Nike sold out of its new Colin Kaepernick t-shirts just hours after they were released on Thursday.

The black long sleeve t-shirts, which were sold for $50 each, featured a Nike swoosh on each of its sleeves and the former athlete’s name in reflective lettering on the back.

A sleeve also read in small writing: "Believe in something even if it means sacrificing everything."

The release comes a month after the company captured headlines for the announcement of their endorsement deal with the athlete-turned-activist.

Share prices for the company performed at an all-time high last month after the company’s stock initially fell more than 3 percent following the announcement of the deal.

Though the signing of Kaepernick was greeted by many consumers with praise, the move also generated backlash from critics of the protest movement which the former San Francisco 49ers quarterback is at the center of.

Kaepernick was the first athlete to take a knee during the national anthem to protest racial injustice and police brutality.

"Just like the NFL, whose ratings have gone WAY DOWN, Nike is getting absolutely killed with anger and boycotts," the president tweeted shortly after the announcement of the deal.

Kaepernick remains a free agent who has not played an NFL game since the end of 2016 after becoming the face of the movement.
