Woven using sophisticated Fil d’ecosse cotton yarn which and then been further mercerised (a process that makes thread stronger and more silk-like) for an exceptionally smooth and fine gauge wearing experience, these Ralph Lauren Mercerized Cotton Flat Knit Plain Socks are superb dress socks that come in a multi-colour triple pack. The mercerising treatment also increases colour vibrancy so these men’s socks are deeply coloured, enhanced by contrast colour Polo Pony logo embroidery just below the cuffs.
