Ok skiers and snowboarders, hikers and mountaineers this one's for you. (Sized for Women. Men, see MSUTLS.) Perfect for warmth and breathability. You can dance and exercise all you want and this wicking silk helps balance moisture so you stay dry and comfortable. A good one for the tie-dye look with a bit of trim around the neckline and cuffed sleeves. These are light, underwear weight (75 grams/ sq. meter) 100% silk jersey knit, and are so light and soft, they are like a second skin. For athletes, they don't interfere with your movement or make you too hot the way thermals do. Also just a really luxurious smooth sleeping garment.
