West Ham United Women and Modibodi Announce Game-Changing Partnership to Champion Period Confidence in Sport

West Ham United Women have announced a groundbreaking partnership with Modibodi, the global leader in leak-proof apparel, who are teaming up with the Club as Official Back of Shorts and Period-Proof Underwear Partner.

In a powerful statement of purpose and progress, Modibodi becomes the first period-proof underwear brand to feature on-kit in women’s football — appearing on the back of West Ham United Women’s shorts throughout the Barclays Women’s Super League and domestic cup competitions.

This partnership unites two pioneering brands with a shared ambition: to break taboos, challenge conventions, and bring down the barriers to sport for women and girls.

Having led an industry move away from white to period-friendly colours, West Ham United take great pride in leading the challenging discussions on a variety of issues that affect athletes of all ages in women’s sport. Modibodi also believes that women should live their lives fearlessly to do all the things they love without fear of leaks holding them back. Modibodi’s aim is to inspire the 1 in 2 girls who avoid playing on their period, to play on.

Now, in partnership with Modibodi, the Club takes another bold step to drive change in women’s sport — on and off the pitch.

Together, Modibodi and West Ham United will celebrate what it means to play fearless. A limited-edition co-branded product range — developed in consultation with West Ham United Women players — will be released in the Club’s iconic Claret, Cerulean Blue, and Black. The range is designed to inspire confidence, normalise conversations around periods in sport, and encourage the 1 in 2 girls who avoid playing on their period to stay in the game. It will be available exclusively through Modibodi and official West Ham United retail channels.

Modibodi will gain prominent brand visibility through pitchside advertising, press backdrops, and across West Ham United’s digital platforms, amplifying the message that no one should be held back by their body.

Speaking on the partnership, West Ham United Head of Partnerships, Rebecca Rowley said:

From the the initial conversations with Modibodi, we have been truly inspired by their commitment to creating positive change and removing restraints that have long held back women and girls in sport. Coupled with their high-quality products, this partnership will drive true step-change in the industry, and we’re proud to provide a platform to amplify Modibodi’s message of empowerment, in football and beyond.

West Ham United Executive Director, Nathan Thompson added: “We are delighted to announce this first-of-a-kind partnership, which will see West Ham United Women become the first WSL team to have a period-proof underwear partner with an on-kit presence.

“This is a partnership we are extremely proud of. At West Ham United, we are always looking to create meaningful and impactful partnerships. By partnering with Modibodi, not only are we delivering an industry first, but we are finding an innovative way to support their goal to remove barriers to sport and exercise for women and girls.”

“This partnership is a powerful reminder that sport should be a place of possibility, not limitation. At Modibodi, we’re on a mission to ensure that no girl ever feels sidelined by her period. Partnering with West Ham United Women allows us to stand together and say: your body is not a barrier. Together, we’re inspiring a future where every girl can play with confidence, courage and pride — every single day of the month,” said Kerry Cusack, Executive Director, Modibodi
