LOL, I'm not surprised by their reply. This is what I'd expect tbh. In the end it's for the best as the environmental impact of these jackets, having them remade, etc is most certainly not worth it. Ask Shawn to send you some goat samples with your next order.This was their response:
Thanks for your email - we appreciate your concern regarding this matter,
please note that we use the same leather Buffalo on the Entire Jacket, i will send you the reference images of Buffalo skin shortly even the grain of above images is Buffalo leather,
I am not convinced that they mixed Buffalo and goat after all. From what I understand they may have mixed top grain with full grain though.
