Good one Review by Dima
Great modern fit. Extremely slubby fabric, which does not feel like 20 oz. I've got a pair of 15 oz Blaumann and 24 oz Samurai, Oni feels much closer to 15 oz.
Surprisingly as for Japanese brand, the size is much closer to usual European and American, so pay attention to size chart.
I have one critique - the back pockets are unlined.
Overall, there's not as much of investment in smallest details like I've seen with others, but I give it five stars because of practical fit and fabric specialty. (Posted on 12/7/17)
Can't stop touching mysel- I mean, the slubby texture. Review by Alex
While browsing Denimio's ONI selection, Peter started chatting with me via the customer service portal. I gave him the measurements of my RgT Stantons to see what he'd suggest for the closest fit, and we arrived at the relaxed taper fit. They arrived in 2 business days, and they fit like a glove. At 20oz, they are my heaviest pair of denim, and boy am I excited to face the cold Canadian winter with them. I shouldn't be surprised by the heft and slubby texture, being the owner of an Oni Secret Denim Type 3 Jacket, but I can't help but marvel at it nonetheless. Shoutout to Peter for making Denimio one of the best retailers in the industry. (Posted on 12/6/17)
