13 Ethical Underwear Brands For The Eco-Conscious Men

Transitioning into a Zerowasteman is more complex than I initially anticipated. Creating a capsule wardrobe and comprehending the contrasts between fast and slow fashion all contribute to a more sustainable and healthier lifestyle.

Plastic packaging seems to be the most challenging part to eliminate from our life.

But then there are the essentials like new underwear and socks that need to be replaced occasionally.

Given my sensitive skin, I opt for ethical underwear for men. Moreover, I don’t want my purchases to add to the escalating issue of microfiber pollution in our oceans.

Instead of resorting to washing your clothes in a guppyfriend bag, investing in durable, comfortable fair trade boxer briefs seems a superior option. They won’t shed microplastic fibers during the washing process, making this a more eco-friendly choice.

My last pair of underwear was made from bamboo Boody, which I thought was eco-friendly, but it turns out this is a bit more complicated than I thought. They are still on this list since they make ethical underwear for men and women, but as with most companies none of them are perfect as that doesn’t really work in our society.

Sustainable mens underwear final thoughts

Ethical mens underwear is out there and thanks to an ever-growing demand for sustainable clothing this is only the beginning. More and more companies are realizing that the “old” way isn’t acceptable anymore and that they have to take responsibility for their actions.

Workers deserve fair living wages and consumers deserve sustainable underwear mens underwear and clothes in general.

If you are looking to buy more than just eco-friendly mens underwear, have a look at this article that I put together for the zerowasteman in you.

16 Best Affordable and sustainable clothing brands for men


There are many different styles to choose from and many different fabrics. Even if you don’t find something in this list make sure that the fabric you choose is either of these:

  • Tencel (wood pulp)
  • Modal (beech tree pulp, often mixed with other fibers)
  • Hemp
  • Silk (look for cruelty-free silk)
  • Recycled Polyester (I would avoid it, but it is more sustainable than new poly)
  • Bamboo (make sure it is bamboo rayon)

By doing my research I will only list companies that use an ethical supply chain and pay their workers a living wage.
