This is my jacket! I just call it a patch jacket, don't really know what is supposed to designate one over the other (patch jacket or battle jacket). I like collecting patches so it's nice to show them off, like stickers. I also have a bag I bring to shows that I put patches on too.
A lot of these are from local bands, a couple I made by hand. there are some pins and patches that aren't music too.
I feel like punk patches tend to look way more DIY than metal, but both genres have really cool looking stuff! Always love seeing these at shows and stuff
