You probably don't think about your drawers much until they start riding up during a meeting. It's a weirdly personal topic. We spend nearly 24 hours a day with this fabric pressed against our skin, yet most of us are basically wearing the wrong thing or buying based on a brand name we saw on a billboard in 2005. Honestly, the evolution of men in underwear is less about fashion and more about a desperate struggle for comfort and, eventually, a massive shift in how society looks at the male body.
It wasn't always about $30 modal blends.
For a long time, the options were "nothing" or "a giant linen sack." If you look at the history of the loincloth—which is basically where this all started—it was purely utilitarian. Think Ancient Egypt. King Tut was buried with dozens of them. They were basically triangles of linen tied around the waist. No support. No "pouch." Just a barrier between you and your rough outer tunic.
The Massive Shift in How We See Men in Underwear
The 1930s changed everything. Before then, men wore "union suits." You know the ones—the full-body long johns with the flap in the back. They were itchy, bulky, and terrible if you lived anywhere warm. Then came Arthur Kneibler. He was a "hosiery pioneer" at Coopers, Inc., and in 1934, he got a postcard from a friend in the French Riviera showing a man in a sleek, tight-fitting swimsuit.
Kneibler had an epiphany. Why not make underwear that looked like that?

He called them "jockey shorts" because they offered support similar to a jockstrap. When they debuted at the Marshall Field's department store in Chicago during a blizzard in 1935, the store expected a flop. Instead, they sold out of 600 pairs in a single afternoon. People were obsessed. It was the first time men in underwear actually looked... modern. It’s wild to think that a blizzard in Chicago is why you’re probably wearing briefs right now.
Why the "Boxer vs. Brief" Debate is Actually Scientific
Most guys pick a side and stay there for life. But there’s actual health data behind the choice.
A Harvard T.H. Chan School of Public Health study published in 2018 looked at 656 men and found that those who wore boxers had a 25% higher sperm concentration than those who wore tight-fitting briefs. Why? Temperature. The "boys" need to stay about 2 to 3 degrees Celsius cooler than the rest of your body. If you're constantly constricted, things heat up, and biology takes a hit.
But it's not a total win for boxers. Briefs and "trunk" styles provide structural support that prevents "jostling," which is a legitimate medical concern for athletes or guys who are on their feet all day. If you're running a marathon in loose cotton boxers, you're asking for a world of chafing. Chafing is the worst. We’ve all been there, walking like a penguin because we chose the wrong fabric for a long hike.

The Modal Revolution and the Death of "Multipack" Cotton
Stop buying those 5-packs of heavy-duty cotton from the grocery store. Seriously.
Cotton is a "thirsty" fiber. It absorbs moisture but doesn't let it go. This is why if you sweat even a little bit, you're sitting in damp fabric for the rest of the day. Modern brands have pivoted to MicroModal, Tencel, and Bamboo. These are semi-synthetic fibers made from beech tree pulp. They are incredibly soft. Like, "forget you're wearing anything" soft.
- MicroModal: Wicks moisture 50% faster than cotton.
- Merino Wool: Don't laugh. It’s not just for sweaters. Ultra-fine merino is antimicrobial, meaning it doesn't smell even after a long day.
- Spandex Blends: Necessary for "recovery." Without 5-10% Lycra or Spandex, your underwear will bag out by noon and look like a diaper.
The rise of the "pouch" design is another game-changer. Brands like Saxx or MeUndies started engineering internal barriers to prevent skin-on-skin contact. It sounds like a marketing gimmick until you actually try it. Reducing friction is basically the holy grail of men's comfort.
What Celebs Taught Us About Marketing the Male Form
In the 80s and 90s, the image of men in underwear shifted from "functional garment" to "sexualized object." We can thank Herb Ritts and Calvin Klein for that. The 1982 campaign featuring Olympic pole vaulter Tom Hintnaus changed the visual landscape. Suddenly, underwear wasn't something you hid; it was something you showed off over the waistband of your jeans.

Mark Wahlberg’s 1992 campaign took it to another level. It wasn't just about the fabric; it was about the persona. This era birthed the "logo waistband." It became a status symbol. You weren't just wearing briefs; you were wearing a brand. This shift turned a boring commodity into a multi-billion dollar industry. It’s also why we’re now bombarded with Instagram ads for "disruptive" underwear brands every three seconds.
Dealing with the "Ride Up" Problem
We need to talk about leg length.
Briefs have no leg. Boxers have a long, loose leg that bunches up. The "Boxer Brief" was supposed to be the middle ground, but if the "inseam" is too short (usually 3 inches), the fabric will naturally migrate toward your groin as you walk. It’s physics. If you have larger thighs, you need at least a 6-inch or 9-inch inseam. The longer the fabric, the more surface area it has to grip your leg, which prevents it from rolling up into a fabric "donut" around your hip.
Actionable Steps for Better Daily Comfort
Most guys keep their underwear way too long. If the waistband is puckering or the fabric is see-through, it's garbage.
- Check your tags. If it's 100% cotton, keep it for sleeping. If you're going to work or the gym, look for a blend with at least 10% elastic fibers.
- Measure your actual waist. Don't just buy "Large" because you've always been a Large. Different brands have wild variations in sizing. A 34-inch waist might be a Medium in one brand and an XL in a European cut.
- Match the activity to the fabric. Use synthetic "compression" styles for the gym to manage sweat. Use Modal for the office for comfort. Use loose boxers for sleeping to keep things cool.
- Stop using fabric softener. This is a pro tip. Fabric softener coats the fibers in a waxy film, which kills the moisture-wicking properties of high-tech underwear. It makes them feel soft but makes them perform like a plastic bag.
- The "Two-Finger Rule." If you can't comfortably fit two fingers under the waistband, they’re too tight. This constricts blood flow and leads to those red marks that itch all night.
The reality of men in underwear is that we’ve moved past the era of "whatever is on sale." Treat it like an investment in your daily sanity. If you're comfortable at the base layer, everything else in your day just feels a little bit easier to handle.
