SUMMARY: MARO SHORTS GIVE YOU 10+ REASONS TO NEVER WEAR POLYESTER AGAIN
THE LABEL SAYS "PERFORMANCE." THE CHEMISTRY SAYS PETROLEUM.
1 / YOUR SHORTS ARE PLASTIC

THE LABEL SAYS "PERFORMANCE." THE CHEMISTRY SAYS PETROLEUM.

Most athletic shorts, including ones from premium brands, are 88 to 92 percent polyester. Polyester is plastic. It's made from petroleum, one of the cheapest raw materials on the planet, sold under performance-sounding names. Check the label on yours.

COTTON BREATHES. PLASTIC JUST HOLDS EVERYTHING IN.
2 / PLASTIC TRAPS HEAT

COTTON BREATHES. PLASTIC JUST HOLDS EVERYTHING IN.

Polyester sits against your skin and holds heat and moisture against it. The fiber does nothing to help your body regulate temperature. Organic cotton breathes the way your skin needs it to: air moves, moisture escapes, and your body does what it's supposed to do.

POLYESTER HOLDS ODOR AT THE FIBER LEVEL. WASHING DOESN'T FIX IT.
3 / YOU SMELL FASTER

POLYESTER HOLDS ODOR AT THE FIBER LEVEL. WASHING DOESN'T FIX IT.

Bacteria get stuck in synthetic fibers in a way washing can't fully clear. It's why athletic shorts smell within an hour of wearing them. Cotton doesn't hold odor the same way. MARO shorts stay fresh between wears.

YOUR PORES OPEN WHEN YOU SWEAT. PLASTIC FIBERS TAKE THE OPENING.
4 / MICROPLASTICS ARE GETTING IN

YOUR PORES OPEN WHEN YOU SWEAT. PLASTIC FIBERS TAKE THE OPENING.

When you exercise, your pores open. Microplastic fibers shed from polyester giving harmful chemicals them have a direct path. Every workout in synthetic fabric is an argument for what you're wearing against your skin.

Evidence: University of Birmingham Study

MOST "COTTON" SHORTS STILL HAVE A PLASTIC WAISTBAND.
5 / EVERY BRAND CHEATS ON THE WAISTBAND

MOST "COTTON" SHORTS STILL HAVE A PLASTIC WAISTBAND.

Brands use a phrase: "exclusive of trim." It lets them call their shorts cotton while the waistband, the part sitting against your skin all day, is still spandex and polyester. MARO's waistband is 60% organic cotton and 40% natural rubber. Nothing synthetic. Anywhere.

IT'S CHEAP TO MAKE. EXPENSIVE TO BUY. YOU'RE PAYING THE DIFFERENCE.
7 / WHY BRANDS KEEP USING POLYESTER

IT'S CHEAP TO MAKE. EXPENSIVE TO BUY. YOU'RE PAYING THE DIFFERENCE.

Polyester costs a fraction of what organic cotton costs to produce. The margin gets spent on marketing. The premium price on most athletic shorts is about the logo, not the material. MARO puts the money into what's actually touching your skin.

RESEARCHERS HAVE MEASURED WHAT POLYESTER DOES TO MALE HORMONES.
8 / TESTOSTERONE

RESEARCHERS HAVE MEASURED WHAT POLYESTER DOES TO MALE HORMONES.

Polyester contains chemical compounds that function as endocrine disruptors. Studies have documented their effect on testosterone levels and sperm quality in men who wear synthetic fabric against their skin. The chemicals absorb through skin. They're in contact all day. Organic Cotton carries none of those compounds.

PLASTIC FRAGMENTS ARE TURNING UP WHERE THEY SHOULDN'T.
9 / THE RESEARCH IS POINTING ONE WAY

PLASTIC FRAGMENTS ARE TURNING UP WHERE THEY SHOULDN'T.

Microplastic fragments from synthetic clothing have been found in blood, lung tissue, and reproductive organs. Switching what you wear against your skin is the simplest move you can make.

EXTREMELY COMFORTABLE, FITS AS ADVERTISED

It's more breathable than my cotton-blended or synthetic shorts, which makes it more comfortable to wear, and doesn't reek of body odor after a day of wearing it. It has deep pockets unlike some exercise shorts.

THE ONLY SHORTS YOU'LL EVER NEED

Lululemon who? Ditch the stretched out plastic and get these instead. Comfiest shorts I've ever owned. I'm a 32 waist and 5'11, bought a medium hoping for a short-ish fit and they're perfect. Quality is top notch and they look nice enough to wear for any occasion.

FAQS

Most brands get there through a loophole called "exclusive of trim." The main fabric is cotton, but the waistband is still spandex and polyester. MARO's waistband is 60% organic cotton and 40% natural rubber. Nothing synthetic. Anywhere.

Cotton is a durable natural fiber. With normal use and proper washing it holds its shape well. The advantage over polyester is that cotton doesn't permanently trap odor, so the shorts stay fresh longer without needing a wash after every wear.

Yes. The 2-inch outseam slit gives you a full range of motion. Cotton breathes better than polyester during activity, so you sweat less, not more.

The 5" sits above the knee on most builds and works for everyday wear and most workouts. The 7" has more coverage and suits taller guys or anyone who prefers a longer cut. The model on the site is 6'1" in a Medium.

No. The shorts are pre-shrunk. Wash cold and dry low heat and they'll hold their shape wash after wash.

S, M, L, XL, and XXL. Both the 5" and 7" inseam come in all five sizes.

Machine wash cold, dry low heat.

Returns and exchanges are easy. Reach out and we'll sort it.
