I have recently restarted playing the game and I wanted to reshuffle the gear to use some that I never pick up.
So I started giving myself items and materials and I noticed that cloth materials are all the same, the only difference being the color.
This makes it so that the geat Zak starts with ends being better than the Kanian cloth armor.

Is there some patch that fixes this ?

All cloth materials have the following stats:
Weight 1
Energy 3
Complexity 1
Durabilit 3
Armor 3.3
Damage 3.3.
