You've probably done this: clicked on a sustainable underwear brand, liked what you saw, then closed the tab when you saw the price. A single pair for $18–$30 feels hard to justify when you can grab a 6-pack at Target for $15.
We get it. And we think you deserve a straight answer.
Why Is Sustainable Underwear So Expensive?
Sustainable underwear costs more because certified recycled and organic fabrics cost significantly more per yard than conventional materials, and smaller brands don't get the volume discounts that fast fashion companies rely on. Every step of the supply chain (fabric, dyeing, packaging, shipping) costs more at lower quantities.
When I started sourcing fabric for properbasics, I assumed the price gap would be modest. It wasn't. There are far fewer mills producing certified recycled or organic fabrics than conventional ones. Fewer suppliers means less competition and higher prices. Our GRS-certified recycled nylon costs significantly more than the virgin nylon most seamless brands use. The fabric dyeing adds cost too: we work with an Oeko-tex certified facility in South Korea, which means stricter chemical standards and more careful processes than the cheapest options out there.
None of this is meant to make you feel bad for wanting affordable underwear. It's meant to explain what's actually behind the number on the price tag.
Is Sustainable Underwear Actually Worth It?
When you compare cost per year instead of cost at checkout, sustainable underwear often costs the same or less than fast fashion. Cheap seamless underwear typically needs replacing every six months, while better-made pairs last much longer, making the annual spend comparable.
A typical fast fashion seamless 3-pack runs about $15. Sounds great, until the elastic loses its stretch and the edges start fraying after a few washes. At two replacements a year, that's $30, for underwear made from virgin nylon, produced with no particular regard for environmental impact.
Our 3-pack is $35, and it's built to last longer. We wash-test our fabric and adhesive extensively before production. We're not designing disposable underwear. So the real annual cost is comparable, and in many cases lower.
The difference is what you're getting for that money. With fast fashion, you're paying $30 a year for underwear that fails you, made from new plastic. With properbasics, you're paying a similar amount for underwear made from GRS-certified recycled nylon that gives existing plastic a second life, dyed at an Oeko-tex certified facility. Same budget. Completely different product.
Can Sustainable Underwear Be Affordable?
Yes, if the brand cuts overhead instead of quality. Lower marketing spend, small operations, and direct-to-consumer sales can keep sustainable underwear priced 20% or more below comparable brands without compromising on materials or manufacturing.
That's what we do at properbasics, and it's intentional. We don't spend on big advertising campaigns or influencer partnerships. Lower overhead means we can pass real savings along without cutting corners on fabric or production.
That said, we'll never compete on price with a $2.50-per-pair fast fashion brand. That price point is only possible when someone (a garment worker, the environment, or both) is absorbing the real cost. According to Fast Company, in 1960, American households spent over 10% of income on clothing, compared to just 3.5% today, yet people buy dramatically more garments per year. Our expectations around what clothing "should" cost have been shaped by decades of increasingly cheap production, not by what things actually cost to make responsibly.
Should You Buy Cheap Underwear Instead?
If the lowest possible upfront price is your only priority and you don't mind replacing underwear frequently, cheap options are a valid choice. We'd rather be honest about that than pretend we're for everyone.
But if you've noticed that cheap seamless underwear keeps letting you down (edges rolling, fit loosening, fabric pilling) and you're tired of re-buying the same disappointing pairs, that's exactly the cycle we built properbasics to break.
Sustainable underwear isn't about paying more for the sake of it. It's about paying a similar amount for something that's made better, for you and for the planet.
Next time you're comparing prices, try dividing by how long you think each pair will actually last. That one shift, from "what does it cost?" to "what does it cost per year?", changes the equation entirely.
