The LIGHT chassis in steam fit effectively transports moisture away from the skin. The undershirt and underpants with elastic at the waist are made of polyester that is soft against the skin and keeps the body warm, dry and comfortable during all types of physical activity. The channel-knitted fabric creates an air gap between the body and the garment, which increases the insulation. Material: 100% polyester, channel knitted, moisture transporting, 170g / m²
