That jacket as much a part of The Walking Dead universe as Rick’s revolver and Carl’s cowboy hat, but there’s a huge difference between a fictional character wearing it and a human being doing so, especially when the series films entirely on the outskirts of Atlanta, Georgia.
In Robert Kirkman’s Walking Dead comics, Negan’s signature look (as illustrated by Charlie Adler) centers wholly on the existence of a black leather jacket, which the villain wears almost exclusively for a long span of time.
Everybody knows how miserably hot it gets there, and while there are costume pieces that could lead to higher levels of sun-baked gloom, leather isn’t easily topped.
