Thermore expands in the fashion sector

Thermore, a manufacturer of thermal insulation for clothing, is making inroads in the fashion industry. “We started out in the technical segment. Synthetic insulation was initially used in ski suits. As style evolved, fashion embraced technical materials, and today it represents the largest share of our business,” CEO Patrizio Lorenzo Siniscalchi tells FashionNetwork.com.

The company, founded in Milan by his father, Lucio, in 1972, has evolved into the sector’s first ingredient brand and today supplies down-free insulation to a wide range of fashion and luxury labels. Under the leadership of Siniscalchi Jr., it has strengthened its relationship with end consumers, who are increasingly discerning. “When we develop a new insulation product, we don’t think about our direct customer, but about the end user,” the CEO notes.

The latest collaboration is with Jaked, featuring Thermore insulation in the brand’s new outerwear collection for the Autumn/Winter 2025 season. The Impact Evo jackets, designed for racing, fitness, and sportswear, blend style and functionality, leveraging Ecodown Fibers Ocean technology, which is bluesign and OEKO-TEX certified.

Today, Thermore generates revenue of 13 million euros, with the US and Europe as its main markets. “Around 10% of sales come from Asia, primarily Korea and Japan. We have offices in New York and Tokyo. Around 90% of production is in the Far East, because insulated garments are manufactured there,” Siniscalchi continues.

On the pressing issue of the impact of fast fashion, “there needs to be a change. We must be more mindful of our consumption,” notes the CEO. “We do not use down, but recycled fibres from ocean-bound bottles, thereby helping to prevent the formation of massive plastic islands in the ocean. We have been investing in this for 40 years. We launched our first recycled product in the 1980s. At the beginning, it was difficult to find raw materials with the same quality as virgin polyester. Today, 98% of our insulation is made from recycled material. The chips used to make PET bottles are better than those used for fibres,” Siniscalchi concludes.
