Blue Blue Japan 'Oriental' Wool Jacket

Size Guide
Traditionally minded gears for the modern guys!

Here we’ve got an amazingly unique piece of outerwear for the cool seasons. Made using a specially developed ‘Kagozome’ flannel wool outer shell, the surface is smooth and has an irregular creased pattern!

With time, the indigo-dyed shell will age up to a lighter shade with some soft, soulful contrast.

Thanks to the Thinsulate lining, you’ll stay EXTRA warm throughout the day. The asymmetrical front closure is inspired by traditional Japanese garments which keep the wind out and gives off an irregular style!

If you want to experience the height of traditional outerwear craftsmanship with a modern design, this is it!

  • Shell: Japanese medium weight natural indigo over-dyed wool flannel
  • Lining: Thinsulate cotton lining
  • Large urea buttons
  • Twin front waist pockets
