The Best Underwear for Men (2025)

By now, you know the importance of pulling together a wardrobe full of foundation pieces to keep you ready for any and all occasions. So why do so few guys extend this investment-minded strategy to their…well, foundation? 

Women have understood this “look good, feel good” factor — even when no one can see it! — for a long time. Hello, they don’t sell matching bra and underwear sets for nothing!

Meaning? Now is the perfect time for you guys to catch up and care about what you’re wearing underneath it all.

Below, 5 things you may not know about finding the best underwear for men:

1. Base layers affect your entire outfit

Ready to take a page out of women’s style playbooks? Great, start here: give more thought to your underwear when planning an outfit.

“If you have the right fitting underwear, everything else fits better. Women won’t wear a baggy bra or saggy underwear (unless it’s laundry day). Similarly, men look and feel much better when they take a 21st century approach to their base layers,”  says Tom Patterson, the co-founder of Tommy John.

We couldn’t agree more.

As the trend in pants remain on the slim or straight-leg tip, take both comfort and appearance into account when choosing your underwear.

Combatting visible lines with our underwear has been a long, hard-fought battle for women. We even have a name for this dreaded look: VPL, or “visible panty line.” 

This is relatively new territory for you fellas, though. Luckily, plenty of brands have made improvements to both material and cut that will change how you feel and look in every layer of your clothes.

But this isn’t just a ploy on the part of marketers to get you to buy more expensive undergarments. 

Switching from the “Save” to the “(mildly) Splurge” category can be worth the increase in your wardrobe budget. According to Patterson, “Underwear is often the last upgrade in a guys closet or life,” which is crazy, considering underwear fits, fabrics, and functionality have changed more in the last two years than the last 25.

2. Not all underwear is created equal

“Guys are realizing that comfortable, high-quality underwear options do exist.” notes SilkCut Underwear president Adam Dinkes.

That’s right, guys; a 5-pack of boxers need not be your only source of underthangs. Look to big brands innovating their lines as well as online-only options that got their start on “I made it ‘cuz I needed it” platforms like Kickstarter.

What kinds of improvements, you ask?

Think: more comfortable stitch placement and waist band width. To find the style that’s right for you, Dinkes suggests, “Buy two or three different pairs to see how they feel, how they fit, and what you find most comfortable.”

Most importantly? Don’t assume the style (or even size) you’ve always worn is the most comfortable.  Try some new fabrics and some new shapes.  Odds are there’s a whole new world of comfort out there.

3. Fabric matters

Let’s do a quick rundown, shall we?

Moisture-wicking: Pulling moisture away from your body and drying considerably faster than traditional cotton is an ideal undergarment quality regardless of season, so keep an eye out for this to be a component of most new lines.

Antimicrobial: Your first line of defense against imminent sweat? The bacteria (and odor) resistant antimicrobial property of certain fabrics in a lot of garments today. Look for this on the label next time your shopping for active or everyday underwear.

Micromodal: The finest of undergarment fabrics that results in a seriously soft feel with an almost airy weight. It’ll dry quick and offer an endless stretch – making it perfect under your skinny jeans or three-piece suit.

Classic cotton: Already known for its cool, dry comfort, updated cotton fabrics now dry considerably faster for a soft feel that will remain durable.

Polyester/spandex blend: Compression shorts are known for this combination that tends to feel tighter than most fabrics, while feeling flexible enough for any workout you put them through.

…and these are just a sample of the vast fabric choices you have at your disposal. Since what you wear and where you go constantly changes, keep your underwear rotation up to par for maximum functionality.

4. Different underwear works best for different occasions

We can all agree that you wouldn’t pull on sweatpants for date night at a five-star restaurant, so why do so many guys treat their underwear as “one occasion fits all?”

If it sounds ludicrous to wear baggy boxers from your college days under a slim-fitting suit…that’s because it is.

“Loose boxer shorts are really becoming a dinosaur on the market since pants are more fitted and men want a more streamlined based layer.” says Patterson. 

There is an ever-expanding array of options available to you guys based on fit and fabric for any occasion or preference. As advocates of occasion-based undergarments, we promise there’s enough room in your dresser drawers for micromodal briefs to wear with your suit, cotton boxers to sleep in, and spandex compression shorts for your next workout.

5. Women notice your underwear!

Think about your underwear the way you think about ours! If we’re getting hot and heavy, only to reveal a sweaty sports bra and granny panties underneath our clothes, well, that’s not so attractive, right?

Another thing women don’t want to see? Adjusting your junk in public.

By better understanding how guys move, newer brands have found ways to fix your foundation’s fit. That means less rolling, bunching, and (thankfully) less adjusting.

SG Says: Thanks to its weirdly innovative quick draw fly—a horizontal opening that allows the wearer “easy access when you need it most.”

SG Says: You can find Pair of Thieves at Target, or on Amazon, which is nice, as you don’t necessarily want to drop too much money on a totally refreshed underwear drawer without trying one pair first to make sure you like them.

They’re a little bigger in the leg, so if you’re walking around on skinnier stems, this style may not be for you.

SG Says: Made of a soft Tence Lyocell material, CDLP’s boxer briefs even feel like the creme de la creme of men’s underwear. Think: almost silky. Meaning they’re uber-comfortable to wear all day.

Best of all? They somehow keep you snug while also feeling almost like…they’re not there at all? Men’s underwear magic!
