Buying underwear has never been the most exciting task… but choosing eco-friendly ones is already a big step in the right direction. And since it’s not always easy to navigate the jungle of “green” claims, we decided to put together a clear, straightforward overview of the brands that really matter in the world of eco-friendly men’s underwear.
Of course, opting for trunks that respect the planet won’t save the oceans by themselves, but it’s still a meaningful gesture. So it’s worth making it an informed choice: where do the fibers come from? Who makes them? And above all… do these underwear pieces hold up after three washes? Here, we give you the key facts, the strengths, and—transparently—the small flaws or strong points you should know before heading to checkout.
In short, you make the effort to choose underwear that’s better for the planet; we make the effort to make your choice easier. Deal? Let’s dive in.
Pact
Pact offers a wide range of underwear (trunks, briefs, boxer briefs, t-shirts, socks) made from GOTS-certified organic cotton. The brand emphasizes ethical production in India in Fair Trade USA–certified factories, while offsetting its CO₂ emissions to remain carbon neutral.
Good to know: prices are affordable (around €21 each), but some customers report sizing inconsistencies and variable quality, likely due to the elastane, which can give a plasticky feel.
Cottonique
Cottonique is made for the most sensitive skin: its underwear is 100% hypoallergenic organic cotton, with no latex, no elastane, and no chemicals. Each model is designed to avoid irritation: flat seams, tag-free labels, and waistbands covered with organic cotton.
Minor drawback: comfort is excellent, but the design remains very basic and functional—perfect for those who live by the “less is more” philosophy.
Colorful Standard
Minimalism and bold colors define Colorful Standard trunks, made in Portugal from 95% organic cotton and a touch of elastane. The brand emphasizes durability, no logos, and FSC-certified packaging.
Note: despite its strong messaging, the brand doesn’t disclose the origin of its cotton or production conditions. Also, its garment-dyeing process can cause slight uneven fading over time.
Knowledge Cotton Apparel
Knowledge Cotton Apparel trunks are produced in China, but every step of production is carefully documented. The brand holds strong certifications (GOTS, FSC, Regenerative Organic Certified, PETA Vegan Approved) and offers fair pricing (about €30 for a two-pack).
Weak point: centralizing production in China means long-distance transport and therefore a higher carbon footprint than local manufacturing.
Armed Angels
Armed Angels offers trunks in organic cotton or Tencel, GOTS and PETA Vegan Approved, and made in Turkey. Their approach combines sustainable materials and modern design, at accessible prices (around €19).
Small drawback: the range is limited to trunks, with no briefs or boxer briefs available for those who prefer other cuts.
Dedicated
More sportswear-oriented, Dedicated makes its trunks in India from Fairtrade-certified organic cotton (95% cotton, 5% elastane). The brand stands out with bold, graphic prints that appeal to fans of casual, expressive looks.
Keep in mind: this bold style may seem less subtle or refined than other brands, making it best suited for those who enjoy expressive underwear.
WAMA Underwear
WAMA innovates with underwear made from organic hemp (53%) blended with organic cotton and a little elastane. Produced in BSCI-certified factories in China and WRAP-certified factories in Vietnam, they are also PETA Vegan and Oeko-Tex Standard 100.
Good to know: the fabric is thicker, retains some moisture, and the items run small—better to size up.
Boody
Boody makes briefs, trunks, and socks from bamboo-derived viscose (95%), with its factories B-Corp certified. The seamless models are soft and comfortable, and prices remain accessible (€15–22).
Note: bamboo requires heavy chemical processing to turn into viscose, which complicates the eco-friendly claim.
NADS
The young Turkish brand NADS designs boxer briefs and trunks in GOTS-certified organic cotton, with a 100% organic cotton lining and Oeko-Tex certified non-toxic dyes.
Drawback: the selection is quite limited, and products may shrink slightly (up to 5%), so sizing up is recommended.
Bluebuck
Finally, Bluebuck stands as a reliable reference in eco-friendly men’s underwear. The brand uses only organic cotton (GOTS-certified) and recycled fibers, including marine plastic waste transformed into yarn via the SEAQUAL initiative. Production is 100% European: mainly in Portugal (factories powered by renewable energy), but also in Austria (elastic waistbands) and Italy (100% cotton jacquard labels).
Bluebuck also stands out for its transparency and durability: timeless collections never on sale, designed to last, and a strong commitment by donating 1% of annual revenue to environmental organizations.
In short: a trustworthy, committed, and demanding brand that proves eco-responsibility can rhyme with quality and style.
Finding eco-friendly men’s underwear that combines style, comfort, and a positive impact is no longer a struggle. Each brand listed here has its strengths, commitments… and sometimes small flaws, because nobody’s perfect.
The most important thing is to choose consciously: know where what you wear comes from, how it’s made, and who you’re supporting with your money. And if this guide has helped you see things more clearly, then mission accomplished.
