You probably think it's just a joke or a weird internet myth. It isn't. People are making actual, mortgage-paying money by selling used mens underwear online. Honestly, the first time I heard about the "used" market, I assumed it was some dark-web anomaly that normal people didn't touch. I was wrong. It’s a thriving, surprisingly professional corner of the e-commerce world.
It’s weirdly normal once you get past the initial "ick" factor.
Look, the side hustle economy is basically a free-for-all right now. People sell feet pics, jars of air, and old electronics. But clothing—specifically intimate apparel—has a massive, dedicated buyer base. We’re talking about a demographic that spans athletes, gym rats, and regular guys who just happen to have a specific "vibe" that buyers want. It’s business. Pure and simple.
The Reality of the Market
Who buys this stuff? That’s the first question everyone asks. It isn’t just one type of person. You have collectors. You have people with very specific sensory preferences. You have fans of certain brands like Andrew Christian or Calvin Klein. Some buyers are looking for the "scent" factor, which is a huge part of the valuation, while others just want the aesthetic of a pair of briefs that has clearly seen some miles.
The price points vary wildly. You might see a standard pair of Hanes go for $20, but a well-worn pair of premium gym shorts or jockstraps can easily fetch $100 or more if the seller has a following.
Platforms like PantyDeal, Snifffr, and even specialized corners of Reddit (like r/usedmensunderwear, though you have to watch the rules there) act as the middleman. They provide the infrastructure. They handle the messy bits of traffic so you can focus on the "product." But don't expect to just throw a pair of boxers on a listing and get rich. It takes a certain level of marketing savvy. You're selling a fantasy, a look, or a specific "masculine" energy.
Setting Up Your Shop Without Losing Your Mind
If you’re going to do this, do it right. Don't use your real name. Seriously. Anonymity is your best friend in this industry. Use a pseudonym. Get a dedicated email address that isn't linked to your LinkedIn or your bank account.
Picking the Right Gear
Not all underwear is created equal in the resale world. High-performance fabrics like nylon and spandex blends tend to hold "scent" better, which is a major selling point for a huge chunk of the buyer base. Cotton is okay, but it’s basic. If you want to maximize your margins, you need to look at what's trending.
- Jockstraps: Always a top seller. It’s the classic "masculine" item.
- Briefs: Classic, sporty, and very popular with the "dad" or "jock" aesthetic.
- Wrestling Singlets: These are niche but high-value.
- Gym Shorts: Especially the ones with the built-in liners.
You’ve gotta think about the "wear time." Most buyers want items worn for 24 to 48 hours. Some want them worn during a workout. It sounds intense, but specificity is what drives the price up. If you can prove you wore them during a heavy leg day? That’s a premium.
Why Selling Used Mens Underwear Is Actually a Business
Most people approach this as a hobby, and that’s why they fail. They get bored. They get creeped out. Or they just don't post enough photos. The guys who make four figures a month treat it like a 9-to-5. They have a "content calendar." They know when their "customers" are online.
It’s about the "E-E-A-T" of the fetish world—Experience, Expertise, Authoritativeness, and Trust.
Buyers want to know they aren't being scammed. They want to know the person in the photo is the person who wore the garment. This is why "verification" is so big on sites like AllThingsWorn. You usually have to take a photo with a handwritten note to prove you're real. Once you have that "verified" badge, your sales will likely double. People trust a verified seller. It’s the same reason you check reviews on Amazon before buying a toaster.
Safety and Privacy: The Non-Negotiables
Let's be real for a second. This isn't selling a used bike on Craigslist. There are risks.
Never, ever give out your home address. Use a P.O. Box or a private mailbox service for shipping. When you’re shipping the items, use a return address that isn't your house. Some guys use the address of a local post office or a business center.
Vacuum sealing is your secret weapon. If you’re selling items based on "scent," you can't just toss them in a manila envelope. They’ll lose their "appeal" by the time they cross the country. Use a vacuum sealer. It keeps the scent locked in, and it also makes the package look more professional. Plus, it’s discreet. A flat, plastic-wrapped square looks like a t-shirt or a book, not a pair of dirty socks or underwear.
Payment is the next hurdle. PayPal and Venmo are notorious for banning people who use their platforms for "adult-oriented" sales. It's in their Terms of Service. If they catch you, they'll freeze your funds. You’re better off using crypto or specialized platforms that have their own internal "wallet" systems. Honestly, it’s a headache, but it’s better than losing $500 because a PayPal bot flagged the word "jockstrap" in a transaction note.
The "Scent" Factor and "Wear Time"
This is where it gets technical. Some buyers want "clean" used items—they just like the idea of owning something you wore. But the big money is in the "heavy wear" category.
Typically, sellers offer tiers:
- Standard Wear: 12-24 hours of normal daily activity.
- Workout Wear: Worn during a high-intensity workout.
- Extended Wear: 48+ hours. This usually costs significantly more.
Be honest. If you say you wore them for three days and you only wore them for three hours, the buyer will know. The community is smaller than you think, and word spreads if a seller is "faking" the wear. Authenticity is the only currency that matters here.
Content is King (Even Here)
You need good photos. You don't need a DSLR, but you do need good lighting. Natural light from a window is usually the best. Show the waistband. Show the fit. You don't have to show your face—in fact, many of the top sellers don't. A "faceless" brand can actually be more mysterious and alluring to certain buyers.
Consistency matters. If you post three times a week, you'll stay at the top of the "newest" feeds. If you post once every two months, you're invisible. It's an algorithm game, just like Instagram or TikTok. You’re basically a micro-influencer for a very specific niche.
Misconceptions You Should Ignore
People will tell you it's illegal. It isn't. As long as the items are cleaned (if the platform requires it) or clearly labeled for "novelty use," you’re generally in the clear. However, always check your local laws regarding the shipment of "soiled" clothing. In some jurisdictions, it’s a grey area, but for the most part, as long as you aren't sending anything biohazardous, it’s considered a private transaction between consenting adults.
Another myth? That you have to be a bodybuilder. Nope. There is a market for every body type. "Dad bods," slim guys, "bears," athletic types—there is a buyer for everyone. In fact, some of the most successful sellers are just "average" looking guys who are consistent and friendly in their messages.
Turning Your Side Hustle Into a Business
If you want to take this seriously, start by researching the platforms. Don't sign up for all of them at once. Pick one—maybe PantyDeal (which has a huge men's section) or Snifffr—and build a solid profile.
- Buy a pack of high-quality, name-brand underwear. Think Calvin Klein, Nike, or Under Armour. These have better resale value than generic store brands.
- Take clear, well-lit photos. Use a clean background. No messy bedrooms in the shot.
- Write a descriptive bio. Tell people your vibe. Are you a gym rat? An office guy? A blue-collar worker?
- Set your prices competitively. Look at what other "new" sellers are charging and undercut them slightly until you get your first five reviews.
- Ship fast. Use tracking numbers. Communication is everything.
Selling used mens underwear isn't for everyone. It requires a thick skin and a willingness to engage with a subculture that most people don't understand. But if you can handle the "weirdness," the financial rewards are surprisingly consistent. It’s a low-overhead business with high margins and a customer base that is incredibly loyal once they find a seller they like.
Actionable Next Steps
- Audit your drawer: See if you already own "high-value" brands like Andrew Christian or 2(x)ist.
- Research the platforms: Create a "burner" account on a site like Snifffr just to see how top sellers structure their listings.
- Invest in shipping supplies: Buy a small kitchen vacuum sealer and some discreet, waterproof poly-mailers.
- Establish your boundaries: Decide early on what you will and won't do (e.g., "no face shots," "no custom videos"). Stick to them.
- Launch a test listing: Put one pair up for sale with a 24-hour wear description and see what the response is like.
This market is all about the "long game." Build a reputation for being reliable and "authentic," and the sales will follow. It’s about as "passive" as income gets once you find your rhythm. Just keep your privacy tight and your "product" exactly as described.
