Real results

Oya uses ISO-tested biocompatible fabrics free of BPAs, PFAS, Azo Dyes

Oya’s designs use cooling fabrics that keep skin an average of 5.2°F (2.9°C) cooler after hard exercise (Tastex testing), and discreet airflow channels that allow real ventilation.

Independent testing (MTS Lab, 2022) verified Oya is 2x more sweat wicking and 3x more breathable than competitor leggings

Traps Heat + Moisture

... against your skin, creating a warm, dark, wet environment where harmful bacteria and fungi can multiply. Over time, your skin microbiome becomes irritated — and that’s when rashes, infections, and irritation develop.

The numbers:

Up to 75% of women will have at least one yeast infection in their lifetime (Cleveland Clinic)
In athletic and high-sweat populations, skin microbiome studies show an increased presence of infection-linked bacteria (MDPI)
Textiles that absorb sweat and microbes (especially cotton) contribute to bacterial and fungal growth, disrupting skin health
(PubMed)
Apparel that limits airflow and retains moisture is a known risk factor for skin/soft-tissue infections (PubMed)

How Oya's Technology Works

All Oya bottoms and underwear are engineered with discreet airflow channels that are not see through. Instead, they allow real ventilation, not just "breathable" marketing.
Skin averaged 5.2°F (2.9°C) cooler after hard exercise (supplier testing)

A removable, absorbent pad fits seamlessly into the gusset of all Oya bottoms and undies to capture excess sweat and discharge, helping skin stay dry, balanced, and irritation-free.
Even during high heat or long wear.

Silver-treated fabric that controls odor-causing bacteria.
Antimicrobial performance tested through 100 washes.
The silver-treated mesh fabrics were tested to ISO 10993-5 (cytotoxicity), ISO 10993-10 (skin sensitization) and ISO 10993-23 (irritation), with no adverse response.

Standard "wicking" fabric = pulls away some sweat,

but most sweat stays trapped under the fabric

Oya's Patented Ventilation System =

Moisture evaporates and is absorbed by the insert instead of staying trapped

“I recommend Oya to patients dealing with recurring irritation. Ventilation, absorption and low-tox fabrics help keep skin drier.” — Dr. Sarah St. Louis, ABOG-certified OB/GYN and urogynecologist, Oya advisor.
