Recently I did a run-down of where to buy ethical women’s underwear.  In it, I promised I would write a guide to men’s ethical underwear too.  So, true to my word, here is a guide to the best ethical options for men’s pants, briefs, and boxers, depending on your preference.  I’ve also updated the article for 2022 – updated in August 2022 – so it is bang up to date.

The Ethical Men’s Underwear Brands to Check Out

As always seems to be the case when it comes to men’s ethical clothing, the market for ethical men’s underwear is considerably smaller than the women’s ethical market.  So you are a little more constrained.  But don’t despair – the market is growing. As such, I’ve tracked down some great men’s ethical underwear companies for you today.

Price Range: £20 – £24

Size: S – XXL

Allbirds*, the ethical shoe retailer, has a small but perfectly formed range of men’s ethical underwear that is made responsibly from sustainable materials.

Its trunks and boxer briefs are made from a blend of sustainable Tencel and mulesing-free merino wool. This makes for a silky-smooth fit that feels barely there. The breathable materials help to wick moisture away, keep you comfortable all day, and help to minimise odour. What’s more, its collection is available in a wide range of colours.

Allbirds say that offering a carefully curated product range fit for all seasons, means that it can maintain a small, tight-knit supply chain.

Need to stock up on undies? Allbirds has a great mix and match deal, where if you buy three pairs of socks or underwear, you get 20% off. 

BAM: Bamboo Clothing

Plymouth-based Bam: Bamboo’s* collection of briefs, boxer shorts and sports trunks are made of exactly what the name suggests: bamboo (as well as being blended with a bit of cotton!).  These have rave reviews from sportsmen and outdoorsy types looking for ethical high-performance technical men’s underwear.

Nudie grey melange organic and fairtrade cotton boxer shorts.

Price Range: £70 for a pack of three

Size: XS – XXL

Nudie’s range of men’s underwear* – from its loose fit boxer shorts to its briefs and trunks – are made entirely from soft, certified organic, and Fairtrade cotton. In plain black, white or grey, these are a great choice if you are looking for basic styles that have been made fairly.

For a clever touch, there’s no annoying care label to itch you. Instead, the care labels are printed on the inside of the underwear. The packaging is also plastic-free – your pants arrive in a recycled cardboard box.

Peau Ethique

Price Range: £7.50

Size: XL – XXL

Peau Ethique is a French-based mother and daughter company, specialising in underwear.  With transparent and ethical operating procedures, your pants and conscience can be clear!  Its men’s ethical underwear is available in the UK through FabOrganics, which has a very limited selection of, ahem, one basic pair of boxer shorts.  The boxers are currently on sale for £7.50 in limited sizes.

WAMA hemp boxer briefs, part of a guide to ethical men's underwear.

Price Range: $28

Size: S – XXXXL

WAMA hemp underwear* is a new one for me in the ethical men’s underwear arena.  WAMA make soft and stretchy men’s boxers, trunks, and briefs from hemp, a crop that generally requires no pesticides and very little water, and renews the soil with each growth cycle.

The downside is that WAMA ships their underwear from America.  Worldwide shipping is a flat fee of $20, regardless of the order value, but bear in mind you may have to pay a customs charge on your order if you are in the UK.

I hope you’ve found this guide to ethical men’s underwear helpful!  Let me know if you find any other makers/stockists in the comments below and I’ll be sure to update the article!
