Ma.Strum is the heritage from Massimo Ostis, the founder of CP Company and Stone Island.

The constant experimentation with fabrics, colors and patterns resulted in the launch of C.P Company, which was quickly followed by Stone Island.

Throughout the 1990s Osti worked with numerous different textiles, fabrics and styles, and those archive samples can today be seen in the result of Ma.Strum. All three brands offer a very unique and different style from the rest of the fashion market, and is hugely popular in its niche.
