Pure Blue Japan 18oz Double Indigo Type 3 Denim Jacket

Double indigo is the way to go for a modern, quality denim style.

The classic type 3 design makes up for a semi-casual feel with functionality as a priority.

This 18oz fabric is more un-even compared to the 14oz version and will age to a heavy contrasted look. Despite being a heavier oz, this 18oz denim is still soft to the touch and is flexible for comfy movements.

Matching nicely with the double indigo dyed fabric, the black coated silver hardware will age to a shiny, chipped look throughout time. A seriously cool, wabi-sabi look.

You can easily wear this one for a decade, a denim jacket like this is an item you can enjoy for a seriously long time!
