5 Reasons Your Leggings Might Be Disrupting Your Hormones
Your Last Blindspot
You Read Every Food Label. Have You Read Your Leggings?
Sarah thought she had her clean-living routine perfected. She bought organic products, used non-toxic cleaning supplies, and switched to clean skincare. But one morning she had a realization: "I switched to organic everything — except what's pressed against my body & skin for 8 hours a day."
Her leggings. Like most of us, she'd been living in them. Working, running errands, lounging, even sleeping. It turns out, what's in our leggings is just as important as what's in our food.
Why Your Leggings Might Be Disrupting Your Hormones
If you've meticulously cleaned up your diet and home, it's time to look at the clothes you live in. Here are 4 reasons your leggings might be working against your wellness goals.
The Synthetic Layer Is Touching Your Skin.
That buttery-soft feel of most popular leggings? It comes from polyester and nylon — petroleum-based plastic. Check the label on yours right now.
It likely says 80–88% synthetic. Even if yours says cotton — the other 37–45% is polyester and spandex, and it's the layer pressed against your skin. When you sweat, your pores open up, creating a direct pathway for the chemicals in those fabrics to reach your skin.
You wouldn't drink from a plastic water bottle left in a hot car. But you wrap your body in the same category of material and exercise in it for an hour.
The Chemicals Banned in Baby Toys Are in Your Leggings.
BPA and phthalates — the same chemicals you avoided in your baby's bottles and your food packaging — are used in textile manufacturing to make fabrics stretchy, wrinkle-free, and stain-resistant.
They're classified as endocrine disruptors, meaning they can interfere with your hormones. Fertility. Thyroid. Metabolism.
These chemicals don't just sit on the surface — friction and heat work them against your skin. Every workout. Every errand. Every time you sit in them for 8 hours.
Spandex for Stretch Is Pressed Directly Against Your Skin.
That four-way stretch you love? It comes from spandex — a synthetic polyurethane rubber. In every legging on the market, including the "organic cotton" ones, the spandex sits on the inner surface directly against your body.
You can't make leggings stretch without spandex. But you can change where it sits.
One method wraps the spandex inside the organic fiber so it never contacts your skin. You get the same stretch.
Most brands don't do this because it costs more to produce.
Your Moisturizer Is Regulated. Your Leggings Aren't.
Formaldehyde — a known carcinogen — is used in textile manufacturing to prevent wrinkles and mildew. It's banned in cosmetics. Restricted in children's clothing. But adult activewear? No testing required. The fabric against your skin for 8 hours a day has fewer safety standards than the moisturizer you wear for 2.
The Solution
Non-Toxic Leggings Without Plastic Touching Your Skin
We tested 14 organic cotton legging brands. All 14 still had spandex pressed directly against skin on the inner surface. The organic cotton was on the outside — for the label.
One construction method exists that reverses this. It's called PureWrap™. The spandex is wrapped inside the organic cotton and bamboo fiber so only natural material contacts your body.
Same four-way stretch. Zero synthetic skin contact. Made with OEKO-TEX certified materials, independently tested for 100+ harmful substances.

Frequently Asked Questions
What is PureWrap™?
PureWrap™ is our proprietary fabric construction. Instead of blending spandex directly into the surface that contacts your skin, we wrap the spandex fibers inside organic cotton and bamboo viscose fibers. This means you get the same four-way stretch and performance you expect, but with zero synthetic material touching your skin. It's the best of both worlds: performance and purity.
Are they really non-toxic?
Omana leggings are made with materials that are independently tested and OEKO-TEX Standard 100 certified — screening for over 100 harmful substances including BPA, phthalates, formaldehyde, and heavy metals. The fabric against your skin is a blend of GOTS-certified organic cotton and bamboo viscose. The small amount of spandex (10%) is encased within those fibers via PureWrap™ construction, so it never sits against your body.
What are the care instructions?
Machine wash cold on a gentle cycle with like colors. Use a mild, eco-friendly detergent. Hang dry or tumble dry on low heat. Do not bleach or iron. Proper care keeps the organic fibers and the PureWrap™ construction performing for years to come.
What is your return policy?
We offer a 60-day satisfaction guarantee. If you're not completely in love with your Omana leggings, you can return them within 60 days of delivery for a full refund.
How does the sizing run?
The leggings are designed for a true-to-size fit with a comfortable, supportive feel. We recommend ordering your usual size. Here's the size guide:
XS (0–2): Waist 24–25" | Hips 34–35"
S (4–6): Waist 26–27" | Hips 36–37"
M (8–10): Waist 28–29" | Hips 38–39"
L (12–14): Waist 30–31" | Hips 40–41"
XL (16): Waist 32–33" | Hips 42–43"
If you're between sizes, we recommend sizing up for a more relaxed fit or sizing down for a more compressive feel.
