Most kids' gear was made by adult brands.

We only make one thing: gear for kids.

The Solution

Ultra-soft from the first wear. No convincing required.

UV protection, sweat-wicking, and odor control in every pair, every rep.

WHY KIDS CHOOSE EYRX

We started with the kid.
Then built the gear.

Most shorts are built to be bought. Eyrx is built to pass the drawer test — the moment your kid decides what actually gets worn.

Why Eyrx

Built from
the sidelines Not the
boardroom

"After seeing the same problem for years on the sidelines, I finally did something about it."

I spent years on the sidelines watching kids play in gear that wasn't built for them. Shorts that rode up mid-drill. Fabrics that quit after three washes. Once you see it enough times you can't unsee it. So I built Eyrx.

— Jesse, Founder of Eyrx
