3D Evolution is one of the stories/inspirations behind Diesel Denim. They have a 3D look due to a certain way of stitching and that resin spoke about above. The resin gives the denim a shine and it almost looks like it pops out at you!
To find out if your pair is 3D Evolution you can open the zipper or button flies and it'll have a twisted stitched piece that says "3 D" vertically downward. I'll post a picture of an example!
The newest Thanaz in 888Q and 8880K are part of the 3D evolution pairs! Look earlier in this thread to see a picture comparison of those 2 that I did :)
