Get to know us
We’re an activewear brand created by women, for women. Women who strength train, women who love to move. Women who take up space – physically, mentally, unapologetically. Because we believe every woman deserves to feel strong in her mind, body and spirit – and look amazing in the process!
Oner was created with the intention to Oner your body. We believe reaching your goals isn’t about doing just one thing well – it’s about integrating movement and support to build a stronger, more resilient body and mind. Our mission is to empower every woman to feel strong, confident and supported in activewear that celebrates both her power and femininity.
We envision a world where every woman feels empowered. By redefining what strength means, we support women to move with confidence, lift each other up, and Oner their full potential.
Krissy Cela founded Oner Active in 2020 after she became a personal trainer and struggled to find flattering activewear that combined empowering colours with performance properties. She began by customising her own leggings and creating her own designs, before quickly realising there was a gap in the market for products made by women, for women who lift – and want to look good doing so!

Everything we create is with you in mind – from the purposeful design details to our technical fabrics. Our pieces redefine strength and femininity, giving you versatile looks that move with you – from the gym to whatever’s next. Here’s how we make it happen.
Every style is meticulously designed and tested to ensure it’s fit for purpose. Our body-defining contour lines and cutaway details highlight the way your muscles move and contract. The reinforced scrunch-bum detail doesn’t just flatter your physique – it’s designed to move with you.
We believe in the power of colour – because when you look good, you feel good. Fact. Our custom ‘colour formula’ ensures you’ll always find a shade to suit you; plus, they’re easy to mix and match with your favourite Oner Active pieces.
Each style is made to help you perform your best, both in and out of the gym. Our expansive fabrics range and technical properties – from compressive to super stretchy, seamless to cut and sew, slouchy to sleek, sweat-wicking to breathable and 4-way stretch – give you multiple options for multiple activities. To find out more about how our fabrics are sourced, visit our Transparency page.
Every design is thoughtfully created, tested and perfected by Krissy Cela and our female-led Oner Active Product team. Oner Active proudly boasts an 87% female workforce, ensuring we genuinely represent you.
We’re not just an activewear brand. We actively bring to life our mission to make women stronger via our global community events, our athlete programme and our sponsorship of Project Power, inspiring young girls to move their bodies. Find out more in Who We’re For.
Our community comes first. The brand? That comes second. We want to bring women together to share unique experiences and foster a movement that extends far beyond fitness.

Whether we’re celebrating important cultural moments like US and UK Black History Month and International Women’s Day, or hosting an Oner Walk Club, we bring together our community to connect and share unique experiences.Our events and activations create real-life experiences that bring our mission to life. From small, intimate meet-ups to larger global initiatives, each one is designed to spark meaningful conversations and connections, in and out of the gym.

We’re also committed to shaping a better future through our sponsorship of Krissy Cela’s Project Power schools initiative (encouraging young girls to move) and by financially backing charities and cultural organisations that empower women in sports and promote inclusivity.
We believe in keeping things real with you. As a young and fast-growing company, we know we’re not perfect, but we’re committed to being as transparent as possible.
We’re constantly evolving – improving our processes, reducing our environmental impact, and making more responsible choices. We still have a way to go, but here’s what we’ve done so far.
We care about where and how our products are made. That’s why all our factories go through independent audits to ensure they meet globally recognised social and environmental standards. These audits cover everything from fair labour practices to workplace safety and environmental impact.
The organisations we work with for certification include Sedex, BSCI, Smeta, GRS, OCS, Oeko-Tex and SLCP.
At Oner, we’re serious about ethical production and human rights. We recognise modern slavery, including forced labour and human trafficking, is a global issue, and we’re committed to ensuring our supply chain upholds dignity and respect for everyone involved.
Beyond compliance, we also look for factory partners that go the extra mile – those that have initiatives in place to improve their workers’ lives.
Right now, we manufacture our garments in four countries:
Sustainability is a journey, and we’re taking steps – big and small – to make a difference. One of our main focuses is sourcing better materials, like organic cotton and recycled fabrics.
We also make sure all production samples from our head office are donated to organisations that can put them to good use.
Here’s what’s next:
We can’t wait to continue sharing our journey with you.

Based on our customer feedback and in close collaboration with our athletes, we have developed products which are true to size and perfectly fitted to the female body.
