It happens to almost every guy at least once. Maybe you’re running late, the laundry hasn’t been switched to the dryer, and you realize you’re down to your last clean pair—which is currently a damp ball of cotton. So, you shrug, pull on your jeans, and head out the door. That first hour feels weird. A little risky, maybe. But then, something changes. You notice the airflow. You realize the nagging pinch in your groin is gone. Suddenly, the idea of men with no underwear doesn't seem like a punchline from a 90s sitcom anymore; it feels like a genuine lifestyle upgrade.
Honestly, "going commando" is one of those topics men rarely discuss in detail, yet it’s a practice rooted in history, biology, and, increasingly, modern health trends. It isn't just about being lazy with the laundry. For some, it’s a calculated choice to improve skin health or fertility. For others, it’s just about comfort.
The Science of Going Without
Let’s talk about the biological side of things because that's where the real benefits often hide. Human anatomy—specifically the male reproductive system—wasn't exactly designed to be wrapped in three layers of tight synthetic fabric for 16 hours a day. There is a reason the testes are located outside the main body cavity. They need to stay cool.
Research published in journals like Human Reproduction has long suggested that tight-fitting underwear can lead to increased scrotal temperatures. When things get too hot down there, sperm production takes a hit. It’s a delicate balance. While the study didn't explicitly say "everyone must stop wearing boxers," it did highlight that men who wore looser styles (or nothing at all) had significantly higher sperm concentrations than those who favored tight briefs.
Beyond the fertility aspect, there’s the skin to consider. We’ve all dealt with it: the dreaded "jock itch" or general chafing. This is usually caused by Tinea cruris, a fungal infection that thrives in warm, moist environments. By ditching the extra layer, you’re basically pulling the plug on the fungus's favorite habitat. Air circulation is the enemy of bacteria and fungi. It’s simple physics, really.

Historical Context and the "Free" Movement
Men with no underwear isn't a new phenomenon. In fact, for the vast majority of human history, underwear as we know it didn't exist. Ancient Romans had the subligaculum, but it wasn't a universal staple. High-fashion underwear is a relatively modern invention, spurred by the industrial revolution and the rise of mass-produced textiles.
In the 1920s and 30s, the invention of "briefs" changed the game, marketed as a way to provide support. But before that? Men just wore their trousers. Even today, in many cultures across the globe—from the Scottish Highlands and the traditional kilt to various indigenous groups—the "no-layer" approach is the standard. It’s only our modern Western obsession with "support" and "hygiene layers" that makes the concept feel radical.
The Real-World Practicalities (And the Risks)
Look, I’m not going to sit here and tell you it’s all sunshine and rainbows. There are logistics to consider. If you’re wearing heavy, raw denim jeans without a barrier, you’re playing a dangerous game with your zipper. Chafing against rough seams is a very real thing.
Most guys who commit to this lifestyle change their wardrobe accordingly. You start looking for pants with softer linings. You might lean more toward chinos or joggers. You also have to be more diligent about hygiene. Your trousers are now the frontline. That means you can’t wear the same pair of jeans for three weeks straight without a wash. Your skin oils and sweat are going directly into the fabric of your pants.

When to Keep the Gear On
There are times when going without is a terrible idea.
- The Gym: High-intensity movement without support can lead to discomfort or even injury (like a strained inguinal canal). Plus, communal gym benches? No thanks.
- Formal Events: If you’re wearing rented formalwear or thin dress slacks, the lack of a silhouette-smoothing layer can lead to some... visible issues.
- Cold Weather: Underwear provides a crucial thermal layer. In sub-zero temperatures, you want every bit of insulation you can get.
Breaking Down the Comfort Myth
Many men assume they need "support" to go about their day. But if you look at the mechanics of the human body, your muscles and connective tissues are generally up to the task of holding everything in place for low-impact activities like walking or sitting at a desk. The feeling of "heaviness" some report when they first try going commando is often just a lack of familiarity with the sensation of movement.
Psychological Freedom
There is a weird psychological component to this. Men with no underwear often report a sense of "freedom." It sounds cheesy, but removing a restrictive band from your waist can subtly change how you feel throughout the day. It’s one less thing pressing into your skin. It’s one less seam to adjust.
I spoke with a long-distance hiker once who swore by it. He claimed that after the first 50 miles, any extra fabric was just a liability for blisters and heat rash. He’s not alone. There’s a whole community of "ultralight" enthusiasts and outdoor professionals who view underwear as an unnecessary weight and a source of friction.

Making the Transition: A Practical Approach
If you’re curious about making the switch, don’t just throw all your boxers in the trash today. That’s a recipe for a very uncomfortable afternoon. Start small.
First, try it at night. Sleeping without clothes is a great way to let your skin breathe without any risk of public embarrassment or "zipper incidents." It helps regulate your body temperature, which can actually lead to deeper, more restorative sleep.
Next, try it on a "low stakes" day. A Sunday at home in sweatpants is the perfect testing ground. You'll get used to the sensation of movement without the constriction of elastic. If that feels good, move up to soft cotton trousers or loose-fitting shorts.
Wardrobe Adjustments You'll Need
- Fabric Choice: Look for natural fibers like linen or soft cotton. Avoid scratchy synthetics or heavy wools directly against the skin.
- Zipper Awareness: This cannot be stressed enough. Be careful. Or, better yet, switch to button-fly pants.
- Laundry Schedule: You will be washing your pants more often. Accept this. It’s the trade-off for the increased airflow.
The Bottom Line on Men With No Underwear
Ultimately, the choice to wear or not wear underwear is deeply personal. There is no one-size-fits-all answer (pun intended). While the health benefits regarding fertility and skin health are backed by solid logic and some significant studies, the primary driver for most men is simply comfort.
If you struggle with constant irritation, if you feel overheated, or if you just hate the feeling of being bunched up, it’s worth experimenting. Just be smart about your pant choice and keep an eye on your hygiene.
Actionable Steps for the Transition
- Audit your pants: Check for rough internal seams or exposed zippers that might cause irritation.
- Night trial: Spend one week sleeping without underwear to gauge your comfort level with the sensation.
- Moisture management: If you decide to go without during a workout, ensure you have moisture-wicking outer gear to prevent sweat build-up.
- Hygiene check: Increase your trouser washing frequency to at least every two wears to maintain skin health.
There is no rulebook here. Whether you choose to go commando every day or just keep it as a "laundry day" backup, understanding the pros and cons helps you make a choice that actually works for your body.
