Terrarmar Mens Thermasilk Crew
100% Pure Silk Underwear. Natural, pure white, glossy, soft, incredibly light and warm. All Terramar® Thermasilks come with the EC2® Qwi k-DriTM Electrostatic process which has the ability to actually lift the moisture molecules away from the body and break them down for rapid evaporation. Since the EC2® Qwi k-DriTM process alters the molecular signature of the yarn in the fabric, the moisture control is permanent. It won't wash out or wear off. Limited quantity on women's XL scoop and pant.
