What is ISA bodywear?

ISA bodywear is the underwear label of Isa Sallmann AG, a family company based in Amriswil, Thurgau. The business traces its origins to 1849, and underwear has been produced in Amriswil for more than 170 years. Andreas Sallmann has led the company for over three decades.

Products and positioning

The range covers everyday underwear, sleepwear, loungewear and basics, with separate lines for men and women as well as children and babies. Men's products include boxers and pyjamas, while the women's range includes briefs, bodies and bustiers. Seasonal collections and special lines sit alongside the core basics; a collection in a Swiss wrestling inspired design proved a notable sales success.

ISA is one of the last Swiss underwear makers to knit its own fabric. Around 30 knitting machines operate at the Amriswil headquarters, and garments are sewn in Portugal.

Distribution

ISA sells through its own online shop, through Swiss retailers and online resellers, and through factory outlets in Amriswil, Uster and Ebnat-Kappel.

Why it matters

ISA is a rare example of vertically anchored textile production remaining in Switzerland, combining in-house knitting with a direct online channel and established wholesale partners.
