Sure, buying a brand new pair of organic cotton boxer briefs may not be as fun as shopping for some hip new sustainable men’s clothing for work or leisure-related activities. However, these under-the-radar hip hugging staples are with you 24/7. So it only makes sense to treat them as a true investment (my husband adores getting new briefs!). For your shopping ease, we made a list of the best sustainable men’s underwear brands to help you add the right pair of eco-friendly boxers to your top drawer!

Some options are neutral enough to match your minimalistic aesthetic, while others offer ample doses of color in case you want your organic men’s underwear to have some personality. To top it all off, some eco-friendly boxers also carry inherently cool prints from top favorite movies.

What is the most sustainable men’s underwear? ​

While there are many ethical men’s underwear options at your disposal, some sustainable brands are dominating the game. Wama, Organic Basics, TomboyX, Maggie Organics, Patagonia, and Pact are only some of the most sustainable men’s underwear brands to keep on your radar with a wide range of soft, bamboo, and organic cotton boxers.

Which fabric is best for sustainable men's underwear?

Organic cotton and natural bamboo is not only the most comfortable material for men’s underwear but also the most eco-friendly and sustainable. Organic men’s underwear made from Bamboo is naturally antibacterial, hypoallergenic, and odor-resistant. These renewable fibers are also extremely strong and durable. Plus, it self-regenerates from its own roots without the use of toxic chemicals.

As for organic cotton boxers, they contain no pesticides or other harmful chemicals which makes them skin-friendly and hypoallergenic. Additionally, it’s one of the most absorbent materials that doesn’t require much water, uses less energy, releases fewer greenhouse gases, and actually improves the quality of the soil.
