A Brief Review of 9 Ethical Mens Underwear Brands

The SJ Team


Climate change and fast fashion aren’t the only sensitive areas we’ll be covering in this article: it’s time to unpack(age) the world of ethical mens underwear.

To put it briefly, traditional synthetic underwear—often manufactured using formaldehydes—are pretty junky for your junk, having been linked with low sperm count, and cancer.

And while secondhand skivvies are undoubtedly the most sustainable option, are you game enough to sport someone’s pre-loved jock-strap?

Us neither.

So how do we navigate this delicate issue for our delicate bits?

About Mighty Good Basics:

Mighty Good Basics and sustainable practices are mighty good mates. 

Producing ethical underwear made in Australia, this company is an expert in supporting your “‘down under”’ region (and the environment) with their trunks, boxer-briefs, and briefs. 

Mighty Good Basics’s Ethical and Sustainability Practices

Materials: 

Fair Trade and a GOTS certification is no easy feat, but MGB maintains strict standards around the organic cotton that makes up 95% of each skivvy used in their garments. 

The other 5% is elastane, and they only use AZO-free dyes.

GOTS certification guarantees a positive impact on the environment, workers, and long lasting products for customers.

Supply Chain & Labor Practices: 

The health and wellbeing of MGB’s employees is a top priority for this sustainable men’s underwear brand. 

Their website provides detailed, transparent information on all of their suppliers and dives deeply into the specifics of what is available to their employees. 

For instance, their cotton mill in Rajlaskhim provides life-changing access to education, free transportation, and discounted meals, above minimum wage, with 12% rental supplementation, and medical insurance for them and their families. 

Green Business Practices: 

While MGB is still working on a recycling program for their ethical underwear, they are still ahead of the hip curve with green eco-conscious innovations during the manufacturing process.

They use reverse osmosis purification plants that allow them to recycle and reuse water. Another wonderfully implemented technique is the burning of rice husks (normally waste) for steam creation instead of fossil fuels.

Lastly, they have a campaign called Bare For Good that does interviews with Australian change-makers to spark the conversation on how we relate to our clothes and where they come from.

Inclusivity: 

Sizing for ethical men’s underwear are XS- XXL.

Community & charitable giving:

Their Bare For Good campaign interviews Australian change-makers to spark conversation on the importance of how we relate to our clothes and where they come from.

How We Found The Best Ethical Mens Underwear

Interested in getting under(wear) the surface of what it truly means to be a sustainable brand? 

Visit our article on sustainable and ethical fashion to understand, in depth, the criteria we look for.

Materials: 

When seeking sustainable fabrics for environmentally friendly mens underwear, we ask ourselves a few things.

Is it renewable? Made with natural materials? Grown without chemical inputs? Have low-impact on the environment? If yes, then it’s for us. 

That means we saw a lot of organic cotton, along with semi-synthetics like TENCEL lyocell fabric, modal fabric, and bamboo fabric.

Virgin elastane or spandex is still somewhat unavoidable if we want some stretch to our skivvies, but ensuring it’s less than 10% means the garment can still be composted.

Supply Chain & Labor Practices:

No ifs, and, or but(t)s, brands demanding transparency on the treatment and working conditions of their employees are changing the game to avoid the likes of another Rana Plaza collapse. 

Industry wide standards are put in place for safety and health, and companies can seek certifications that speak to their transparency and production practices, from farm to customer. 

Green Business Practices: 

Brands who actively care and set out to reduce their carbon footprint are stepping up and taking responsibility for their company’s impact on the environment. 

Going with energy and water conscious manufacturing, supporting carbon offset programs, making packaging recyclable and compostable, and having garment take-back programs are just a few ways brands can kick climate change’s butt!

Inclusivity:

Body-positive brands showing off their diverse models sporting bootyful bottoms’ turn our heads.

Community & Charitable Giving:

Nothing feels better than knowing your hard-earned dollars are going to a worthy cause (and maybe a pair of ASKET’s Egyptian cotton underwear, at the same time). 

From monetary or physical donations to life-changing internship programs, we should all be inspired to do more, one purchase at a time.


Final Thoughts On Sustainable Mens Underwear

We want to make sure our butts are covered when making decisions that impact the health of our skin and our planet. 

Granted, underwear is often an afterthought, but since no-one really ‘sees it’, how harmful can it be, really? 

But like climate change, just because you can’t see it, doesn’t mean it isn’t important. 

Support the world by supporting yourself with better quality, longer lasting ethical mens underwear, and spread the word on your journey to a sustainable wardrobe.
