collar is finished with a zipper. We offer Kilpi WILLIE-J in several modern color combinations for girls and boys.Material composition: 92% polyester, 8% elastane
