Here is an IJIN selvedge style that has been around for some time now : style J5207. This is from the IRRGLR (irregular) line Kurabo 13 oz denim with lots of  “pops “, egg yolk stitch in 4 stitch sizes,white vitello label on left ( no logo )

This has a victorian backstrap ( sewn up into the waist ) & the infamous 6th pocket overlaid on the back ( with an halfman embroidery sewn in real indigo thread )
Real indigo thread is used on all seams/bar tacks that would be normally sewn in black……this is a key IJIN detail. The indigo obviously wears back in colour with the denim.

This model has inside military hanging loops & a ticking lined back yoke. The back crotch seam is the only seam sewn as a triple needle ( indestructible!). All IJIN actual selvedges are cut extra wide as you can see by the cuff.
