Everlane The Grade-A Cashmere Crew - NWT Color: Dark Navy Donegal This timeless style gets a luxe upgrade with the soft and lightweight warmth of cashmere. All cashmere fibers are hollow and made to trap warmth—like a polar bear's fur. Not all cashmere is equal, however. We source our Grade-A cashmere from Inner Mongolia, using only the longest (35 millimeter) and finest (15 micron) fibers to create garments that are durable, pill less, and get softer with wear. Materials Body: 100% Cashmere; Trimmings: 90% Cashmere, 9% Nylon, 1% Elastane Box 19/box105
