Panties with visible seams and edges are very unflattering under training clothes, especially shorts and leggings that are snug. We have therefore developed a seamless thong for ladies that is perfect for both everyday and training. The fabric in the panties consists of Italian nylon with a lined cotton wedge in the crotch that feels very comfortable against the abdomen. The thin and soft fabric makes the thongs virtually invisible under tight-fitting clothing. For the complete seamless underwear set, the thong can be combined with our seamless bralette .
