We partnered with an Italian yarn spinner who is the only one able to create shades of this depth in the world to achieve the extraordinary smooth, soft texture and brilliant color of our mercerized heather basic socks. Made using two-ply mercerized Egyptian cotton staples, raw yarn is carefully passed through a low flame, where excess yarn "fuzz" is burned off. The yarn is then passed through a second phase of "top dyeing." The result is highly unique and luxurious sock. Also available in Men's Standard Fit (Sock Size 10-13) • Made in Italy • 80% Cotton 18% Nylon 2% Lycra • BTBLH3074C070
