The World's Most Comfortable Thong® starts with the best materials. Each component was chosen for its specific stretch qualities, softness and fit. Also, 100% of the fabrics and trims used to make our Signature Lace thongs and panties are knitted in the USA. Even the Supima® cotton fibers used to make the lining are grown in the USA. Our Signature Lace is an exclusive pattern available only to Hanky Panky.
