Part of Sergio Tacchini's Archivio collection—celebrating classic designs from the brand's archive—the Rainer T-Shirt is made of pure cotton piqué for a premium fit and features an embroidered 'ST' monogram logo at the left chest. A striped crew-neck collar sports the Italian flag tricolor as a nod to the brand's roots, while rib-knit cuffs at the sleeves complete the look.
