It was race day for avid marathon runner, Debbie Mercer. She and her race pack got up early on a brisk winter's day in Chicago, Illinois, piling on warm layers over their compression tights, to run the Chicago Marathon.

Miles into the race, Mercer and her friends made a pit stop at the portable bathrooms. The female runners stood in long lines, awaiting their turns to do their business behind closed doors, while their male friends resorted to quickly and discreetly ducking behind the porta-potties, or finding nearby trees. Precious time ticked by as the women watched their male counterparts continue the race.

"I remember thinking 'I wish there was some way that we could do that too,'" Mercer recalls.

The Houstonian created Zip Hers, an activewear brand that has a full-length zipper lining the bikini area of each pant, to accommodate on-the-go women. The Zip Hers concept and design was intended to level the playing field for women and men when it comes to competitive sports.

"If we're wasting time on a bathroom break and they're not, that holds us back…Maybe it's our little tiny contribution to women's equality. We just really want to help women be the best that they can be," Mercer says.

From full-length pants and tights, to 3-inch compression or loose shorts, Zip Hers has established an array of products suitable active women. However, it was a long and winding road to producing such innovative, high-quality products that could be competitive in such a vast industry of activewear, according to Mercer.

Mercer kicked off prototype production in 2016. She jumped around to various designers and manufacturers, turning away samples that didn't quite fit her vision for the product. Part of the challenge, Mercer describes, was finding a manufacturer who could manipulate stretch and non-stretch fabric in high-quality ways. Maintaining maximum comfort and a sleek design were challenges when the new variable of a zipper was thrown into the mix.

"It took us a while to get the zipper design perfect so that it would fit well and have a design that was comfortable," Mercer says. "We had to find the right manufacturer to find the skill to make these. We found one in Dallas and one in Houston."

Through trial and error, the Zip Hers design team produced a smooth design that coexists seamlessly with the delicate areas that sit around the zipper. They created a custom-made zipper pull, an invisible, thin disk embossed with the Zip Hers logo.

"Women can easily grab it when they're squatting, and don't have to struggle to find it… you can't even tell that a zipper is there. It's very sleek," Mercer says. "They're all handmade. We have to have special fabric for the panels and…have to have special machines to get the seams just right."

By September 2019, the Zip Hers prototype was finalized and officially launched via the company's online retail site.

Zip Hers products, the first of their kind, are sure to change the game for female marathon runners, hikers and any other outdoor activity fanatics, Mercer says. With so many athletic brands available on the internet, Mercer hopes that Zip Hers' innovative approach to active wear, and the unique opportunity they offer to women, will help set the brand apart.

"We really don't see any other products out there like ours…As far as apparel goes, we're the only one," Mercer says.

Since launching last year, Zip Hers has watched their clientele expand with predominantly long distance runners and adventure goers. With the 'athleisure' trend on the rise, they're also seeing more women buying leisurewear for yoga classes, or indoor casual use. Mercer says that she hopes Zip Hers will continue to expand to reach female fishers, hunters, climbers, and even first responders, so that women never have to take off their duty belts.

From various race-day experiences of waiting in long bathroom lines as precious time ticks by, to when nature calls during outdoor activities involving co-ed company, Mercer confronted women's realities by proposing an empowering solution for women.

"Ultimately, it gives women a choice. What's more empowering for women than the power to choose what's best for them?" Mercer says.

fresh funding

Editor's note: This article has been updated to clarify information about Cart.com's investors.

Houston-based commerce and logistics platform Cart.com has raised $180 million in growth capital from private equity firm Springcoast Partners, pushing the startup past the $1 billion funding mark since its founding in 2020.

Cart.com says it will use the capital to scale its logistics network, expand AI capabilities and develop workflow automation tools.

“This investment will strengthen our balance sheet and provide us with the flexibility to accelerate our strategic priorities,” Omair Tariq, CEO of Cart.com, said in a news release. “We’ve built a platform that combines commerce software with a scaled logistics network, and we’re just getting started.”

In conjunction with the funding, Springcoast executive-in-residence Russell Klein has been appointed to Cart.com’s board of directors. Before joining Springcoast, he was chief commercial officer at Austin-based Commerce.com (Nasdaq: CMRC). Klein co-led Commerce.com’s IPO, led the company’s mergers-and-acquisitions strategy and played a key role in several funding rounds.

“The team at Cart.com has demonstrated excellence in their ability to scale efficiently while continuing to innovate,” Klein said. “I’m excited to join the board and support the company as it expands its AI-driven capabilities, deepens enterprise relationships, and further strengthens its position as a category-defining commerce and fulfillment platform.”

This is the income required to be a middle class earner in Houston in 2026

Cashing In

A new study tracking the upper and lower thresholds for middle class households across the nation's largest cities has revealed Houstonians need to make at least a grand more than last year to maintain their middle class status this year.

According to SmartAsset's just-released annual report, "What It Takes to Be Middle Class in America – 2026 Study," Houston households need to make anywhere from $42,907 to $128,722 to qualify as middle class earners this year.

Compared to 2025, Houstonians need to make $1,153 more per year to meet the minimum threshold for a middle class status, whereas the upper bound has stretched $3,448 higher. The median income for a Houston household in 2024 was $64,361, the study added.

SmartAsset's experts used 2024 Census Bureau median household income data for the 100 biggest U.S. cities and all 50 states and determined middle class income ranges by using a variation of Pew Research's definition of a middle class household, stating the salary range is "two-thirds to double the median U.S. salary."

In the report's ranking of the U.S. cities with the highest household incomes needed to maintain a middle class status, Houston ranked No. 80.

In the report's state-by-state comparison, Texas has the 24th highest middle class income range. Overall, Texas households need to make between $53,147 and $159,442 to be labeled "middle class" in 2026. For additional context, the median income for a Texas household in 2024 came out to $79,721.

"Often, the expectations that come with the term 'middle class' include reaching home ownership, raising kids, the comfort of modest emergency funds and retirement savings, and the occasional splurge or vacation," the report said. "And as the median household income varies widely across the U.S. depending on the local job market, housing market, infrastructure and other factors, so does swing the bounds on what constitutes a middle class income in America."

What it takes to be middle class elsewhere around Texas

Two Dallas-Fort Worth suburbs – Frisco and Plano – have some of the highest middle class income ranges in the country for 2026, SmartAsset found.

Frisco households need to make between $96,963 and $290,888 to qualify as middle class this year, which is the third-highest middle class income range nationwide.

Plano's middle class income range is the eighth highest nationally, with households needing to make between $77,267 and $231,802 for the designation.

Salary range needed to be a middle class earner in other Texas cities:

  • No. 28 – Austin: between $60,287 and $180,860
  • No. 40 – Irving: between $56,566 and $169,698
  • No. 44 – Fort Worth: between $55,002 and $165,006
  • No. 57 – Garland: between $50,531 and $151,594
  • No. 60 – Arlington: between $49,592 and $148,77
  • No. 61 – Dallas: between $49,549 and $148,646
  • No. 73 – Corpus Christi: between $44,645 and $133,934
  • No. 77 – San Antonio: between $44,117 and $132,352
  • No. 83 – Lubbock: between $41,573 and $124,720
  • No. 84 – Laredo: between $41,013 and $123,038
  • No. 89 – El Paso: between $39,955 and $119,864
