Great fit \m/ Review by Fernando
The 546zr fits perfectly. Enough room in the thighs and the taper is just right. (Posted on 8/7/18)
Slub-tastic! Review by Brett
Slubs for miles. Jeans like this are a textbook case of being "rough" without being "coarse." Or maybe to put it better, rough without being abrasive. The weave is loose enough that they aren't oppressive, but have a fantastic heft to them.

The fit is just right for my thick thighs, but I'd avoid it if you're up above the "1.75x body weight squat" range.

And thank you, Denimio for great values, great site, and great shipping! (Posted on 8/18/16)
Great jeans! Review by Niro
I wanted to get my first pair of heavyweight jeans, and am so glad in choosing these Oni jeans! From comments on heavyweight jeans in general, I was expecting really rough and difficult to move in jeans, but I have had no such problem with these.

The fit for me is perfect. Slim fitting that is not tight anywhere, and sits perfectly on me. I am 5'10 with 32 inch waist, and bought the one wash version in tag size 31

If you like slubby and neppy jeans, then definitely give these a look.

Also, have to say that Denimio provided excellent service once again. They are easily my first choice.

Great jeans and fantastic service Review by kathryn
I love Denimio! Jeans arrived in the UK 4 days after purchasing. Beautiful denim (I got the one wash version). Looks better in real life, wuld recommend to anyone, a great and slightly unusual addition to any deamheads collection. Thanks (Posted on 10/7/15)
Awesome jeans with fast shipping at a low price Review by Jonathan J.
Got the jeans from Japan 3 days after I ordered them!
Gave the jeans 2 hot soaks and now they fit perfectly. Has a nice slubby texture and is a good fit for people that have slightly thicker thigh. Thanks Denimio! (Posted on 9/15/15)

Amazing product Review by Teun C.
These are some of the craziest fabrics I've ever seen.. The 20oz. secret denim is truly unreal. It offers a really nice mixture between slubs and neps, and with a very special and unique feeling texture... It seems a little rough on the outside, but it actually feels really nice to wear. The 20oz. quality feels nice and breathable, simply perfect for the appreciator of heavyweight materials! The Oni 546ZR offers a nice slim silhouette which will give a great fit when sized appropriate. For the denim-afficiando who is looking to get something truly unique in their rotation: Do not sleep on the secret denim from Oni...! When I first saw the fabric some years ago pictured on the internet I already fell in love with them, now that I felt them in person I feel like the pictures only do them half the justice. This is quality you have to experience yourself!

In conclusion: Great denim and a great fit, of course with some very nice detailing and loads of character! Next to the amazing jeans I would also like to thank Peter from the Customer Service for providing me with very accurate and timely responses.. Once again: Thank you, Peter! Also, nothing but love in general for the service Denimio offers... Shipped from Japan to Europe in just a couple of days, really nice!!! (Posted on 8/23/15)
Fantastic jeans, great service! Review by Michael
I just bought my second pair of Oni's from Deninio, and once again i can't rate the service help and advice highly enough. These fantastic denims arrived in just 3 days, from Japan to the UK!
The quality of these jeans is the usual great ONI standard, the cut is modern and quite slim,without being skinny and the denim itself is just wonderful, slubby as you would expect, but not feeling too heavy and difficult to wear.
Also i have to mention the service, Peter answered all my emails and requests and was so helpful and polite.
It's a pleasure to shop with such a great company, i'm already looking at my next purchase as i type! (Posted on 8/7/15)

Even though it is 20oz denim, it's not uncomfortable at all.
