Most leggings are designed to shape your body for photos.
Oya leggings were designed to protect your health and elevate performance β in real life.
After testing with over 100 medical professionals (OB/GYNs, dermatologists, and urologists), testing over 30 fabric combinations, and developing a patented moisture management system, Oya created leggings that do more than look supportive.
They are supportive.
And for many women, theyβve replaced everything else they used to rely on.
Your Skin Is Under Constant Attack (And You Can't Even See It)
β Standard leggings trap sweat and heat against your skin
β Harmful bacteria and fungi multiply in warm, dark, wet environments
β Over time, standard leggings can disrupt your skinβs microbiome, especially if theyβre made with toxic chemicals like BPAs and PFAs
Over time, this disrupts your skinβs microbiome. Thatβs when irritation turns into rashes, odor, yeast infections, bacterial vaginosis (BV), and urinary tract infections (UTIs).
β Up to 75% of women experience at least one yeast infection in their lifetime (Cleveland Clinic)
β High-sweat populations show increased levels of infection-linked bacteria (MDPI)
β Moisture-retaining textiles (like cotton) are known to disrupt skin health (PubMed)

Meaning, your body isnβt failing you.
Your leggings are.
The 15-Minute Sweat Test That Will Make You Rethink Everything
Put on a typical pair of leggings.Β
Move around. Workout. Sweat.
After just a few minutes, notice:
Heat builds up and the fabric traps sweat
Odor caused by sweat+ bacteria buildups during movement
Skin begins to feel damp, itchy, and irritated
Bad bacteria and yeast multiply
Your pH balance gets thrown off
That moisture has nowhere to go, because most leggings focus on appearance β not physiology.
Oya leggings have three discreet mesh ventilation channels β not see-through mesh, not marketing buzzwords β but real airflow pathways that allow heat and moisture to escape.
The result?
Your skin stays 1-2Β°F cooler, even during long wear or high heat. Women report feeling more supported during long days β whether theyβre training, traveling, standing, or chasing kids.
Thatβs the difference between fashion compression and engineered support.
Why That "Normal" Swamp Crotch Isn't Normal At All
Why Your Skin Stays Damp
Swamp crotch isnβt just about sweating β itβs about what your leggings do with that sweat. Some fabrics trap moisture. Others manage it. And that difference matters more than most women are ever told.
The vagina is a self-cleaning organ, meaning natural discharge is normal β and often increases with sweat, heat, and hormonal changes like puberty, pregnancy, postpartum, and peri-menopause (PMC).
When tight, moisture-trapping underwear or leggings donβt allow airflow or evaporation, that dampness stays pressed against warm skin. Over time, this can disrupt the vulvar and vaginal microbiome, creating conditions where yeast and bacteria are more likely to thrive (PBUK).
Thatβs why ventilation and fast-drying fabrics matter β not to stop what your body does naturally, but to let moisture escape so skin can stay cool, balanced, and healthy.
94% of our Oya wearers report drying faster post workout.
In a survey of 108 medical doctors, up to 94% reported improved post-workout sweat evaporation when wearing Oya bottoms.
The Irritation That Wonβt Quit
You know that feeling when you change your leggingsβ¦ and the irritation still doesnβt go away.
When the itching, dampness, or odor keeps coming back no matter how many products you try.
Thatβs not your body βbeing sensitiveβ β itβs your skin reacting to hours of trapped heat, sweat, friction, and chemicals in the one area that needs airflow the most.
Weβve normalized discomfort that shouldnβt exist.
Customer after customer tells us the same thing:
87% of customers report fewer infections and less skin irritation after switching to Oya
Those Infections And Rashes Aren't A Mystery
Research shows the vaginal and urinary microbiomes are closely connected and sensitive to changes in moisture, temperature, and airflow, with disruptions in the vaginal microbiome linked to urinary tract infection susceptibility (PubMed).
Moist, warm environments β like those created by tight, non-breathable fabrics β can make it easier for fungi such as Candida to thrive and for bacterial balance to shift, contributing to conditions associated with yeast infections and bacterial vaginosis (Apollo 24|7).
While leggings themselves donβt directly cause UTIs, BV, or yeast infections, garments that trap sweat and heat can contribute to conditions that increase the risk of these issues (Motherly).
The Skin Damage You Can't See (Yet)
When your pelvic area stays damp for hours, the damage isnβt always immediate β but it is happening.
Constant moisture and heat increase friction, weaken the skin barrier, and disrupt the vaginal and vulvar microbiome. This creates an ideal environment for irritation, odor-causing bacteria, yeast overgrowth, and inflammation β even if youβre showering regularly.
Now add fabrics treated with PFAS and BPA. These chemicals are commonly used in activewear and can be absorbed more easily through the skin when sweat and heat are present, contributing to hormone disruption and long-term health risks.
Swamp crotch isnβt just uncomfortable.
Itβs a sign your skin is under chronic stress.
βWeβve discovered many different chemicals that are used widely β such as perfluoroalkyl and polyfluoroalkyl substances (PFAS) and plastic-related chemicals like bisphenol A (BPA) β can all impact health and the health of future generations through endocrine-disrupting effects.β - NIEHS Director Rick W.

The Uncomfortable Truth: Your Most Sensitive Skin Is Exposed
The skin around your vulva is some of the most absorbent on your body.
If youβre careful about skincare, food, and hygiene β but ignore what touches that skin for 12+ hours a day β thereβs a gap in protection.
Oya exists to close that gap.
Chronic Irritation
Recurring discomfort, odor, and inflammation become normal
Decreased Fertility
Endocrine disruptors and repeated infections impact menstrual and egg health
Cumulative Exposure
PFAs donβt break down easily in the human body, so repeated skin contact builds up
Damaged Skin Barrier
Friction and moisture weaken the protective layer
Microbial Imbalance
Bacteria and yeast can multiply unchecked
"I recommend Oya to patients with recurring skin infections. The ventilation, absorption, and low-tox fabrics address the root causes."
- Dr. Sarah St. Louis, Board Certified OB/GYN
I bought every product I could get my hands on from OYA and I can honestly say that the products are worth the investment. Thank you OYA for the protection for me and my daughters.

What 3,000+ Protected Skin Barriers Are Saying
On the new Mom side of things, the leggings give me so much confidence to run. My pelvic floor is still weak and I'm going to physical therapy, but I've been nervous to run.. I just wanted to share since this is an entire brand that has built around athletic wear for women. If you guys are looking for a market that is completely untapped, it is postpartum mom's who are recovering and have weak pelvic floors.I really appreciate this brand and the confidence it's giving me!
I was finally able to wear leggings, sweat and not have a crotch odor! I would like to see higher waist. At the 45 to 55 age range there are a lot of us going through the hormonal changes and gaining extra umpf in our waists/abdomens.
I am very particular about my leggings, at 140 lbs 5 ft 3in a size small was the right fit! I was a bit weary at the fabric at first but they have quickly become my go to leggings. They are the whole package from tummy control, booty lift, no slouch, holds its shape even after continuous wear and NO white stretch out! If youβre questioning these, just buy it!β
IN LOVE with these! So comfortable to workout in, nice fit, lifts booty, and I feel dry and fresh down there! 5/5!

Your skin is your largest organ. Isn't it worth protecting?
Oya's leggings have three discreet mesh ventilation panels that act as a temperature regulators. These mesh panels are treated with special blends of plant extracts that will react to the temperature of your skin and regulate it effectively. The treatment absorbs body sweat and gives a cool sensation to your body. It reduces temperature by up 2Β°F, even during long wear or high heat.
The silver silver treatment on the mesh ventilation panels has undergone a comprehensive set of evaluations consistent with ISO and medical biocompatibility standards:
