Ladies, leave your man at home.

The Wing was supposed to be the ultimate sanctuary for women: decidedly feminine in design, with walls and furniture in shades of millennial pink and a thermometer set at a women’s-clothing-friendly 72 degrees. Conference rooms and telephone booths are named after feminist icons like Anita Hill and fictional literary heroines such as Hermione Granger of “Harry Potter” fame. It offers perks that other co-working spaces can’t match — showers stocked with high-end beauty products and events featuring big names such as Rep. Alexandria Ocasio-Cortez.

Critics of the Wing were quick to point out the lack of diversity in the spaces, but the company’s expansion and popularity has brought up a completely different issue that was never expected to arise: straight men wanting to come in and hang out.

Sure, it’s not against the rules for men to be at the lady lair, which costs anywhere from $185 to $250 a month in the US to join. But that’s only because legally the company can’t ban men.

“There’s usually at least one [man] whenever I visit,” says Kaitlin Phillips, 29, a member in New York for the past two years. “It’s bizarre to choose to occupy a space women specifically wanted for themselves. Classic patriarchal entitlement complex.”

‘It’s getting worse. A guy even checked me out a few weeks ago.’

The problem, multiple members have told The Post, is that the men physically take up too much space with their bigger bodies and belongings. They hog the phone booths. And they aren’t respectful of some of the rules, ignoring the four-hour cap on guest visits and bringing in outside food. While they aren’t using the members-only changing rooms and showers (yet), they are in the guest bathrooms.

“At first it was jarring,” says a 30-year-old longtime New York member, who asked to not be named. “It started about a year ago and it’s getting worse. A guy even checked me out a few weeks ago. The whole purpose of the space is to not have to deal with anything like that.”

The Wing, which started with one location in New York in 2016 and has grown to nine locations in seven cities, including a new international outpost in London, never had a membership policy, because, reps say, they didn’t think they’d need one. Instead, they simply billed themselves as a women’s co-working space and social club.

This lack of official paperwork garnered the attention of the New York City Commission on Human Rights, which in 2018 opened an investigation into the company. The Wing’s large membership — more than 11,000 worldwide, according to reps — meant it couldn’t pass as a “social club,” and therefore can’t discriminate based on gender. This, coupled with a lawsuit brought by a 53-year-old man earlier this year claiming gender discrimination, led the Wing to formally adopt a membership policy: “The Wing is a space designed for women with a women’s-focused mission. Members and guests are welcome regardless of their perceived gender or gender identity. Recognizing that gender identity is not always consistent with someone’s sex assigned at birth, we do not ask members or guests to self-identify.”

Based on the new policy, the commission confirms to The Post that it dropped its investigation this past summer.

But all of the women The Post spoke to had the same questions: Why would a man want to go to the Wing, anyway? Just because he can? To hit on women? To be a troll? The company’s magazine is called No Man’s Land!

Phillips says she thinks the problem is new members — who may not be as familiar with the original purpose of the space — bringing in men as their guests.

“I think they’re just losers,” she says of the male plus-ones. “Or cucked boyfriends. It’s a legal fluke.”

Up until about a year or so ago, when the space was truly a women-only sanctuary, members said they could comfortably walk around braless in a robe after a shower. Now, they say, they’re constantly looking over their shoulders, wondering who the loud dude chewing his lunch is.

Numerous California members tell The Post that the phenomenon is getting out of hand.

“It’s just annoying,” says Caitlin White, a 31-year-old West Hollywood member who sees at least one man working in the space each day. “Why do men need to be there? Why can’t they respect the spirit of the place? Men have to have everything.”

The San Francisco location, numerous members tell The Post, “is really bad — like, filled with tech bros.”

“I usually see about five men coming in throughout the day,” says a 31-year-old San Francisco member who asked to remain anonymous. “I think it’s members bringing in men for investor meetings. Here, everyone is in [venture capital], and men still hold all the money and power. These women are trying to fund their businesses.”

When she first joined, she says, she made the mistake of bringing in her cis male boss for a meeting, something that she now regrets.

“I’ll never do that again,” she says. “He didn’t respect the space, acting like we were in a coffee shop or something. I was getting looks from other members.”

In New York, of course, the stares are no less subtle.

“I glare at the men and I glare at the members who bring them,” says the anonymous New York member.

White, meanwhile, says she hopes the company can work out some sort of happy medium.

“Maybe make it one day a week that men are allowed?” White says. “There has to be a legal way to work this out that still respects the space.”
