Let’s face it—underwear isn’t something most guys think about… until it rides up, wears out, or smells like it needs to retire. But here’s the thing: that everyday essential sitting closest to your skin has a bigger environmental footprint than you might expect.
Most men’s underwear is made from synthetic materials like polyester or conventionally grown cotton—both resource-intensive and often produced under questionable labor conditions. And when those pairs inevitably stretch thin or tear at the seams, they usually head straight to the landfill.
But what if your boxers or briefs could feel better and do better?
In this guide, we’ll unpack everything you need to know about men’s underwear that’s comfortable, durable, and genuinely sustainable—from the best organic fabrics to ethical brands worth wearing. Whether you're a boxer devotee or a briefs loyalist, this is your guide to making your top drawer more eco-friendly—without sacrificing comfort or style.
Why Choose Sustainable Men’s Underwear?
The average guy might not think twice about what his underwear is made of—but he should. Conventional men’s underwear, especially those made from synthetic fabrics like polyester or non-organic cotton, comes with a heavy environmental cost. From water pollution to unethical labor practices, what’s hidden beneath your jeans might be doing more damage than you realize.
The Hidden Cost of Conventional Underwear
Most mainstream men’s underwear boxers and briefs are made from materials like cotton treated with pesticides or fossil fuel-based synthetics. These fabrics often require:
Toxic chemicals during production, which pollute waterways and harm workers
Excessive water to grow (in the case of non-organic cotton)
High carbon emissions during manufacturing and transport
And once those old pairs wear out? They’re not recyclable or compostable. That means your stretched-out briefs are likely sitting in a landfill—where they’ll stay for decades.
The Sustainable Solution: A Win for You and the Planet
Sustainable men’s underwear flips that script. By choosing underwear made with natural, low-impact materials like organic cotton, hemp, or TENCEL™, you're supporting healthier ecosystems and cleaner production. Organic cotton, for example, uses up to 91% less water than conventional cotton and is grown without toxic pesticides.
But it’s not just about the planet—it’s also about your skin. Breathable, natural fabrics are:
Hypoallergenic and gentler for sensitive skin
More breathable, reducing odor and discomfort
Durable, meaning fewer replacements over time
When you invest in men’s organic cotton underwear or other eco-friendly styles, you’re also supporting brands that prioritize ethical labor practices, transparent sourcing, and often plastic-free packaging.
Long-Term Comfort Meets Long-Term Impact
Sure, comfort and fit matter. But knowing that your underwear was made responsibly, by people paid fairly, from materials that won’t pollute the earth? That’s a confidence boost that lasts all day.
Types of Underwear for Guys (and What to Look for)
When it comes to men’s underwear, comfort is king—but sustainability is becoming a close second. From classic briefs to relaxed boxers, understanding the different types of underwear for guys can help you find a fit that feels great while supporting brands doing better by the planet.
Here’s a breakdown of the most common men’s underwear styles—and what to look for when shopping sustainably.
Boxers
Loose-fitting and breathable, men’s underwear boxers are great for lounging or sleeping. They offer maximum airflow and comfort but may lack support for daily wear or physical activity.
Sustainable tip: Choose boxers made from organic cotton or TENCEL™ for breathable, non-toxic comfort that’s easy on your skin and the planet.
Briefs
Briefs are the go-to choice for guys who want full support without extra fabric. Ideal under slimmer pants or for active wear, cotton briefs for men provide a snug fit that stays put.
Sustainable tip: Look for brands using GOTS-certified organic cotton—it’s grown without harmful pesticides and uses less water than conventional cotton.
Boxer Briefs
Combining the length of boxers with the fit of briefs, boxer briefs are the most popular choice among men. If you’re unsure where to start, this style is a safe (and sustainable) bet.
Sustainable tip: Seek out blends like organic cotton with a touch of elastane for stretch, and make sure the brand is transparent about fabric sourcing and labor practices.
Trunks
Trunks are essentially shorter boxer briefs. They’re modern, minimal, and often favored for their sleek look. Great for men who like support without excess length.
Sustainable tip: Since trunks hug the thighs, moisture-wicking materials like TENCEL™ or hemp blends can improve comfort and breathability.
What to Look for Beyond Fit
No matter the style, sustainable men’s underwear should check more than just the comfort box. As you shop, here’s what to keep an eye out for:
Fabrics: Favor organic cotton, hemp, or TENCEL™ over synthetics.
Certifications: Look for trusted labels like GOTS, OEKO-TEX®, and Fair Trade.
Ethical manufacturing: Choose brands that ensure safe working conditions and fair wages.
Packaging: Bonus points if your new undies come in recyclable or compostable packaging.
So, whether you're a boxers-or-briefs kind of guy—or somewhere in between—there’s a sustainable option out there that fits your style and values.
Best Sustainable Fabrics for Men’s Underwear
When it comes to choosing the best men's underwear, fabric matters more than you might think. The material you wear every day impacts not just your comfort and skin health, but also the environment. Let’s break down the best sustainable fabrics for men’s underwear—the ones that offer breathability, durability, and peace of mind.
Organic Cotton
Organic cotton is a top choice for men’s organic cotton underwear, and for good reason. Unlike conventional cotton, which is grown with heavy pesticide use and high water demand, organic cotton is cultivated without toxic chemicals and typically uses less water. It’s gentle on the skin, breathable, and ideal for those who prefer cotton briefs for men with a softer, more natural feel.
Look for certifications like GOTS (Global Organic Textile Standard) to ensure you’re getting the real deal.
Best for: Everyday comfort, sensitive skin, and eco-conscious shoppers who want a familiar, natural fiber.
Hemp
Don’t overlook hemp—it’s one of the most durable and eco-friendly fibers out there. Hemp requires minimal water, grows quickly without pesticides, and even improves soil health. It also has natural antibacterial properties, making it a solid option for men’s underwear boxers that stay fresher longer.
Hemp blends are typically combined with organic cotton to improve softness while maintaining strength.
Best for: Men who want long-lasting, breathable underwear with less odor retention.
TENCEL™ (Lyocell and Modal)
TENCEL™, a branded form of lyocell and modal, is made from sustainably sourced wood pulp—usually eucalyptus or beech trees—in a closed-loop production system that recycles water and solvents. This silky-soft fabric is moisture-wicking, breathable, and biodegradable, making it a great option for both performance and casual wear.
You’ll often find TENCEL™ in the best men’s boxer briefs because of its smooth texture and stretch.
Best for: Men who want softness, temperature regulation, and sustainable innovation.
Bamboo (with Caution)
Bamboo sounds eco-friendly—and it can be—but not all bamboo underwear is created equal. Traditional bamboo viscose requires chemical-heavy processing, which isn’t environmentally ideal. However, some brands use closed-loop or mechanically processed bamboo, which is a safer, more sustainable option.
If you’re considering bamboo, make sure the brand discloses how the fabric is made and whether it carries OEKO-TEX® or FSC certifications.
Best for: Those looking for ultra-soft fabric, especially for loungewear or hot climates.
Each of these fabrics brings something different to the table, but they all share one goal: reducing your impact without compromising on comfort. As we dive deeper into ethical brands and smart buying tips, keep these materials in mind—they’re the foundation of truly sustainable underwear.
Certifications & Claims to Look For
When shopping for men’s underwear with sustainability in mind, it’s easy to get lost in marketing jargon like “eco-friendly,” “natural,” or “green.” But not all claims are created equal. That’s why third-party certifications are so important—they help cut through the fluff and tell you which brands are actually walking the talk.
Here are the most trustworthy certifications to look for when buying organic cotton men's underwear, mens organic underwear, or any other eco-conscious undergarment.
GOTS (Global Organic Textile Standard)
If you see the GOTS logo on a pair of organic cotton boxers, that’s a good sign. GOTS is the gold standard for organic textiles. It ensures the cotton is grown without toxic pesticides and that every step of the production process—from farming to dyeing—is socially and environmentally responsible.
OEKO-TEX® Standard 100
This label guarantees that the fabric is tested for harmful chemicals and is safe for direct contact with your skin. If you’re choosing cotton briefs for men or organic cotton underwear mens, look for this certification to ensure a non-toxic experience.
Fair Trade Certified™
Fair Trade goes beyond materials. It ensures that the people who made your mens underwear boxers were paid fair wages and worked under safe conditions. Ethical production is a core part of sustainable living—and this label gives you peace of mind.
B Corp Certification
While not specific to underwear, B Corps are businesses committed to high standards of environmental and social performance. If you spot a brand selling the best men's boxer briefs and they’re a certified B Corp, it means they’re serious about transparency and accountability.
FSC-Certified Packaging
Even the packaging matters. Look for brands using FSC-certified paper packaging instead of plastic—it means the material came from responsibly managed forests. A small detail, but a meaningful one in a zero-waste lifestyle.
By choosing men’s underwear from brands with these certifications, you're not just buying a product—you’re investing in a more ethical and sustainable system. It’s a simple way to align your everyday essentials with your values.

What Makes Men’s Underwear ‘Best’?
With so many styles, fabrics, and brands on the market, what makes men’s underwear truly the best—especially for those prioritizing sustainability?
It’s more than just fit or looks. The best men’s underwear strikes a balance between comfort, durability, ethical production, and eco-conscious materials. Here’s what to look for when upgrading your top drawer:
Comfort That Lasts All Day
Let’s start with the obvious. Men’s underwear best serves you when it feels good from morning to night—no bunching, chafing, or riding up. Look for styles like organic cotton boxer briefs or cotton briefs for men that are soft, breathable, and offer just the right amount of stretch without synthetic overload.
Sustainable Fabrics
The foundation of great men’s underwear is what it’s made of. Prioritize:
Organic cotton: Gentle on your skin and grown without toxic pesticides.
Hemp: Naturally antibacterial, breathable, and incredibly durable.
TENCEL™/Modal: Made from sustainably sourced wood pulp, it’s ultra-soft and moisture-wicking.
These materials not only reduce your environmental footprint but also improve wearability over time. If you're looking for the best men's boxer briefs or organic cotton men's underwear, these are the fabrics to trust.
Durability Over Disposability
Fast fashion underwear might be cheap, but it’s rarely built to last. The best men’s underwear holds its shape and softness after dozens of washes, meaning you’ll replace it less often—cutting down on waste and saving money long-term.
Ethical and Transparent Production
Look beyond the tag. The top brands for men’s organic cotton underwear openly share where and how their products are made. Look for certifications like GOTS, Fair Trade, or OEKO-TEX®, which signal a commitment to fair wages, safe working conditions, and reduced chemical use.
Eco-Friendly Packaging and End-of-Life Impact
Even the best underwear ends up retired eventually. Choose brands that use compostable or recyclable packaging and offer take-back programs or tips for responsibly disposing of worn-out pairs. Bonus points for brands designing underwear that’s biodegradable or made from mono-materials that simplify recycling.
How to Wash and Care for Sustainable Underwear
Choosing organic cotton men’s underwear or other eco-friendly boxers is a great first step—but how you care for them matters just as much. Washing and drying techniques can significantly impact the lifespan of men’s underwear, as well as its environmental footprint.
Here’s how to keep your sustainable underwear looking and feeling its best:
Wash in Cold Water
Hot water isn’t just harsh on fabric—it also uses more energy. Washing in cold water is gentler on natural fibers like organic cotton, TENCEL™, and hemp. It helps preserve elasticity and prevents shrinking, especially in cotton briefs for men.
Pro tip: Turn underwear inside out before washing to minimize pilling and wear on the outside.
Use a Gentle, Non-Toxic Detergent
Skip the synthetic fragrances and harsh chemicals. Instead, choose a natural laundry detergent that’s free from sulfates, dyes, and optical brighteners. This protects sensitive skin and ensures your men's organic cotton underwear stays breathable and soft.
If you want to go the extra mile, consider a detergent made specifically for delicates or low-waste living. (Bonus if it's biodegradable and plastic-free.)
Avoid Fabric Softeners
Fabric softeners might promise softness, but they coat natural fibers in a waxy layer that reduces absorbency and breathability—two things you want in your best men’s boxer briefs. Over time, this buildup can even damage elastic bands.
Stick to a vinegar rinse if you want a natural softening alternative.
Air Dry When Possible
Tossing underwear in a hot dryer can break down elastic and fade colors. Line drying or laying flat to dry is the best way to preserve the shape, fit, and integrity of your mens underwear boxers.
It also saves energy, making your laundry routine even more sustainable.
Skip the Bleach
Even on white underwear, chlorine bleach can degrade natural fibers and shorten the lifespan of your clothing. For stains or odors, opt for natural solutions like baking soda or oxygen bleach.
Proper care isn’t just about keeping your underwear clean—it’s about making sure your sustainable investment actually lasts. After all, what’s the point of buying organic cotton if it falls apart in six months?
When you wash with care, you get more wear—and that’s better for both your wallet and the planet.
The Bottom Line: Choose Underwear That Fits Your Values
Sustainable living isn’t just about the big changes—it’s about the small, everyday choices that add up. And what’s more everyday than underwear?
From breathable organic cotton boxers to ethically made cotton briefs for men, there are now more options than ever to align your wardrobe with your values. Choosing the best men’s underwear isn’t just about comfort—it’s about supporting materials that are gentle on the planet, brands that treat workers fairly, and products designed to last.
By making the switch to organic cotton men’s underwear, you’re taking a simple but powerful step toward reducing waste, avoiding toxic chemicals, and building a wardrobe that reflects your commitment to sustainability.
