This Boglioli 16 micron wool jacket comes in black, navy and sand. In Boglioli's eponymous K-model, very relaxed construction and a beautiful, cashmere-like hand to the fabric. The micron is the diameter of the yarn. A human hair is generally 50-90 microns thick, so that gives you an idea of how fine a yarn this is. Runs true to size. Dress up or down. A perennial top seller!
