The Latest Trend in Your Work Wardrobe Stinks

Performance fabrics are moving out of the gym and into everyday clothes. Some men say that stinks.

The fabrics, usually a blend of polyester, spandex and other man-made fibres, have been a mainstay in workout gear for their sweat-wicking properties. Now apparel makers are using them for polo shirts, button-ups and suits. But a work day or wedding lasts a lot longer than a workout, giving the materials time to trap odours, cause breakouts and make you sweatier.

Tim Connon, a life insurance agent in Palmer, Tenn., got tired of adding a cup of baking soda to the wash to remove the mildew smell from his polyester-blend polo shirts, and eventually tossed them out. “It was ridiculous to have to take that extra step when the shirts shouldn’t smell in the first place,” he said.

Connon now wears only 100% cotton shirts, but said they are hard to find and more expensive. They also have to be ironed. “The performance shirts don’t wrinkle, but I couldn’t stand the smell and the itchiness of those fabrics,” the 31-year-old said.

Synthetic fibres repel water, which helps sweat evaporate but allows oil secretions from our bodies to build up on the fabric and trap odors, according to Renae Fossum, a senior director and research fellow at Procter & Gamble.

P&G has upgraded its detergents and introduced new products like Downy Rinse & Refresh, a fabric enhancer that works in the rinse cycle to strip away odours and residue that builds up on synthetic clothes. “We are trying to help consumers understand these issues are not in their head,” said Sammy Wang, a P&G senior scientist who specialises in fabric care.

Polyester is no stranger to friction. The fibre got its start in the 1930s lab of DuPont chemist Wallace Carothers. After Carothers got sidetracked by the discovery of nylon, British scientists picked up the thread and developed the first polyester fibre during World War II. DuPont bought the U.S. rights in 1946.

In the following decades, the fabric elbowed aside natural fibres like cotton, silk, linen and wool, thanks to its lower costs and easy care—you could throw it in the washing machine and let it drip-dry.

It was also suffocating, at least in its earlier forms. Wearing a 1970s polyester leisure suit was like “walking around in a Hefty bag,” said Alan Spielvogel, director of technical services at the National Cleaners Association, a dry cleaners trade group.

Clothing makers eventually added breathability, stretch, waterproofing and stain resistance. As athleisure took hold, polyester took off. Polyester surpassed cotton in 2002 and now outsells all other fibres, according to consulting firm Wood Mackenzie.

Covid further fuelled polyester’s growth as people got used to wearing more comfortable clothes while stuck at home.

Although women have adopted performance fabrics for dressier attire, men have been the primary driver of demand because they tend to put a higher value on features like stain and wrinkle resistance, said Kristen Classi-Zummo, an apparel analyst at market research firm Circana.

Dermatologists say that with the popularity of these fabrics, they are seeing a jump in “sweat acne,” which is caused by a yeast that lives on our skin that invades our pores when we perspire.

Erum Ilyas, a dermatologist in King of Prussia, Pa., said sweat acne is more prevalent with performance fabrics in casual or work attire than workout clothes. “When you work out, you usually rinse off afterward,” she said. “If you are wearing a shirt for 8 to 12 hours, you are stuck in that fabric for longer stretches of time.”

She tells patients to try using Head & Shoulders shampoo as a body wash to degrease the skin.

Tyler Cenname, the co-founder of a furniture company, purposely chose a dress shirt made of performance fabric to wear to a Las Vegas wedding in August because he thought it would keep him cooler.

“I actually sweated more than if I was wearing a cotton shirt,” the 24-year-old said. “And I broke out in a rash.”

Zach Klempf, the founder of an automotive software company, bought a moisture-wicking suit to keep him dry when presenting to clients and working trade show booths. He hadn’t counted on the suit absorbing cigar smoke during industry cocktail hours.

“I can’t wear it anymore, because the smell is so off-putting,” said the 32-year-old San Francisco resident. He’s gone back to wool suits.

Some performance-fabric fans say the odours are a small price to pay for the added comfort and absence of armpit stains. To combat the stink factor, some brands treat the fabrics with antimicrobial finishes.

That coating can wear off, according to Tony Anzovino, chief sourcing and merchandising officer at Haggar Clothing, which uses performance fabrics in 70% of its products. Instead, Haggar uses a type of polyester fiber that is spun into a longer yarn called a filament that makes it harder for microbes to attach.

Jonathan Poston, a 48-year-old consultant, who lives in Chapel Hill, N.C., wonders if we’re asking too much of our clothes. “In the tech world we call it feature creep,” he said. “The same thing is happening with clothes. They have to tick all these boxes.” He only wears 100% cotton shirts.

“As someone who has to wear a shirt for 14 hours a day, I don’t think it’s unreasonable to ask my clothes to do a lot,” said Ben Perkins, the co-founder of &Collar, a men’s clothing brand that uses performance fabrics. Nevertheless, Perkins plans to introduce a cotton-blend shirt after customers said they wanted one.

“You need to serve the synthetic majority and the cotton minority,” he said.

Luke Michel has already lived through two technology overhauls in his career, first desktop publishing in the 1980s and online publishing later on. But AI? He’s had enough.

So when his employer, the Dana-Farber Cancer Institute, made an early-retirement offer to some staff last year, the 68-year-old content strategist decided to speed up his exit. Before, he had expected to work a couple more years.

“The time and energy you have to devote to learning a whole new vocabulary and a whole new skill set, it wasn’t worth it,” he said.

It isn’t that he’s shunning artificial intelligence—he is learning Spanish with the help of Anthropic’s Claude. But, at this point, he’s less than eager to endure all the ways the technology promises to upend work.

“I just want to use it for my own purposes and not someone else’s,” he said.

After rising for decades and then hovering around 40% in the 2010s, the share of Americans over 55 years old in the workforce has slipped to 37.2%, the lowest level in more than 20 years.

The financial cushion of rising home equity and stock-market returns is driving some of the decline, economists and retirement advisers say.

But for some older professionals, money is only part of the equation.

They say they don’t want to spend the last years of their career going through the tumult of AI adoption, which has brought new tools, new expectations and a lot of uncertainty.

Many people retire when key elements of their work lives are disrupted at once, said Robert Laura , co-founder of the Retirement Coaches Association and an expert on the psychology of retirement.

“Maybe their autonomy is being challenged or changed, their friends are leaving the workplace, or they disagree with the company’s direction,” he said.

“When two or three of these things show up, that’s when people start to opt out.”

“AI is a big one,” he adds. “It disrupts their autonomy, their professionalism.”

Michel, whose work required overseeing and strategizing on website content, has been here before.

When desktop publishing arrived in the 1980s, he was a graphic designer using triangles and rubber cement.

The internet’s arrival changed everything again. Both developments required new skills, and he was energized by the challenge of learning alongside colleagues and peers.

It felt different this time around. “Your battery doesn’t hold a charge as long as it used to,” he said.

He would rather spend his energy volunteering, making art, going to operas and chairing the Council on Aging in North Andover, Mass., where he lives.

In an AARP survey last summer of 5,000 people 50 and over, 25% of those who planned to retire sooner than expected counted work stress and burnout as factors.

About half of those retired said they had left work at least partly because they had the financial security to do so.

In general, older Americans are less likely than younger counterparts to use AI, research shows.

About 30% of people from ages 30 to 49 said they used ChatGPT on the job, nearly double the share of those 50 and older, according to a 2025 Pew Research Center survey of more than 5,000 adults.

Baby boomers and members of Generation X also experienced the sharpest declines in confidence using AI technology, according to a ManpowerGroup survey of more than 13,900 workers in 19 countries.

“We as employers aren’t doing a good enough job saying (to older workers), we value the skills that you already have, so much so that we want to invest in you to help you do your job better,” says Becky Frankiewicz , ManpowerGroup’s chief strategy officer.

Jennifer Kerns’s misgivings about AI contributed to her departure last month from GitHub, where the 60-year-old worked as a program manager.

Coming from a family of artists, she said, it offends her that AI models train on the creative work of people who aren’t compensated for their intellectual property. And she worries about AI’s effect on people’s critical-thinking skills.

So she was dismayed when GitHub, a Microsoft-owned hosting service for software projects, began investing heavily in AI products and expecting employees to incorporate AI into much of their work. In employee-engagement surveys, the company had begun asking them to rate their AI usage on a scale of 1 to 5.

When it came time to write reports and reviews, colleagues would suggest that she use ChatGPT.

“I’d be like, ‘I have no idea how to use that and I have no interest in using AI to write anything for me,’” she said.

It would have been more prudent to work until she was closer to Medicare eligibility, she said. But by waiting until her children were out of college and some of her stock grants had vested, the math worked.

Her first act as a nonworking person: a solo trip to Scotland, where she took a darning workshop and learned how to repair sweaters.

“The opposite of AI,” she said.

Employers already under pressure to cut workers—such as in the tech industry—may welcome some of these retirements, said Gad Levanon , chief economist at Burning Glass Institute, which studies labor-market data.

“The more people retire, the fewer they have to let go,” he said.

Some of the savviest tech users are also balking at sticking around for the AI upheaval. Terry Grimm, who worked in IT for 40 years, retired from his senior software consultant role at 65 last May.

His firm had just been acquired by a bigger firm, which meant learning and integrating the parent company’s AI and other tech tools into his work.

Until then, Grimm expected he might work a couple more years, though he felt that he probably had enough saved to retire.

“I just got to the point where I was spending 40 hours at work and then 20 hours training and studying,” said Grimm, who has since moved with his wife from the Dallas area to a housing development on a golf course in El Dorado, Ark.

“I’m like, ‘I’ll let the younger guys do this.’”
