Step 1: check
history of retail wiki page. This one looks like it should be in era (page first created 2005). What's it make? Hmm, three pieces of gear that all have enchantments.
Step 2: check the
nasomi AH history. The cloth itself has rarely sold in singles, for crazy prices. Stacks have sold never. The gear has never sold.
So yeah, looks like it's disabled here; typically anything crafted with an enchantment effect on it is out of era or just disabled. The single sales of the cloth are a little strange, but maybe if one of the recipes was disabled for a while but not the other and eventually it was fixed, or something.
