Jennifer Sey Wears XX-XY Athletics Shirt to Defend Women’s Sports – “It’s Just a Shirt” Viral Moment
In a brief but powerful 10-second video posted by Jennifer Sey, founder and CEO of XX-XY Athletics, the former elite gymnast and author walks through a busy event space wearing a black T-shirt featuring the brand’s distinctive green XX-XY logo. Surrounded by supporters in matching apparel, security personnel, and attendees, Sey captures the everyday reality of standing visibly for a straightforward principle: no men in women’s sports. The clip, which has drawn tens of thousands of views and strong engagement, pairs the simple visual of branded shirts with her clear message about protecting girls’ opportunities, fairness, and privacy in athletics.
1. Detailed Video Description
The video opens in a large indoor venue near a “Portal” entrance and escalators. Jennifer Sey, wearing a black XX-XY Athletics T-shirt with a bold green XX-XY graphic, a black baseball cap with the same logo, and a pink wristband, holds a smartphone and a Pepsi cup. She stands beside other women also dressed in the brand’s black-and-green shirts. In the background, people in purple shirts move through the space while security staff in suits observe the area.
As the camera moves, a Black woman in a matching XX-XY shirt and black scarf draped around her neck steps into closer view. She speaks directly to the camera with an expressive, slightly exasperated smile: “It’s unbelievable. All we’re doing is wearing shirts… supporting girls.” Sey appears alongside her, looking around the venue with a calm, slightly amused expression. The short clip captures the group simply existing in public while wearing the apparel that represents their stance. There is no confrontation shown—just the act of visibility in a crowded public setting, with the shirts themselves serving as the statement.
The production is handheld and authentic, filmed in real time at what appears to be a large organized event. The focus remains on the clothing, the faces of the women wearing it, and the contrast between the ordinary act of wearing a T-shirt and the reactions it can provoke.
3. Why This Video Is Worth Noticing
Jennifer Sey has become one of the most prominent voices advocating for sex-based categories in women’s sports. As founder of XX-XY Athletics—a brand created specifically to support fair competition for female athletes—she uses everyday visibility to normalize the position that biological males should not compete in female categories. The video underscores her core argument: stating “no men in women’s sports” is not extreme or provocative; it is a defense of opportunities, safety, and privacy for girls and women.
In an era when debates over transgender athletes in female sports continue to generate headlines, legal challenges, and policy changes across schools, colleges, and governing bodies, this short clip cuts through complexity. It shows ordinary people wearing clothing that affirms biological reality and female-only spaces. The reaction captured in the video—surprise that simply wearing the shirts draws attention—highlights how charged the issue remains. By choosing visibility over silence, Sey and her supporters aim to shift cultural norms and protect the integrity of women’s sports categories that were created precisely because of average physiological differences between the sexes.
The video resonates because it is short, human, and direct. It requires no lengthy explanation: the shirts say XX-XY, the women state they are supporting girls, and the message is clear.

It’s not a provocation. It’s just a shirt.
And yeah… I’m trying to make it normal to say no men in women’s sports. To protect girls’ opportunities and privacy.
If we’re not afraid to be visible, it moves the needle. And we’re not afraid.
