They are made of 74% organic cotton, which is much more durable and flexible thanks to thicker fibers and special processing. It allows the skin to breathe and absorbs moisture well. The addition of polyamide (24%) makes the material more resistant to stretching and wrinkling. Children's socks have a dedicated 4F logo on the hem.  Multipack: 3 pairs per set. Children's cotton socks are made of stretchy material that fits snugly to the foot. Flat seams in the toe area increase comfort of use and prevent chafing. They have wide, elastic hems that hold the sock in place. Material: Cotton 76%, Polyamide 22%, Elastane 2%
