What is Buffalo Systems?

Buffalo Systems is a Sheffield outdoor clothing maker founded by Hamish Hamilton, who developed its clothing with outdoorsmen, soldiers and mountain rescue teams. It has been making clothing in Sheffield since 1979.

Products and positioning

The brand is built on Hamilton's signature Double P System, which pairs a Pertex outer with a pile lining to create fast-drying, windproof and breathable garments. The range includes:

  • Jackets, shirts and smocks for men and women
  • Sweats, hoodies and T-shirts
  • Men's trousers
  • Accessories

Garments are made in small handmade batches in Sheffield, and the brand offers a repair service there.

Distribution

Buffalo Systems sells through its own website and through independent retailers that stock British-made outdoor and workwear clothing. Its head office and workshop are at The Old Dairy in Sheffield, with a design studio in the city centre.

Why it matters

Buffalo Systems is one of the few outdoor brands still manufacturing in the UK, and its Pertex and pile system remains a distinctive alternative to conventional layering.
