I wore jeans made from a mix of 47 denim and 70s denim for about 7 months.

Comparison with 01 Denim

The back pocket is 01 denim.

Summary

What differences did you feel?

My feeling is…
Comparing the colors, the 47 denim is a brighter blue, while the 70s denim is a duller blue.
The fading of the warp threads is more even on the 47 denim and more grainy on the 70s denim.
All the differences are slight, so the impression will change depending on the viewer.
