Customer Reviews

The most intensely slubby denim I've ever felt! Once I got over that aspect I was able to realize the true beauty of this fabric. The fat white vertical slub yarns look like heavy rain falling through a dark and thick fog. An effect created by the varying thickness of deep indigo warp yarns. The loose weave gives the fabric a nice textured feel. The fit chart on this site were spot on. I love these jeans so much I immediately put in an order for their 546zr "Secret Denim". I'm going to wear both pairs until they fall part completely, which will probably be a very long time. (Posted on 4/15/16)

Incredibly textured denim in a great cut Review by John M.
I love this denim texture! It's very similar to the PBJ AI jeans. Of course those have the unique color of the Tokushima hand dyed indigo and special stitching, but at 2.5 times the price.

The cut of these (like the 517s) is great because it's much slimmer than a regular but not skin tight. The waist does run smaller than tag size for the one wash, but with the loose weave it's very comfortable & will stretch out to fit just right.

A great value at the Denimio price. (Posted on 9/10/15)
Stunning Oni denim Review by William P.
Super denim, looks great and rough and stubby as you would expect from Oni, and a real patchwork of different colors and depths. Perfect size 34 and length works too. Its my 6th pair of Onis and they have never disappointed.

Service from Denimio was great, as usual. (Posted on 9/8/15)
