Massimo Osti

Massimo Osti founded C.P. Company in 1971 (originally named Chester Perry) and Stone Island in 1982, both of which became landmarks in Italian menswear and technical sportswear. He also contributed to the development of Boneville and earlier collaborations before establishing his own labels. C.P. Company and Stone Island remain active and influential brands today, though Osti himself passed away in 2005.

Massimo Osti pioneered numerous fabric technologies that transformed menswear, including garment dyeing techniques that gave clothing rich, uneven color tones, and the use of technical materials like nylon, rubber-coated cotton, and heat-reactive fabrics. His most famous innovations include the Stone Island Ice Jacket, which changed color with temperature, and Meta, a fabric made from vacuum-sealed metallic film. Osti held over 50 patents related to textile engineering and garment manufacturing.

The Stone Island compass sleeve badge, affixed to the left upper arm of most Stone Island garments, was introduced by Massimo Osti as a distinctive brand signature inspired by military insignia. The removable button-on badge reflects Osti's fascination with military and workwear aesthetics and the idea of clothing as functional equipment. It has become one of the most recognizable brand marks in menswear, particularly associated with football casual culture and contemporary streetwear.

Osti's design philosophy for Stone Island was built on treating garments as functional objects rather than purely fashion items, drawing heavily from military surplus, workwear, and outdoor performance gear. He believed fabric research should drive design, which led to experimentation with materials never before used in fashion, such as truck tarpaulins, Kevlar, and stainless steel mesh. This approach set Stone Island apart from traditional luxury menswear and established a template for what would later be called 'techwear.'
