These socks are made in the U.S.A. from certified organic cotton.  They come in a cream color (I call it dreamy cream) made from unbleached cotton, and a natural brown color.  The brown socks are made from Foxfibre® cotton, which is cotton that is grows naturally in earth tones.  The result is a rustic brown colored sock without the use of any dyes.  Both colors soften and deepen after washing.  These socks are a "medium" in terms of thickness, and are very soft and durable. Three-packs can be ordered all one color, or in a combination of the two colors.  Sizes small (7-9) through extra-large (13-15); cream only (no brown) in sizes small and extra-large.  85% certified organic cotton, 10% stretch nylon (outer foot), 5% elastic, rubber core covered with nylon (inner top).
