How Net Positive organic cotton and hemp underwear is made, from biodynamic farms to the Keyhole Bra, plus sizing, returns and current offers.
Key Takeaways
- The collection pairs breathable hemp with cotton from farms the brand says are Demeter certified.
- Four pieces make up the line, from $12 sale briefs to the $68 Seamless Bra.
- The Mid Rise Brief runs small, so Net Positive recommends sizing up before ordering.
- U.S. orders of $75 or more ship free; unworn returns are free for 30 days.
Net Positive makes women’s underwear and bras in three fabric collections: Organic Egyptian Cotton, Organic Ribbed, and Organic Cotton & Hemp. The last one leads the Featured Collections on the brand’s homepage, under the name “Healing Hemp.”
The idea is simple. Pair hemp, which the brand describes as breathable and moisture wicking, with organic cotton grown on biodynamic farms. The collection covers everyday briefs as well as bras, including the Keyhole Bra, one of the brand’s labeled best sellers.
Below, you’ll find what goes into the fabric, where the cotton comes from, and which pieces are worth a closer look.
Why Net Positive Started Making Cotton and Hemp Underwear
Net Positive began with a baby’s skin, not a fashion trend.
Founder Natalia Shevchenko says her daughter had severe eczema as a baby. Doctors suggested pills and steroids, but that didn’t feel right to her. Instead, she started researching fabrics and the chemicals hidden in everyday clothing. In her telling, once she switched her daughter to natural materials, the eczema cleared up.
That experience changed how she looked at her own wardrobe. If baby clothes sold as “organic” could still carry irritants, what about the underwear adults wear against their skin all day? When she checked, she says many brands marketed as “clean” still relied on harsh dyes, synthetic fabrics and chemical treatments.
So she built her own line: Net Positive.
Shevchenko, now a mom of two, moved to the U.S. from a small town in Russia with $500 and no English. She worked in investment banking and private equity before turning to wellness focused brands.
What Makes This Collection Different: Hemp Plus Biodynamic Cotton
Of Net Positive’s three fabric collections, this is the one named for two fibers. Each fiber comes with its own story.
What Net Positive Says Hemp Adds
Net Positive describes hemp as:
- Breathable
- Moisture wicking
- Naturally antibacterial and odor resistant
- Durable, and softer with every wash
The brand presents hemp as the fiber that helps you feel fresh through the day, while the cotton brings the softness.
The Cotton Side: Biodynamic, Not Just Organic
Net Positive says its cotton grows on biodynamic farms, each certified to the Demeter international biodynamic standard. The brand treats this as a step beyond organic. Here is how its sustainability page explains the difference:
| Category | Organic | Biodynamic |
| Soil fertility | Approved, imported fertilizers are allowed | Built on the farm with compost from rotating crops and livestock |
| Pest control | Certain organic pesticides are permitted | No pesticides; natural habitats and predator prey balance keep pests in check |
| Certification | Can cover a single crop or plot | Covers the entire farm |
The last row matters most. Under biodynamic rules, one field can’t earn certification on its own. The whole farm has to meet the standard.
On the cotton itself, Net Positive says it works with organic Egyptian cotton. The brand chose it because the growing climate produces longer fibers, which it says feel softer and hold up better to wear.
Where the Cotton Comes From
Net Positive’s cotton carries Economy of Love certification, a standard the brand ties to fair trade, full transparency and environmental justice.
The farms also sit inside a carbon credit system. According to the brand, each farm’s carbon footprint is calculated, with credit given for work like tree planting. The nonprofit Egyptian Biodynamic Association (EBDA) then sells those carbon credits to companies that want to offset their own emissions.
The key number: EBDA returns 80% of that carbon credit revenue to the farmers. Net Positive says this gives its partner farmers an extra source of income and a reason to keep farming sustainably.
What Net Positive Says Is Left Out
“Non toxic” is the reason many shoppers find Net Positive, so it helps to see exactly what the brand says it avoids. Its homepage lists six things its products are free of:
- BPA and microplastics
- Plastic softeners
- Harsh dyes and bleaches, replaced with low impact or plant based dyes
- Pesticides and chemical fertilizers
- Wrinkle softeners
- Moisture resistant chemicals
For the fine print, the “See the List” link on Net Positive’s fabrics page opens the 2025 AFIRM Restricted Substances List. AFIRM publishes this list for the apparel industry, and Net Positive uses it as the reference point for its “free from” claim.
Certifications back up the rest of the story, according to the brand. Net Positive lists GOTS certification, which it describes as covering organic textiles from seed to finished product. It also lists OEKO TEX Standard 100 for its trims and finishes, and says every component, including the elastic and stitching, is certified safe for skin.
The brand’s certification list also includes azo dye free and formaldehyde free.
The Net Positive Cotton and Hemp Essentials
This collection keeps things simple: two bras and two everyday underwear cuts, all in Net Positive’s organic cotton and hemp fabric. The Keyhole Bra is one of the brand’s labeled best sellers, and both underwear styles are currently $12, down from $20. Here’s a closer look at each piece, with prices as of September 28, 2026.
Keyhole Bra
The Keyhole Bra is one of the pieces labeled a best seller on Net Positive’s homepage. It is made in the brand’s organic cotton and hemp blend and built for everyday wear. It suits women with sensitive skin who want a soft, adjustable bra made without the harsh dyes and finishes the brand avoids.
- Organic cotton and hemp fabric, which Net Positive says is made with 96% plant based fibers
- GOTS certified organic cotton, with OEKO TEX certified components down to the trim
- Low impact dyes and no formaldehyde finishes, per the brand
- Adjustable straps and a multi hook band for a customized fit
- Double lined fabric designed to hold its shape wash after wash
Price: $52, in sizes XS to 3XL. U.S. orders of $75 or more ship free, so adding two matching briefs ($12 each on sale, down from $20) brings the order to $76 and qualifies. New customers can also get 15% off a first order by signing up for Net Positive’s emails. U.S. returns and exchanges are free.
Seamless Bra with Removable Pads
The Seamless Bra with Removable Pads is the only padded bra in Net Positive’s Organic Cotton & Hemp collection. It is wire free, with lightly lined triangle cups. It suits women who want a little more shape than a basic bralette but still prefer an adjustable fit and the brand’s plant based fabric.
- Organic cotton and hemp fabric, which Net Positive says is made with 96% plant based fibers
- Removable padding, so you can choose more structure or a softer, more natural feel
- Lightly lined triangle cups for gentle shape and smooth coverage, with no underwire
- Adjustable straps and band for a customized fit
- GOTS certified organic cotton with OEKO TEX certified components
Price: $68, in sizes XS to 3XL. The bra is currently on preorder, and Net Positive expects it to ship by November 1. Adding one matching brief ($12 on sale, down from $20) brings the order to $80, above the $75 threshold for free U.S. shipping. New customers can take 15% off a first order by signing up for Net Positive’s emails, and U.S. returns and exchanges are free.
Mid Rise Brief
The Mid Rise Brief is the most affordable way into Net Positive’s Organic Cotton & Hemp collection, and the brand describes its mid rise fit as its most loved. It is an everyday brief for women who want plant based underwear without synthetic fibers. One fit note from the brand itself: this style runs small, and Net Positive recommends sizing up.
- Organic cotton and hemp blend, which the brand describes as antibacterial and moisture wicking
- Mid rise fit with a gently lifted leg line
- Exposed elastic at the waist, designed for support that doesn’t dig in
- Made without pesticides, toxic dyes, or synthetic fibers, per Net Positive
Price: $12, down from $20 (40% off), in sizes XS to 3XL. Pairing two briefs with the $52 Keyhole Bra brings the order to $76, above the $75 threshold for free U.S. shipping. New customers can take 15% off a first order by signing up for Net Positive’s emails, and U.S. returns and exchanges are free.
Everyday Classic Fit Bikini
The Everyday Classic Fit Bikini is the hip height option in Net Positive’s Organic Cotton & Hemp collection, for women who want a classic bikini cut rather than a mid rise brief. It uses the same organic cotton and hemp fabric as the rest of the line, which the brand describes as soft, breathable, and gentle on sensitive skin. It comes in two colors, Mocha and Pink.
- Designed to sit comfortably at the hips with a smooth, no dig feel
- Classic bikini coverage, positioned by the brand as an everyday style
- Organic cotton and hemp blend, which Net Positive describes as breathable and moisture wicking
- Made without pesticides, toxic dyes, or harsh chemical finishes, per the brand
Price: $12, down from $20 (40% off), in sizes XS to 3XL. Three bikinis plus the $48 Raceback Bralette from the same collection come to $84, above the $75 threshold for free U.S. shipping. New customers can take 15% off a first order by signing up for Net Positive’s emails, and U.S. returns and exchanges are free.
How to Choose and Buy
A few details are worth knowing before you order, especially if you’re trying the collection for the first time.
- Check the size guide first. Every style in this collection comes in XS to 3XL, but fit varies by piece. Net Positive notes that the Mid Rise Brief runs small and recommends sizing up.
- Returns are free in the U.S. You have 30 days from delivery to return or exchange, with no return fees. Refunds go back to your original payment method.
- Keep items unworn and unwashed. The brand asks shoppers to wear their own underwear when trying pieces on, and it can refuse returns that show signs of wear.
- Returned underwear gets a second life. Net Positive says it donates all returned underwear to people in need.
- Shopping from outside the U.S.? International customers pay their own return shipping, and exchanges are available for U.S. orders only.
To start a return or exchange, use the returns portal linked from Net Positive’s Returns & Refund page.
Current Net Positive Offers
As of September 28, 2026, Net Positive is running a “National Clean Underwear Month” sale, with GOTS certified underwear starting at $12. In the Organic Cotton & Hemp collection, that includes the Mid Rise Brief and the Everyday Classic Fit Bikini, both marked down from $20.
Two standing offers also apply. New customers get 15% off a first order by signing up for the brand’s emails, and U.S. orders of $75 or more ship free.
The brand hasn’t listed an end date for the sale, so check current prices on Net Positive’s site before you order.
Is the Net Positive Cotton and Hemp Collection Right for You?
If fabric is the first thing you check, this collection was built with you in mind. Net Positive started when founder Natalia Shevchenko began questioning what her daughter’s clothes were made of, and that focus on materials runs through every piece.
The hemp brings the qualities the brand highlights most: breathability, moisture wicking, and softness that builds with each wash. The cotton comes from biodynamic farms that Net Positive says are Demeter certified across the whole farm, not just a single crop.
Not sure where to start? The Mid Rise Brief, at $12 on sale, is a low cost way to try the fabric. Explore the full collection on Net Positive’s site.
Summary
This guide covered the four pieces in Net Positive’s Organic Cotton & Hemp collection: the Keyhole Bra at $52, the Seamless Bra with Removable Pads at $68, and the Mid Rise Brief and Everyday Classic Fit Bikini, both on sale at $12, down from $20. As of September 28, 2026, the brand’s “National Clean Underwear Month” sale was running alongside 15% off a first order with email signup and free U.S. shipping on orders of $75 or more.
The Keyhole Bra stands out as one of the brand’s labeled best sellers, with adjustable straps and a multi hook band. The Seamless Bra is the collection’s only padded option, with removable pads and a preorder date the brand expects to ship by November 1. Behind all four pieces sits the same fabric story: hemp the brand describes as breathable and moisture wicking, paired with cotton from farms Net Positive says are Demeter certified.
Shoppers ordering the Mid Rise Brief should size up, since the brand notes that style runs small. Pairing the Keyhole Bra with two sale briefs brings an order to $76, just past the free shipping threshold, and U.S. buyers can return or exchange unworn items free within 30 days.
