I've been wearing Net Positive for a while now and I'm not exaggerating when I say it's changed how I feel about what touches my skin every single day.
Let's get into why.
Wait, why does the fabric in your underwear even matter?
I used to think underwear was underwear. Then I started digging into what conventional bras and underwear are actually made of, and it kind of ruined cheap cotton-blend three-packs for me forever.
Most fast-fashion undergarments are made with synthetic fibers (hello, polyester and nylon) that are treated with a laundry list of chemical finishes to make them wrinkle-free, moisture-wicking, or stretchy. Some of what shows up in conventional intimates:
BPA and microplastics — yes, in your underwear, not just water bottles
Phthalates ("plastic softeners") — used to make synthetic fibers stretchy and soft
Azo dyes — synthetic dyes linked to skin irritation and, in some studies, broader health concerns
Formaldehyde-based finishes — used as wrinkle-resistant and anti-microbial treatments
Pesticide residue — from conventionally grown, non-organic cotton
PFAS-type "moisture-resistant" chemicals — the forever chemicals we're all trying to avoid now
Here's the part that gets me:
This fabric sits directly against some of the most absorbent, sensitive skin on your body, for hours a day, every day. Your skin doesn't just block everything out — it absorbs. And there's a growing body of research on endocrine-disrupting chemicals (things that can mess with your hormones) showing up in everyday synthetic textiles, which is a big part of why so many of us in the natural living space are paying closer attention to fabric choices for hormone health, skin health, and fertility.
I'm not a doctor and this isn't medical advice — but "fewer synthetic chemicals against my body all day" is an easy yes for me.
This is exactly why I started looking for a cleaner underwear brand in the first place, and why I landed on Net Positive.
What makes Net Positive different
Net Positive makes organic cotton and hemp undergarments that are actually certified — not just "eco" marketing language slapped on a tag. Here's what backs it up:
GOTS Certified
OEKO-TEX Standard 100
Azo Dye Free
This is the gold standard for organic textiles, covering everything from how the cotton is grown to how the final product is processed. It's one of the hardest certifications to get in the entire textile industry.
Every component of the garment, including the elastic and stitching (not just the fabric), is independently tested and certified safe against skin contact.
No synthetic azo dyes, which have been linked to skin irritation and other health concerns.
No Formaldehyde
None of the wrinkle-resistant chemical finishes that conventional brands rely on.
Organic Egyptian Cotton Association certified
"Economy of Love" certified
For their Egyptian cotton pieces, grown in nutrient-rich soil without pesticides.
Meaning the people making these pieces are treated fairly, with full supply chain transparency. That matters to me too.
Net Positive also sources their cotton from biodynamic farms that skip synthetic chemicals and fertilizers entirely, working with the land instead of against it — so the "clean" story starts at the soil, not just the finished product.
The pieces I actually own and wear
I'm not one to recommend a brand I haven't personally tried, so here's what's in my own drawer:
This is genuinely one of the comfiest bras I own, organic or not. No underwire digging in, no synthetic itch, just soft organic cotton and hemp that breathes. It's one of their bestsellers for a reason.
Soft, non-irritating, stays in place. If you've ever dealt with irritation from synthetic underwear (raise your hand, most of us have), this is the upgrade you didn't know you needed.
I'm currently living in this one. Soft, stretchy, easy nursing access, and I don't have to think twice about what's against my skin while I'm feeding my baby.
Comfortable through every stage, no digging waistband, and again — organic cotton against the skin during pregnancy just feels like a no-brainer to me.
