The Patented Women’s Activewear Brand Built from Breast Health, Innovation &Purpose

Some brands begin with a trend.

SportPort Active began with a question:

How can women move safely, powerfully, and confidently in a world where technology now lives against the body?

For founder and inventor Kim Highfield, that question was deeply personal.

Kim’s relationship with health changed forever when her mother passed away from breast cancer when Kim was just 25 years old. Losing her mother so young reshaped the way she saw her body, her future, and the daily choices that support long-term wellness.

Kim had already been active in her late teens and early twenties—lifting weights, running, and staying fit—but after her mother’s passing, health became more than a lifestyle. It became a lifelong commitment. 

She began eating cleaner, training more intentionally, and reading everything she could about nutrition, exercise, disease prevention, and women’s health.

That pursuit of knowledge eventually became the foundation of SportPort Active.

The Moment That Sparked the Invention

In the early 2000s, cell phones became part of daily life. Women were no longer just carrying phones in handbags; they were running with them, commuting with them, and tucking them into the easiest available place during workouts: their sports bras.

Kim was doing it too.

As a runner, she understood the convenience. A sports bra felt like the obvious storage solution—until it didn’t.

Around that time, Kim began noticing medical articles and case reports discussing unusual tumor locations in young, otherwise healthy women. One case series published in 2013 described breast cancers in young women who reported prolonged direct contact between their breasts and cellular phones; importantly, case reports like these do not prove causation, but they did raise questions about a real behavior many women had adopted: carrying phones directly against breast tissue during daily life and exercise. 

That was the turning point.

Kim did not build SportPort Active from fear. She built it from awareness, precaution, and a refusal to ignore what women were actually doing.

A Careful Note on Cell Phones, EMF & Health

The science around cell phones and cancer is complex, and we believe women deserve honest, balanced information.

The National Cancer Institute states that cell phones emit radiofrequency radiation, a type of non-ionizing radiation, and that evidence to date suggests cell phone use does not cause brain or other cancers in humans. Although, the U.S. Food and Drug Administration (FDA) also states that the weight of scientific evidence has not linked cell phone radiofrequency radiation with health problems. Interesting enough, there is evidence in other countries were scientists link tumors to cellular radiation.

At the same time, the International Agency for Research on Cancer (IARC) classified radiofrequency electromagnetic fields as “possibly carcinogenic to humans” in 2011, noting that continued study was warranted.  More recently, a WHO-commissioned systematic review led by ARPANSA reported no association between mobile phone use and head cancers based on a large review of studies published from 1994 to 2022. The FDA has since passed a law that all cellular companies have to disclose the dangers around cellular use and are carcinogenic.

So where does SportPort Active stand?

We stand for choice, thoughtful design, and reducing direct exposure where women are already carrying devices against the body. Our patented technology is not a medical claim. It is a design solution—created for women who want a safer, more intentional way to carry their phones during movement.

Five Years of Research. Two Years of Prototypes. One Patented Solution.

SportPort Active did not appear overnight.

Kim spent years researching EMF shielding, garment construction, compression textiles, women’s anatomy, and athletic function. Early attempts failed. Prototypes were rebuilt. Pocket placement was refined. Fabric behavior was studied. Fit was tested under real motion.

The goal was never to simply “add a pocket.”

The goal was to engineer a pocket that was:

• Secure enough for running

• Functional enough for high-impact sports

• Comfortable enough for long wear

• Strategically shielded

• Beautiful enough to belong in luxury activewear

After nearly a decade of self-directed research and formal development, Kim turned the concept into protected innovation. SportPort Active notes that Kim Highfield holds two issued U.S. patents in women’s performance apparel: U.S. Patent No. 8,898,816, “Women’s Sports Top with Integrated Pocket Assembly,” and U.S. Patent No. 9,362,618, “Radio Frequency Shielded Clothing.” 

The radio frequency shielded clothing patent describes a garment pocket with an inner panel containing electrically conductive shielding designed to shield a portion of the wearer from radiofrequency energy related to an electronic device carried in the pocket. 

That is the heart of SportPort Active:

A real-world problem. A woman-led invention. A patented answer.

Why SportPort Active Exists

SportPort Active exists because women deserve activewear that is more intelligent than “cute.”

We believe your clothing should support how you actually move, train, sweat, carry, travel, and live.

That means designing sports bras and activewear with:

• Patented EMF-protective phone pockets

• Secure storage that does not bounce

• Compression that supports without suffocating

• Fabrics that retain shape

• Seams that prevent chafing

• Prints and silhouettes that feel elevated, feminine, and original

Our products are designed for active women who want performance, protection, beauty, and longevity in one garment.

Not one or the other.

All of it.

The Design Mind: Where Science Meets Art

Before Kim became an inventor, she trained as a visual artist.

That matters.

Because SportPort Active is not just engineered—it is authored.

Every garment begins with a design intention. Every print has lineage. A concept becomes a photograph. 

The photograph becomes a hand-painted oil painting. The painting is digitized onto premium technical compression fabric.

This creative process is as intentional as the patented technology behind the pocket.

At SportPort Active, beauty is not decoration. It is part of the engineering.

A garment must perform, but it must also inspire the woman wearing it.

That is why our collections often feel different from mass-market activewear. They are not built from templates. They are custom designed, tested, refined, and made with purpose.

Built for Athletes. Approved by Athletes.

SportPort Active garments are tested on real athletes before production.

That includes women who run, lift, practice yoga, train hard, and move through demanding routines. The goal is to ensure each garment performs under real pressure—not just in a photoshoot.

We test for:

• Phone pocket security

• Compression stability

• Strap placement

• Zipper comfort

• Seam durability

• Chafe points

• Sweat performance

• Long-wear comfort

If a garment shifts, rubs, stretches out, or distracts from movement, it is reworked.

That is why our fit process matters so deeply.

We are not designing for mannequins.

We are designing for women in motion.

Why Our Fabric Standards Are Different

SportPort Active is highly selective about fabric.

We use premium compression textiles because fabric quality determines how a garment performs after the first wear, the tenth wash, and the fiftieth workout.

Compression should hold.
Seams should stay flat.
Colors should not fade immediately.
Threads should not unravel.
Fabric should not bag out mid-session.

Our philosophy is simple:

If it cannot withstand movement, sweat, washing, and repetition, it does not belong in our line.

This is especially important for women ages 30–60, who are investing in activewear that must move from workouts to errands, travel, outdoor activity, and everyday life.

You are not buying disposable fashion.

You are investing in performance apparel built to last.

A Brand Born from Breast Health Awareness

SportPort Active will always be connected to breast health.

Not because we claim to prevent disease.

But because Kim’s story began with a mother, a daughter, and a life forever shaped by breast cancer.

That loss became a mission: to design activewear that honors women’s bodies, protects their comfort, and solves problems that were being overlooked.

The patented phone pocket became the first answer.

The broader brand became the continuation of that answer.

Every SportPort Active garment carries that DNA: health-conscious design, performance engineering, and feminine strength.

What We Believe

We believe women should not have to choose between beauty and function.

We believe activewear should be engineered, not guessed.

We believe health-conscious design can be elegant.

We believe pockets should be secure, not afterthoughts.

We believe compression should support—not punish.

We believe women deserve innovation created specifically for their bodies.

And we believe that one woman’s story can become a solution for many.

The SportPort Active Promise

SportPort Active is more than a women’s activewear brand.

It is the result of grief transformed into invention.
Concern transformed into research.
Research transformed into patents.
Patents transformed into garments women can wear.

Every stitch has intention.

Every pocket has purpose.

Every design carries the belief that women deserve more thoughtful options.

We exist for women who move with purpose, train with discipline, and care deeply about what they put on their bodies.

Because activewear should do more than fit.

It should serve you.

Final Thoughts

SportPort Active began with Kim Highfield’s personal loss, her devotion to wellness, and her determination to solve a problem women were facing in real time.

Nearly 15 years later, that mission is still at the center of everything we make.

We design for movement.
We design for confidence.
We design for protection.
We design for women who expect their activewear to work as hard as they do.

That is why SportPort Active exists.

And that is why we will always lead with purpose.
