Our Verdict

The SW1 wide trousers are a modern interpretation of a vintage US Army trouser. Made with soft but tough cotton twill, with a stylish and easy-going fit.

  • Materials: 11.2oz soft vibrant blue twill from Italian mill Berto, 100% cotton; copper-plated nickel buttons and rivets by YKK; Turkish 10oz twill pocket bags screen printed in North London
  • Fit: True to size. Very high rise waist which sits above the hips; fitted yet relaxed on the hips. Loose leg with ample room from thigh to hem.
  • Construction: Two-piece button fly with heritage shaping. Fishtail to back of waistband. Internal backing buttons for braces. Felled inside leg and crotch seams for strength. Riveted, bar-tacked stress points throughout to maximise durability. Chunky belt loops.
  • Made on Blackhorse Lane, London
  • Lifetime free repairs guarantee
