It's an item specific to Solstheim. Like Michael said, you can kill the big floating Netches. They're relatively slow, but hit hard if they get close. Arrows from range aught to do the trick if you've got a decent Archery score or relative magical ability. You can also buy them from the merchants on Raven Rock. Other than that, random loot is the only way to get it, but Netch Leather won't appear in Skyrim proper, it's only going to appear on Solstheim.
Best Answer: PU leather is leather from the inner hide of the animal (usually a cow) because it's not the outer layer it has to be waterproofed with a polymer. So it is a real leather jacket, but like leather from a sun-burned cow that's peeled and you got the next layer down. On top of the PU leather is a finishing surface to give an external aspect like upper-layer leather. The inner layer gives the strength and suppleness, the outer layer gives the finish. It's the same leather that's used in most mid-range leather furniture. Hope that helps.
