Developing a more sustainable style starts with the basics. While men’s underwear often stays out of sight, it’s one of the most worn and impactful items in your wardrobe. From the materials touching your skin every day to the way they’re produced, your underwear choices matter more than you might think.
At COSH, we believe more conscious shopping should extend to every layer, which is why we’re spotlighting more sustainable men’s underwear that combines comfort, durability and more responsible production. Whether you’re looking for breathable organic fabrics, fairer working conditions or long-lasting essentials that reduce waste, this guide helps you upgrade your underwear drawer without compromising your values.
Pioneering brands
Merz b. Schwanen, Dedicated, Colorful Standard and A‑dam aren’t just brands; they’re torchbearers of sustainability in men’s underwear. These brands redefine the concept of more responsible fashion with a focus on organic and recycled materials, more ethical labour practices and fairer wages. Their transparent and efficient production methods significantly reduce environmental footprints, setting a new standard in the fashion industry.
What makes underwear more sustainable?
Contrary to popular belief, more sustainable underwear doesn’t mean wearing the same pair for days! Instead, it’s about choosing underwear crafted from high-quality (vegan) materials like organic cotton and bamboo.
These natural materials are not only gentle on the environment but also kind to your skin whilst offering unparalleled comfort. Forget synthetics! After all, your underwear is the first thing you put on, and the last thing you take off, and fossil fuel fibres won’t provide the breathability your skin needs.
Comfort and quality
Comfort and quality are essential when choosing more sustainable men’s underwear, because the more comfortable and well-made a piece is, the longer you’ll wear it. High-quality and natural fabrics feel softer on the skin, breathe better and retain their shape after repeated washes, reducing the need for frequent replacements. When underwear lasts longer and feels good all day, it naturally supports a more sustainable wardrobe. It creates less waste, fewer resources need to be used and a better experience for both you and the planet.
Timeless style
No need for dull tighty-whities! The collections from these brands offer a variety of styles, colours and designs, proving that more eco-conscious underwear can be trendy and diverse. With options like A‑dam’s stylish prints or Merz b Schwanen’s timeless appeal, you’re all set to impress, even in the most intimate of settings.
Caring for the planet can start with your boxers

Albero Natur
Coloured underwear in organic cotton and different fits
The German brand Albero Natur understands that not all men want to wear the same fit of underwear. Some men like tight boxers, some like longer boxers, more loose ones and some prefer to wear briefs. So they decided to make all kinds of different fits in different colours. But there are 3 things they have in common: they are comfortable, made of organic cotton and produced more fairly at their trusted manufacturer in Turkey.

And on top of that, they also pay attention to a more sustainable way of production, because they are made in a local sewing factory near Düsseldorf.
