This is a gorgeous bag. It has worn extremely well, the hardware is individually hallmarked with the Brahmin name and it fits huge amounts.
Pretty hard to find outside of the USA in my experience, but there are plenty of them on eBay.
I have taken pictures in different lighting so that you can see the different shades to best effect. It is not alligator but looks pretty like it. To the degree that I had a Brahmin backpack confiscated by customs here in Sweden as they thought it was the real thing.
