Eco-friendly men’s underwear: what to look for and where to buy

Boxers, briefs, Y-fronts, long johns – the choice is endless. But how can you make sure your choice of underwear is as good for the planet as it is for you? And how do you avoid that pesky greenwashing? We’re here to help! Read on for what to look out for, and for our roundup of the best brands on the market.

What does an eco-friendly pair of pants look like?

Ideally, your underwear will be made of natural materials and will biodegrade when they reach the end of their lifecycle. But you need to consider other factors too – like the amount of water used to make the fabric and any pollution produced during the process.

If you really want to boost your eco-credentials, look out for bamboo, hemp or lyocell/modal (which are made from wood pulp). It’s also important to think about the carbon footprint of your underwear (how far it has travelled throughout the supply chain), and whether the people who made it are paid a fair wage.

We’ve done the hard work for you and gathered our favourite options below – read on!
