From a small family business founded by four brothers in a small village in Italy in 1952, Gran Sasso has become an international icon with its true "Made in Italy" authenticity. The Di Stefano brothers' entrepreneurial spirit and passion for producing quality knitwear with elegance has helped the company establish a respected and consistent brand identity in both the local and international markets.

With the success achieved in the 1970s, Gran Sasso began building a large 36,000 square meter headquarters in 2002, combining production, warehousing, administration, showroom and dining areas. This structure was designed to accommodate more than 400 employees and the most modern machinery. Additionally, a new facility specializing in cotton fabric weaving was opened in Roseto degli Abruzzi.

Today, Gran Sasso is considered one of the leading companies in the production of swimwear and casual wear. Products are guaranteed of high quality with expert tailoring workmanship at every stage of production. Each product is handmade, making it special and distinguishable. In recent years, the third generation of the family has joined the company, continuing to maintain the balance between tradition and innovation. The company also has an industrial painting facility and showroom in via Montenapoleone, one of Milan's most stylish areas. You can access swimsuits produced by Gran Sasso easily and reliably with Germirli.
