Our Story

We stand for more than game-changing teamwear.

(But yeah, we do that too.)

How it Started

One Irish athlete. One American athlete. One big problem.

Hey — we're Grainne McGuire and Sophia Grego, co-founders of Kiana Sportswear. We met playing Gaelic football and Camogie in San Diego — and got frustrated with the same thing every season: women's teamwear wasn't actually made for women.

Real options for female athletes were scarce. Fits were sloppy. Designs were afterthoughts. So we decided to fix it.

Kiana comes from the Irish word Ceanna — meaning "same" or "equal." Because that's what we're here to do: level the playing field for women's sportswear.

We believe every female athlete — whether you're scoring the game-winner or showing up for your first practice — deserves gear that fits, performs, and makes you feel unstoppable.

Because why should the guys have all the best gear? Let's change the game.

Why This Matters

Women keep walking away from sport. The data is brutal.

Not because they don't love it. Because the system — the kit, the infrastructure, the way they're treated — was never built for them.

The problem isn't talent. It isn't grit. It's gear that wasn't built for women — and infrastructure that treats their sport as an afterthought. We're here to change that, one team at a time.

Our Mission

Better fit. Better function. Better gear that works as hard as you do.

What We Stand For

Five things we don't compromise on.

The principles behind every kit we ship.

01

Empowerment

Every woman's an athlete. We're here to make sure you feel like one — because confidence is everything.

02

Inclusivity

Bodies come in all shapes and sizes — and your sportswear should too. No one-size-fits-all nonsense.

03

Innovation

Old-school teamwear is outdated. We design better fits, better fabrics, and better performance gear for women.

04

Comfort

Gear so comfortable you forget you're wearing it. No pinching, no bunching — just movement that flows.

05

Integrity

We keep it real. No cutting corners, no compromises — just the best for female athletes. Always.
