The Blackwyrm Coat (ブラックウィルム・コート, Burakku Uirumu Kōto?) is a player-made black leather coat that Kirito wears in the final months of Sword Art Online. Kirito tends to wear this favourite coat of his even in the middle of summer, saying that he has become so used to it that he can't calm down without having it on. The coat is actually Kirito's 4th leather coat in the game, as he does have to occasionally upgrade his equipment. It was tailored from black dragon leather, a high grade raw material, by Aincrad's best player seamstress, Ashley. The coat provides the user with a high hiding bonus, allowing the user to hide from monsters or players that lack a high Searching skill.
