After the dust from the second presidential debate settled on Monday morning, it turned out that the real sartorial shocker of the night had not been Hillary Clinton’s Ralph Lauren pantsuit or Melania Trump’s pussy-bow Gucci top. It was a red cable-knit cotton sweater with a quarter zip worn by Kenneth Bone, audience member, undecided voter and overnight sensation.

An Izod product — simple, classic, all-American and quintessentially normcore — it went viral seemingly in minutes: a riposte, perhaps, to the more calculated looks on the candidates. “So You Want to Dress Like Presidential Debate Style Star Ken Bone,” read an Esquire headline. GQ offered, “We Found Where You Can Buy Ken Bone’s Presidential Debate Sweater.”

Several websites, including GQ, reported that the sweater sold out within hours. Izod quickly pointed out through its Twitter account that it was still available at Kohl’s for $48.99. Amazon restocked the item on Monday, but as of Tuesday morning, the red version appeared to have sold out again.

Not surprisingly, reviewers on Amazon seemed to be more excited about Mr. Bone than the sweater itself. “I was inspired by future President of the United States Ken Bone,” wrote Timothy Chippy, earning himself nearly 100 likes. “I love everything he stands for and that includes beautiful quarter zip red sweaters. #4yearsofsweaterweather.” Christopher C. Curtis wrote: “Some heroes wear capes. Others wear Izod Men’s Cable sweaters with a quarter length zipper.”
