As evidenced by your example, and that of a few others, the RIGHT kind of leather can be NATOfied with great effect.
Having said that, some crappy ones could give a novice the impression that ALL leather NATOs are atrocious.
I myself have a few, and find that Buffalo and Suede make for some of the nicest (= softest + resilient).
I remain amazed to this day that there are not more/better options available all over eBay.
I'd LOVE to get one in ostrich, like yours. Can ya PM me?
