A black turtleneck is Archer's preferred clothing item when on covert spy missions. He often takes credit for being the first to recognize its use as a tactical garment. During a rant Sterling nicknames it the "tactle-neck."
Archer has a closet full of $900 black turtlenecks woven from only the purest Azerbaijani cashmere wool. He bought 10 at once and charged them to ISIS. He told Woodhouse to sort them by color, because five are dark black and the other five are a slightly darker black. He is down one slightly darker black one because he ripped one on a duffel bag.
Whenever on a mission, Sterling always insists on wearing his turtlenecks. If a dangerous aspect of the mission comes up, he will even leave to go get one, as seen in "Skytanic." If he doesn't have the option of putting on a turtleneck, he loses some of his confidence in completing the mission. In "Jeu Monégasque" he said, "I mean come on I've broken into way tougher places, right? I mean not without my turtleneck, but still."ODIN agents are outfitted with turtlenecks as part of their uniform, which drives Archer crazy when seen.
- Archer has 5 Black and 5 Slightly-Darker-Black Turtlenecks.
- As seen in Blood Test, Archer's been wearing black turtlenecks since he was a child.
