Amazing! You have to try it! Review by Hang (Clark)
Absolutely love it, i've had it for a bit over half a year now and they are some of the fastest fading jeans i've ever had, great texture and they are super nice and soft! Can't believe the progress they're making, absolutely love them!!!! (Posted on 4/11/16)
Super hairy and super slubby!! Review by Niko Budyo
ONI surely spends a lot of time in producing the secret denim. This pair is unbelievable. You feel so comfortable wearing it eventhough it weighs 20 oz. At this price it is definitely a bargain! (Posted on 10/10/15)
my favourite cut in secret denim - pure class Review by Markus
If you know ONI, you know what you get: slubby, neppy texture and great workmanship. What can I say, this jeans does not disappoint. The cut is like the 512, which is roomy around the hip and tapered from the knee down. I love this cut like nothing else, I had the regular 512 before, but this one is a game changer for me. I find this cut to be very contemporary, if you are looking for a strong taper: this is the one for you.
Thanks to Denimio for great, great costumer service and the fastest delivery possible. Honestly, their parcels from Japan to Germany are faster delivered than some parcels within Germany. I am – as always – impressed :) (Posted on 10/7/15)
