16 of the Best Ethical & Sustainable Underwear Brands For Every Body

Kira Simpson

If your underwear drawer needs a sustainable upgrade, but you have no idea where to start, you’ve come to the right place.

Our mantra is always ‘the most sustainable item is the one you already own’ but holey, saggy undies aren’t the best look, so it’s good to give your underwear a refresh every now and then. 

Over the past few years, the amount of standout ethical and sustainable underwear brands has grown tenfold is Australia – so you’re spoilt choice for brands that share your values. Comfortable, breathable undies, the perfect t-shirt bra, or something lacy and a little special – underwear is a very personal purchase, and an investment, so it’s important to get it right.

FAQs on Sustainable and Ethical Underwear

What materials are used in sustainable underwear?

When on the hunt for sustainable undies, here’s what you should keep an eye on:

Materials used: Sustainable underwear is made from materials that are responsibly sourced and often have a lower environmental footprint, meaning they’re produced in ways that minimise water usage, reduce carbon emissions, and avoid harmful chemicals. These include:

  • Organic Cotton: Grown without pesticides and synthetic fertilisers, organic cotton farming emphasises the health of soils, ecosystems, and people.
  • Bamboo: Known for its fast growth and minimal water needs, bamboo fabric is soft, breathable, and biodegradable.
  • Tencel (Lyocell): Produced from sustainably sourced wood pulp, Tencel is lauded for its durability and circular production process.
  • Hemp: A strong, durable fibre, grown with minimal water, that softens with each wash.
  • Recycled Polyester: Often made from recycled plastic bottles and plastic waste, recycled polyester reduces waste and energy consumption compared to virgin polyester.
  • Modal: Modal is a bio-based fabric made from beech tree pulp, celebrated for its softness and lower environmental impact.
  • Organic Linen: Made from the flax plant, organic linen is valued for its natural, biodegradable properties and minimal water usage in production.
  • Ethical Wool: Sourced from farms practising sustainable grazing and animal welfare.

Certified Organic Textiles: Look for fabrics that have received the nod of approval from reputable organisations like the Global Organic Textile Standard (GOTS). Brands committed to sustainability will proudly display their textile certifications alongside their products.

Zero Waste/Low-waste Approach: Unlike fast fashion, which leaves behind a trail of textile waste – remnants discarded on the cutting room floor, destined for landfills – sustainable underwear brands adopt a more conscious stance. They might make to order, repurpose this leftover material or use deadstock (unsold inventory), ensuring that every piece of fabric is valued and utilised.

Eco-friendly Dyes and No Harsh Chemicals: Look for OEKO-TEX certified products, which ensures that every component of a textile product (including every thread, button, and other accessories, as well as the dyes used) has been tested for harmful substances. 

How do I find affordable ethical underwear?

Ethically and sustainably made underwear can be a little higher priced because every person along the supply chain – from seed to garment – is paid a living wage. Finding affordable, ethical underwear can be a challenge, but it’s certainly possible with some research and smart shopping strategies. Shopping during sales or using discount codes can make ethical options more affordable. Additionally, consider investing in high-quality pieces that may have a higher upfront cost but will last longer, providing better value in the long run. Finally, some ethical brands offer basics or multi-pack options, which can be more cost-effective than purchasing individual pieces.

Are there ethical and sustainable underwear options for men?

Absolutely! Sustainable fashion is for everyone, and there are many ethical and sustainable underwear options available for men. You have Boody, Meundies, Thunderpants, and PACT, just to name a few. These brands offer a range of styles, from boxers and briefs to trunks and long johns, all made from sustainable materials like organic cotton, bamboo, or recycled fabrics. 

What are some sustainable underwear brands?

There are lots of great sustainable underwear brands that are committed to ethical and eco-friendly practices. Some of favourites include:

  • Pact: Cosy organic cotton undies, created with fair trade certified factories, are all about comfort with a conscience, proving that sustainability can be soft and stylish.
  • Boody: Uses bamboo to create ultra-soft, breathable, and antimicrobial underwear that’s as gentle on your skin as it is on the environment.
  • Organic Basics: Offers durable and minimalist designs made from organic cotton and recycled materials.
  • MeUndies: Inclusive brand that provides a variety of styles for every body. Made from sustainable, breathable fabrics like Tencel and offers a membership for discounts.
