Dunlop's Silk Pro Tennis String is the closest the company has come to emulating natural gut-like feel. The string is made of of tiny filaments and polyurethane to provide outstanding power and touch. Silk Pro does a fine job reducing shock and increasing comfort, and the outer surface of the string has a new bonded polymer coating to make the string more durable. Silk Pro also works well in a hybrid string job to dampen a firmer feeling polyester string.
