Gear for
kids who
rise again.
Most kids' activewear is adult gear in a smaller size.
CoreFlex Shorts are engineered from the ground up — for how kids actually move, train, and live in their clothes.

Built from the sidelines.
Not the boardroom.
I'm Jesse — and I've spent years on the sidelines coaching and watching youth athletes.
Not watching trends. Watching what actually happens when kids play.
Shorts that ride up mid-drill. Fabrics that feel fine in the store, then lose shape by week three. Girls handed boys' designs in a different color and told that's their option.
Once you see it enough times, you can't unsee it.
Most kids' gear isn't designed for kids. It's adult product scaled down — built for cost, not for how a nine-year-old actually moves.
Sized down. Not designed down.
You've paid good money for kids' gear that quit performing by game three. That's because most of it started as adult product — just smaller. The fit, the movement, the function: all compromised.
Style over substance — every time.
Bright colors and bold graphics aren't performance. Your kid deserves real technical fabric — stretch, breathability, odor resistance — not just a look that fades after five washes.
The features that matter are missing.
4-way stretch. Real breathability. Odor control. UPF protection. These are standard in adult performance gear. In kids' gear, they're inconsistent at best — absent at worst.
They outgrow it before they wear it out.
Most brands sell you shorts, collect your money, and move on. We built the Growth Guarantee — because kids grow, and your investment shouldn't become a landfill item after one season.
Performance gear engineered from the ground up — for kids who keep going.
Most kids' gear is scaled down.
Eyrx is built for them.
Most kids' activewear isn't designed for how they actually move, wear, and live in it. Eyrx is engineered from the ground up. Here's what that changes.

It's not about the fall.
It's about the strength to rise again.
Eyrx is a premium kids activewear brand built from the ground up for youth athletes — not scaled down from adult gear. The name is rooted in resilience: the belief that strength isn't built in the winning, it's built in the rising. That's the kid this brand is made for.
CoreFlex Shorts are engineered specifically for how kids move, play, and live in their clothes. 4-way stretch for full range of motion. Breathable, odor-resistant fabric that holds up through practices, games, and everything in between. A kid-first fit built for youth bodies — not adult patterns in a smaller size.
Eyrx launched in 2026 with a single belief: kids deserve performance gear designed for them. Whether on the field, the court, or the playground — gear that keeps up, holds up, and was built for the way they actually play.
