Pure Blue Japan XX-18oz-013-WID Denim (Slim Tapered Fit)

Size Guide
Pure Blue Japan plunge the depths of the indigo ocean to bring you their latest 18oz double indigo slub denim!

Iwaya-san, AKA 'Indigo Yoda', founder and leader of PBJ, has been renowned for his innovation in indigo dyeing and highly textured denim garments. This latest release brings back a bestseller of the past and showcases the skill and knowledge of PBJ's 25-year history. The ultra slubby fabric has been slowly woven using vintage denim machines to create a truly 3-dimensional texture! Both the warp and weft have been grand indigo thread-dyed creating a deep indigo hue that looks almost black in brand new condition.

Unlike the traditional warp-only dyed denim, this pair will yield much higher contrast fading with electric-blue streaks! With time the ultra slubby texture will become even more beautiful with the dotted raised surface becoming brighter, and the lower areas remaining a deep indigo blue!

Heavy-duty chain stitching and roped belt loop construction have been used throughout for added durability! The riveted back pockets will also keep things secure for many years to come! The high-density veg-tanned deerskin patch will gradually soften with a rich patina like Japanese whiskey. Black-coated iron buttons and copper rivets will oxidise and chip away with wear and tear, revealing the silver colour underneath!

This fit is great for those who prefer a classic slim-tapered fit.

If you're looking for a truly unique pair of double indigo denim with ultra slubby texture and top-notch construction, PBJ's 18oz Double Indigo denim could be a perfect choice!

How We Measure

Pants and Shorts


With the major buttoned up (i.e. the top button) open the jeans and lay them flat, like shown. Measure from the front where the major button closes to the back belt loop. Double this measurement to find the waist measurement.

The way we measure the waist is different from the 'Side to Side' technique. If you are used to the 'side to side' technique you can roughly roughly downsize by 1 inch.

For example, 'side to side' measurement for The Flat Head 3002 waist is 28inch and using our method measures at 29.25inch.

Front Rise:

With the jeans lying flat measure from the crotch bar tack to the top of the waistband. 

Back Rise:

Spread out the crotch so the bar tack is visible, then measure from the crotch to the top of the waistband.


One inch down from the crotch, measure flat across to the other side.


Flatten the leg and measure along the inseam from the crotch to the leg hem. 

Leg Openning:

Measure straight across the hem from side to side.





Lay flat then measure from the shoulder's edge to the other shoulder's edge.


Lay shirt flat and measure from pit to pit.

Sleeve length:

With the sleeve flat measure from the shoulder to the cuff.

Arm hole openning:

Measure from the shoulder down to the pitt.

Vertical length:

With the shirt facing down, Measure from below the collar to the bottom hem.
