So I'm a huge fan of leather, denim, and canvas goods. Primarily for the fact that you pay in advance (jeans might be 250 or jacket may be 800 but both will last for years) I myself enjoy watching something I live in and wear grow with me.

That being said, for leather quality you're going to look for things that are FULL GRAIN leather. It's the highest quality leather that I know. More like the highest grade. Different leather goods come in different leather qualities or grades as I like to call then. You have genuine leather which is basically saying there is just enough leather or leather particulate present for it to be considered "leather" this is cheaper more lower quality and not built to last. You have split hide or split leather which is where the layers of the hide are split so it'll feel more like leather but it's cheaper, lighter, and overall not as durable (however certain types of leather can only exist as split like from different animals). Then you have your latter end which is top grain, corrected grain, and as above full grain. Top grain is decent and affordable, i believe it just contains the top most layers of leather where the underside is split off (if I recall the by product would be suede), corrected grain meaning it could either be top grain or full but certain blemishes or unevenness have been lightly sanded to create a cohesive overall appearance. And then full grain which contains all layers of the hide in which one side will be the "rough out" and the other side will be smooth.

I will live and die recommending full grain leather. More often than not grandads leather jacket was probably full grain, pop's slick wingtip shoes? Probably full grain.

Also a tip I try to stand by when making a purchase of any kind is wording of the product description. If I'm selling you trash then I'm going to convince you that it's great. I'll use appealing words like "high quality" or "luxury leather". The way I see it, if I'm selling a good product and a high quality product and you're looking at buying... chances are you've learned or read about my product and don't need fancy words on my part to convince you of the quality of my product. Most jackets, jeans, and boots I've bought have rarely ever used embellishing words to hype up the product. They usually tend to just state what the article possesses and how it performs. Basically in my opinion expressing confidence in their own product.

Now for a leather jacket, I own a schott and a cockpitusa jacket and both of which are of magnificent quality and durability built to last me for years of adventures.
