The men's Klimatex DASTY functional base layer set is designed for winter sports. The long sleeve T-shirt and pants are sewn with flat seams. The fabric does not contain elastane, the elasticity is achieved through the ribbed structure of the fabric. The material is breathable, quick-drying and sweat-wicking. The pants have an elasticised waistband, cuffs on the legs and a practical slit at the crotch.
