  • Hooded parkas and shell jackets
  • Overshirts
  • Jersey and knitwear
  • Cargo trousers

Outerwear is the brand's best known category, made in coated, bonded and garment dyed technical fabrics. MA.STRUM sits at a premium price point and spans techwear, contemporary and workwear inspired styles.

Distribution

MA.STRUM is widely stocked by UK premium menswear and football casual retailers, sells through its own website and is also distributed in continental Europe.
