The New York Yankees have become the latest sports organization to partner with Sequel, an innovative women’s health and period care brand founded by former Stanford University athletes Amanda Calabrese and Greta Meyer. As part of the agreement, complimentary Sequel products will be available throughout Yankee Stadium, bringing menstrual health support into one of the most iconic venues in sport.
At first glance, it might seem like an unlikely pairing.
But by making period products freely available in a venue that welcomes roughly 1.5 million women each year, the Yankees are helping bring a conversation that has long sat on the sidelines of sport into the mainstream.
Across sport, there is growing recognition that creating more inclusive environments means addressing the practical barriers that can affect participation, comfort and confidence. Research from Australia recently found that nearly one in five girls aged 10-16 had considered dropping out of organized sport because of period-related challenges, highlighting how menstruation can influence long-term engagement in physical activity.
It’s a challenge Sequel was created to address.
“It was always our intent to support athletes that struggled with the same problems that we had, which was period products not being reliable when they needed to be,” said Calabrese in an interview with the Stanford Daily last year.
The company’s FDA-cleared “Spiral Tampon” was developed specifically with sport in mind. It reflects a broader belief that period care should be treated as essential equipment for athletes rather than simply another personal care product. Unlike traditional tampons, which typically use straight channels, it uses spiral grooves to create a longer path for fluid and promote more even absorption, with the aim of reducing leaks before the tampon is full.
Beyond Yankee Stadium, the company has partnered with other sport organizations including the Indiana Fever, Stanford Athletics and Major League Soccer, integrating products directly into locker rooms, training facilities and public venues. These partnerships are designed not just to build visibility, but to ensure athletes and fans have access to products when they need them.
But the company’s work doesn’t stop at the stadium gates.
Earlier this year, Sequel partnered with the Fever on “Period Pack,” a community initiative that brought players, staff and volunteers together to assemble 5,000 hygiene kits for distribution across central Indiana. The campaign raised awareness of menstrual equity while expanding access to essential products for those who need them most.
Conversations about accessibility in sport have often centered on facilities, programming and physical access. Increasingly, organizations are also recognizing how everyday experiences can shape whether someone feels able to participate. Something as simple as having access to period products can influence whether someone feels comfortable stepping onto a field, attending an event or staying engaged in sport.
The Yankees partnership reflects just how far that conversation has evolved.
Years ago, it would have been difficult to imagine a period care company partnering with one of the most recognizable brands in global sport. Today, that partnership is being positioned not as a niche initiative, but as a practical service for athletes and fans.
While sponsorship headlines typically focus on logos, signage and brand exposure, the Yankees and Sequel partnership points to another possibility: using the reach of sport to address barriers that have often gone overlooked. Making sport more inclusive doesn’t always require sweeping change. Sometimes it starts with meeting a basic need.
