Literally Just Cheap Invisible Armor
That's what it is, literally just cheap invisible armor. Since the Cosmetic Armor Slots mod I use on Fabric lacks the option to toggle armor off, and I really don't want to make a competing cosmetic armor mod with that feature, this is a simple solution to that.
What does it do?
It adds invisible armor that can be made cheaply.
Specifically, the Cheap and Invisible set.
How to Craft?
I would, personally, just check JEI. That being said, the recipes are shown below. It's just normal armor recipes, but with sticks. Easy!
