I have destroyed more items of leather clothing than I could ever count. Most of them are destroyed in the bedroom with my obliging wife, usually a jacket that gets ripped up during the fun. I have also ruined others in different ways including deliberately catching parts of jackets or jeans on sharp things so as to damage them. I have also used chemicals, (albeit very carefully) like toilet cleaner or battery acid to see what happens. Sometimes I get wet in a coat or jacket and then while still by the river/lake ect. just rip it apart and leave the remains for people to find. I have also gone for a walk in some local woods, wearing a jacket and during the walk I tear bits off and throw them on the ground, leaving a sort of trail behind me until I finally take off the tattered remains and throw them in a bush.
I have destroyed 4 pairs of leather trousers that my dad's ex used to own. I wore them in the bath and totally soaked them amongst many other things. It really used to turn me on seeing her wearing them after I had cummed on them and seeing feint stains and she had no idea. I also wrecked a leather skirt of hers. I have also ripped up several other pairs of leather trousers of my own.
