Patagonia is limiting the number of new customers it's branding its apparel for, choosing to work only with those that align with its environmentally conscious values.

A Patagonia representative said that while it had recently shifted its focus to companies that prioritize the planet, current customers in all industries could still work with it.

Business bros, be warned: A key part of your workplace attire is in jeopardy of going extinct.

Patagonia, whose fleece vests have become a staple of the "Midtown Uniform" (slacks, a dress shirt, and a vest), is no longer in the business of branding Wall Street.

The American clothing company recently decided to require new companies it works with to align with its values of being environmentally conscious and prioritizing the planet.

Patagonia's decision came to light on Monday when Binna Kim, the president of the public-relations company Vested, tweeted that Patagonia told her it was no longer producing branded vests for financial-services companies.

Kim told Business Insider that a certified reseller of Patagonia apparel making branded clothing for a client said it couldn't fulfill the order because Patagonia, which the reseller must get approval from, was focusing on co-branding with "a small collection of like-minded and brand aligned areas."

"Due to their environmental activism, they are reluctant to co-brand with oil, drilling, mining, dam construction, etc. companies that they view to be ecologically damaging," the reseller told Kim in an email, which she posted on Twitter. "This also includes any religious group/Churches, food groups, political affiliated companies/groups, financial institutions, and more."

A Patagonia representative told Business Insider via email that the corporate-sales program recently shifted its focus to work with "more mission-driven companies that prioritize the planet" and that the change affected only new customers, not existing ones.

Fleece zip-up vests have become a staple of the corporate world in recent years. The outfit has become so popular that it spawned an Instagram account, dubbed "Midtown Uniform," with over 112,000 followers.
