Most Father's Day gift guides look the same: a bottle of cologne, a generic grooming kit, a gift card, something that says “I ran out of ideas” more than “I thought of you.”
But if you’ve spent any time thinking about what goes into the products your family uses — what’s in your food, your skincare, your cleaning products — you already know the same scrutiny applies to clothing. Especially the basics. Especially underwear.
The truth is, most men’s essentials are made from synthetic fabrics treated with toxic dyes, BPA, microplastics, and chemical finishes that never appear on the label. And the clothing that sits closest to some of the body’s most hormonally sensitive areas is, more often than not, made from petroleum byproducts.
This Father’s Day, we wanted to do something different. We put together a guide to organic cotton brands for men that we genuinely believe in, brands built on the same values we bring to Net Positive: transparency, non-toxic materials, and the conviction that what touches your skin every day matters.
In this article, we’ll explore why organic cotton matters for men’s health, what to look for when choosing cleaner basics, and four brands we’d actually give to the men we love.
Why Organic Cotton Matters for Men's Health
We talk a lot about what women wear close to their skin. But men face many of the same risks from conventional and synthetic fabrics, and far fewer people are talking about it.
Conventional cotton is one of the most chemically intensive crops in the world. According to the Textile Exchange, conventional cotton farming accounts for approximately 16% of all insecticide use globally, despite covering only 2.4% of the world’s cropland. Those chemicals don’t disappear after harvest; residues can remain in finished fabric and come into contact with skin throughout the day.
Beyond the raw material, conventional dyeing and finishing processes introduce another category of concern. Azo dyes — widely used across the fashion industry- can break down into compounds researchers are studying for potential links to endocrine disruption. Formaldehyde-based finishing treatments, used to make fabric wrinkle-resistant and soft, are another area of ongoing scientific interest.
Research suggests that skin absorption of chemicals from clothing is a real and underappreciated exposure pathway. A 2019 study published in the journal Environment International found that dermal absorption can contribute meaningfully to total chemical body burden, particularly for compounds present in clothing worn for extended periods.
For men specifically, researchers are studying the potential connection between environmental chemical exposures and reproductive health. The underwear and basics worn closest to the body for 12 to 16 hours a day are worth thinking about.
Organic cotton, certified to GOTS (Global Organic Textile Standard) or OEKO-TEX standards, offers a measurably cleaner alternative. Grown without synthetic pesticides or fertilisers and processed without harmful chemical treatments, it significantly reduces unnecessary daily exposures.
What to Look for When Buying Organic Basics for Men
Not all “organic” claims are equal. The wellness industry, including fashion, has a well-documented greenwashing problem. Here’s what actually matters when evaluating a brand’s claims.
GOTS Certification is the gold standard for organic textiles. It covers the entire supply chain from fiber to finished product, including social and environmental criteria at every stage of manufacturing. A GOTS label isn’t self-reported — it’s independently verified.
OEKO-TEX Standard 100 tests finished textile products for harmful substances. It’s useful for ensuring the dyes, finishes, and processing chemicals used in a garment meet safety thresholds, even when the base fiber isn’t organic.
Fair Trade Certification speaks to how workers are treated throughout the supply chain. It helps ensure fair wages, safe working conditions, and community investment in the factories where products are made.
Transparency is harder to certify but easier to evaluate. Does the brand tell you where the fabric comes from? Who makes the products? What dyeing processes do they use? The brands with nothing to hide tend to share everything.
Our Father's Day Gift Guide: Four Organic Cotton Brands for Him
These are not sponsored recommendations. These are brands we researched, reached out to, and genuinely believe deserve a place in the wardrobes of health-conscious men.
NADS — Clean from the Inside Out
@nadsunder · nadsunder.com
NADS was founded on a premise that sounds simple but is surprisingly rare: men’s underwear should be made without chemicals that have no business being next to the body’s most sensitive tissue.
The brand makes certified organic cotton underwear that has been tested and verified to be free from BPA, azo dyes, phthalates, PFCs, formaldehyde, and heavy metals. It’s the kind of product that comes from founders who read the research and decided to do something about it.
NADS has developed a following among athletes, doctors, and biohackers who understand that what you wear is part of your overall health environment. For the performance-focused man in your life or simply the man who deserves better than what’s in a multipack from the drugstore, NADS is the answer.
Evan Kinori — The Kind of Pieces He Keeps Forever
@evankinori · evankinori.com
Evan Kinori is a San Francisco-based designer and pattern-maker who works with an intentionality that’s genuinely rare in fashion. Every piece in the current collection is made from organic cotton and hemp, cut and sewn without trend cycles, seasonal urgency, or the assumption that clothing is disposable.
This is slow fashion at its most considered. Fabrics are chosen for how they feel and how they last. Silhouettes are classic without being boring. And the whole ethos is built around making things worth keeping — the opposite of everything fast fashion represents.
For the man who already has everything and needs nothing except the one shirt he’ll reach for every morning, Evan Kinori is the answer.
Asket — Nothing Extra. Nothing Missing.
@asket · asket.com
Asket was founded in Stockholm in 2015 with a radical concept: one permanent collection of timeless essentials, crafted from natural fibers in Europe and improved obsessively over time. No new seasons. No trend collections. Just the best version of a t-shirt, a pair of trousers, or a classic shirt, made better year after year.
The brand publishes impact data, discloses factories, and prices transparently. In many ways, it’s the brand the fashion industry should have been building all along.
For the man who has decided to stop accumulating and start investing in what they wear, Asket is the answer.
MARO — Built to Last and Be Returned
@wearmaro · wearmaro.com
MARO makes natural clothing from organic cotton and merino wool — GOTS certified, plastic-free, and designed from the beginning with end-of-life in mind. When a MARO product is worn out, it can be returned to the brand to be repaired, recycled, or composted. Nothing goes to landfill.
It’s the rare brand that thinks beyond the point of purchase. For a man who cares about leaving things better than they found them, MARO is not just clothing — it’s a statement about how consumption can work differently.

Practical Takeaways: How to Gift More Intentionally This Father's Day
Shifting toward cleaner, more intentional gifting doesn’t have to be complicated. A few simple principles go a long way.
Start with the basics. Underwear, socks, and everyday t-shirts are worn closest to the skin and washed most frequently, making them the highest-exposure category in any wardrobe. If you’re going to make one change, start there.
Look for third-party certification rather than marketing language. “Natural,” “eco-friendly,” and “sustainable” are not regulated terms. GOTS, OEKO-TEX, and Fair Trade are independently verified.
Think about longevity over novelty. The brands in this guide aren’t built around newness. They’re built around lasting. A well-made organic cotton t-shirt that holds up for five years is a better environmental and economic choice than three conventional ones that don’t.
And finally, share what you know. The men in our lives are often the last to think about this stuff. A thoughtful gift with a short note explaining why you chose it can be the beginning of a longer conversation about health-first living.
Conclusion
Father’s Day is an opportunity to give something that actually means something — not because of the price tag, but because of the thought behind it.
The best organic cotton gifts for dad reflect the same values you bring to your own daily choices: non-toxic materials, transparent sourcing, and the belief that what touches your skin every day matters. The four brands in this guide — NADS, Evan Kinori, Asket, and MARO — are all building something worth supporting.

Frequently Asked Questions
Why does organic cotton matter for men's health? Conventional cotton and synthetic fabrics can contain residual pesticides, azo dyes, and chemical finishing treatments that come into contact with skin throughout the day. Researchers are studying potential links between prolonged chemical exposure through clothing and endocrine disruption. Organic cotton certified to GOTS or OEKO-TEX standards is grown and processed without these chemicals, reducing unnecessary daily exposure.
What is the difference between GOTS-certified and OEKO-TEX-certified? GOTS (Global Organic Textile Standard) certifies the entire supply chain from raw fiber to finished product, including environmental and social criteria. OEKO-TEX Standard 100 tests finished textile products for harmful substances regardless of whether the base fiber is organic. Both are independently verified. GOTS is generally considered the more comprehensive standard for organic claims.
Is organic cotton underwear actually better for you? Research suggests that skin absorption from clothing is a meaningful exposure pathway, particularly for garments worn for extended periods close to sensitive skin. While no clothing can claim to be a health product, choosing organic cotton over synthetics reduces the number of chemical inputs your body is exposed to daily. For many health-conscious consumers, it’s a simple, meaningful swap.
Are these brands available to ship internationally? All four brands in this guide — NADS, Evan Kinori, Asket, and MARO- ship internationally. Check each brand’s website for shipping details and rates to your country.
How do I know if a brand's sustainability claims are real? Look for independently verified certifications such as GOTS, OEKO-TEX Standard 100, Fair Trade Certified, and B Corp. Avoid brands that use unverified language like “eco-friendly,” “natural,” or “sustainable” without third-party certification to back it up. Brands that are transparent about their supply chain, materials, and manufacturing processes are generally more trustworthy.
