The problem with leather in modern cars is that it's "sealed". Look at the leather in your Wrangler and then look at a raw hide of leather. Notice how the leather in your Jeep almost appears as if it has a clear coat over it? Well, it has something of that sort, which is why the "conditioners" you see on the market will do nothing whatsoever for the leather in your Jeep.
The best (and only) real way you can maintain your leather because of this is to simply clean it regularly. Body seat slowly breaks down the leather over time, and all you need to clean it is something simple like this:
That's what I use, and I use it once or twice a week, wiping down all the leather.
Don't waste your money on any of the conditioners, as they don't work on modern sealed leather. That sort of stuff only works on raw leather basically.
