Founded in 2025, Onyx Sportswear was born from a single, powerful idea: that women's activewear should do more than just fit. It should transform.
We make activewear for the woman who refuses to settle. She trains hard, lives fully and wants gym clothes that honor both. At Onyx, we fused elegant design with premium performance to create something the industry had been missing: activewear that holds you in all the right places, moves with every rep and has you looking like the strongest version of yourself. Because when you feel confident, you become unstoppable.
Our Story
From day one, we've been driven by a singular vision: to create pieces that transform how women see themselves.
We didn't set out to build just another activewear brand. We set out to solve a real problem: why did women have to choose between clothes that look incredible and clothes that actually perform.
Onyx is the result of countless hours of testing, fitting, tweaking, and training until every piece feels exactly right. Elegant. Supportive. Seriously high-performing.
This isn't just activewear. This is what you reach for on the days you need to feel like the strongest version of yourself.
Our Mission
Most brands give you performance or style. We refused to choose.
Our mission is to design women's activewear that bridges the gap between elegance and performance, so you never have to sacrifice how you look for how you move, or the other way around.
Every piece we create is designed to shape, support, and empower you, whether you're mid-squat, post-gym, or living your life somewhere in between.
Our Vision
Every woman deserves to feel just as powerful stepping out the door as she does mid-workout.
Activewear that doesn't switch off when the workout does.
What Makes Us Different
Squat-tested, not just Instagram-tested
We didn't just make it look good in photos. Every piece gets squatted in, stretched in, and worn on repeat before it earns a spot in the line.
Color, not just black and grey
Most activewear drawers look the same. Ours doesn't. From Cherry Blush to Ice Blue, Onyx is built so your workout fits feel like actually feel like you.
From gym to everywhere else
You shouldn't have to change outfits between your workout and your day. Onyx is made to move with you through both, no second thought needed.
Our Values
01
Strength
Every body is capable of more than it believes. Onyx is built to move with you as you find that out.
02
Precision
No shortcuts, no filler. Every stitch, every seam, every color is considered — because the details are what make it feel right.
03
Confidence, Not Perfection
We don't design for a single body type. We design for the body you have, right now, moving forward.
04
Community
Onyx isn't built in isolation. It's shaped by the women who wear it, train in it, and push it further than we imagined.
