When it comes to building a sustainable wardrobe, we often focus on clothing, shoes, and accessories – but what about underwear? It’s easy to overlook, but the truth is, sustainable and eco-friendly underwear is an important part of our everyday lives.
By choosing brands that prioritize ethical production, renewable materials, and waste reduction, you can make a big difference in your environmental footprint.
Here are some of my favorite sustainable underwear brands offering comfort, style, and eco-consciousness.
1. Thinx
Period-Proof and Eco-Friendly
If you’re looking for underwear that combines comfort, sustainability, and functionality, Thinx is a great option. Known for their period-proof underwear, Thinx has revolutionized how we approach sustainable menstruation. They’ve made it their mission to offer eco-friendly alternatives to traditional single-use products like pads and tampons.
Thinx is made with organic cotton and other sustainable materials. They also use water-based dyes and offer products designed to last – cutting down on waste. Beyond that, their business practices focus on transparency and environmental responsibility, making them a top choice for those looking to reduce their environmental footprint while taking care of their bodies.
Price range: $20–$40 USD per pair, depending on style and features.
2. Pact
Organic Cotton Comfort
Pact is a brand that takes sustainability seriously. Their entire collection (underwear included) is made from GOTS-certified organic cotton, which is grown without pesticides or harmful chemicals. Their underwear is soft, breathable, and comfortable, and the brand uses fair-trade factories for production, ensuring that workers are paid fairly.
Pact’s eco-friendly philosophy extends beyond their products, too. They’ve committed to being a carbon-neutral company and use packaging made from recycled materials.
Price range: $12–$25 USD for most items.
3. Organic Basics
Timeless Design with Sustainability Credentials
Organic Basics offers high-quality underwear made from GOTS-certified organic cotton and TENCEL™. They’re serious about transparency, and their factory standards, water usage, and CO₂ impact are all published on their site. Everything feels incredibly well-made, with clean lines and comfy cuts.
Price range: €20–€35 per pair
4. Underprotection
Sexy and Sustainable
Underprotection blends sustainability with fashion-forward designs. Think lacy bralettes and high-waisted briefs made from recycled materials and Lyocell. All their fabrics are certified and they’re a certified B Corp, too.
Price range: €30–€45 per pair
5. Thought
Affordable, everyday organic cotton and bamboo underwear
Specializing in socks and underwear, Thought is a UK-based brand offering cute and comfortable basics made from organic and sustainable materials like bamboo, hemp, and organic cotton. They prioritize ethical sourcing and fair wages while creating high-quality, versatile pieces that stand the test of time.
Price range: $10–$20 per pair
6. Boody
Comfortable, Eco-Friendly, and All About Bamboo
Boody is one of my favorite eco-friendly underwear brands. They’ve mastered the art of comfort with their super-soft bamboo fabric, which is not only gentle on your skin but also a lower-impact alternative to cotton.
Their underwear collection includes everything from briefs and bikinis to boxers and bralettes, and their products are made without harmful chemicals, making them ideal for sensitive skin.
Bamboo is a fast-growing plant that requires minimal water and no pesticides, which makes it an appealing choice for sustainable fashion.
That said, it’s worth noting that Boody uses bamboo viscose, which involves a chemically intensive process. The good news is that Boody is upfront about this and works to reduce its impact by using a closed-loop system and adhering to certified sustainable practices. So while bamboo viscose isn’t a perfect fabric, Boody’s transparency, ethical manufacturing, and fully recyclable, plastic-free packaging make them a solid option.
Price range: $15–$30 USD for most items.
Why Choose Eco-Friendly Underwear?
Sustainable underwear is not just about the materials – it’s about choosing brands that align with your values. By supporting companies that use organic, recycled, or renewable materials, you’re reducing your environmental impact and contributing to a healthier planet.
Moreover, sustainable underwear is often designed to be durable, meaning you’ll need to replace it less frequently, reducing waste over time. Choosing eco-friendly brands like these also supports fair labor practices and reduces the use of harmful chemicals, which is better for your skin.
Making the switch to sustainable underwear might seem like a small change, but it’s one that can have a lasting impact on your wardrobe and the environment. Plus, with so many stylish and comfortable options available, there’s no reason not to make the change today.
