Clean lines, athletic edge. The Slim-Fit Topstitch Tank Top is made from an 87% polyester, 13% spandex blend at 180 g/m² — lightweight, breathable, and with a four-way stretch that moves freely during any activity. The topstitch detailing adds a refined, technical finish, while the slim-fit silhouette and round neck keep it sharp and versatile. From the gym to the street.
