Leather Plus Add-on 1.18

With the Leather Plus mod, leather will no longer be a useless material in Minecraft. Now you will be able to create new types of armor in the game with leather and normal materials. The armor will have the strength of the created material, but will get the functions of normal leather armor. This is quite handy because the new features in the game require leather armor in your inventory. So you'll be able to provide yourself with both protection and useful features.
