The story behind EYRX

A coach noticed.
A daughter made it personal.

Fifteen years ago, our founder coached a team sponsored by a major athletic brand. The “youth” gear arrived looking like smaller versions of adult clothing, made for boys. The girls felt like an afterthought.

Years later, seeing the same gap with his own daughter became the reason to start EYRX.

We spent more than a year working with talented designers to refine girls’ athletic shorts with her at the center of every decision.

Girls' Athletic Shorts Built for Every Sport She Plays

CoreFlex girls' shorts are cut for girls from the first pattern. Not a boys' short in a new color, and not an adult short in a smaller size. She can wear the same pair to school, recess, soccer practice and a Saturday tournament without spending the day pulling at them.

Built-In Liner. No Spandex Underneath.

Most girls who play end up wearing spandex under their shorts. Every CoreFlex girls' short has a built-in compression liner, so it is one layer to pull on. She stays covered through sprints, slides and stretching, and she is not tugging the hem down between drills.

Pockets That Actually Hold Her Phone

Deep side pockets plus a zip pocket for a phone or house key, and they stay put when she runs. Here is why real pockets matter in girls' athletic shorts.

How Long Are CoreFlex Girls' Shorts?

Inseams run 2 to 3.5 inches from XS to XL, with the liner giving coverage underneath. Measure her height, not her age, and check the chart in our guide to how long girls' athletic shorts should be.

Girls' Athletic Shorts FAQ

Do CoreFlex girls' shorts have a liner?

Yes. Every girls' style has a built-in compression liner, so she does not need separate spandex underneath.

Are they good for basketball?

Yes. The same four girls' styles are in our youth basketball shorts collection, built for open gym, practice and tournament weekends.

What if she is between sizes?

CoreFlex girls' shorts fit generously, so the smaller size is usually the better call. Go by her height, not her age.
