I think someone posted on the 50$ wallet posting that the whiteish color is the natural veg. I'm going to guess that is the Cognac color then? It is definitely tough without the pictures.

I would like to get a wallet but I need to make sure I get the right colour. What is the colour of the wallet at the bottom of the description page? I would guess that it is natural tan. Thanks
The difference seems to be one less pocket on each side and the ability to customize your color. Personally, I like this better than the Saddleback one but, yeah, the price is more. This wallet is 140 on his etsy store so you are getting a little over 25% off here.
