Ready to get some new underwear of best fabric? Look at you, breaking the cycle of men clinging on to their underwear like a bad tinder match.

Seriously. Some of us need a reality check on how long to keep a pair of underwear. More specifically, how long is too long (yes, longer isn’t always better!). But before this turns into a rant, let’s just say you’ve made the right choice.

Though as with many things in life, the right choice isn’t always the easiest. Just when you think you’ve found the perfect underwear style, turns out there’s a huge variety of fabrics out there. And you’ll likely have to pick one.

There’s a reason why that’s a tough choice. Choosing the right underwear fabric can be the difference between a comfy pair of undies and a clammy pair of butt crawlers. Talk about high stakes!

That probably explains why men are so clingy when it comes to their underwear. But you’ve got nothing to fear!

With this simple guide to the best men's underwear fabric types out there, we’ll show you exactly what you need and why you need it. Read on to find out.

1. Cotton Underwear

Big underwear manufacturers have been using cotton as their fabric of choice since forever. While it’s true that cotton can prevent your balls from getting all sweaty and gasping for air, the real reason why manufacturers love this fabric is because of how cheap some of its blends can be. The cheaper the fabric, the higher the profit margins.

Now don’t get us wrong. There are premium blends of cotton out there that look and feel great. But you’ll have a hard time finding those, unless you’re willing to splurge like a teenager with a brand new credit card.

Put another way, cotton is the vanilla flavor of underwear fabrics. It’s pretty decent in almost every way, but nothing special.

2. Silk Underwear

From the royal robes of ancient kings and queens to the plush lingerie lines of today, silk fabric is the epitome of luxury. It’s easily one of the most comfortable and breathable fabrics out there. You can’t go wrong with silk if you have sensitive skin, live in a hot area, or both.

So why is it that every dude out there isn’t wearing silk fabric undies already?

There is but one problem. You see, where silk shines in keeping things cool and breezy, it utterly fails at giving your package the support it needs. Not to mention, silk can crawl up in areas you never thought possible.

And that’s exactly why silk isn’t the fabric of choice for men's underwear.

3. Merino Wool Underwear

Here’s a fun one. If you’re looking for the fabric that can suck your balls dry (of sweat!), merino wool will do it better than anything else out there.

Better yet, it’s nothing like the regular wool you may have worn before. The fine and soft fibers of this fabric are quite comfortable and free of any itching whatsoever.

Sadly, that’s where the good part ends. While merino wool is softer than regular wool, it’s no match for silk or even cotton. Anyone who says otherwise is probably exaggerating.

Plus, as merino wool fabric drinks moisture but doesn’t give it up easily, you’ll be left with moist undies if you sweat a lot — especially on a hot summer day. Good luck suffering through that!

4. Bamboo Underwear

If someone asked you to think of a light and silky fiber, bamboo is probably the last thing you’ll ever think of. But don’t let this sturdy plant bamboozle you.

Bamboo fabric is actually lighter and softer than cotton. Plus, it can wick moisture and let air pass through almost as well. But what truly sets bamboo fiber apart from most fabrics is its antibacterial properties. Not only does that prevent a nasty rash, but it can also keep your crotch from turning into a scent bomb.

In short, bamboo underwear is better than cotton without a doubt. But is it the best men's boxer brief fabric out there? With its strong smell and slow drying time — not quite.

5. Spandex Underwear

Spandex is a lightweight, durable, and moisture resistant fabric that you’ll find in every pair of men's underwear out there. That’s because, above all else, spandex is elastic, which explains why the fabric is actually called elastane.

Spandex can stretch and endure worse conditions than rubber. So if you’re into sports or just a fitness freak, this elastic fabric will keep you supported all the way — whether that’s lifting your butt or hugging your nuts.

Just don’t expect to keep these on for the rest of your day. That’s because spandex will stifle your manhood by trapping heat and moisture. As it gets sticky, it can turn into a pain in the ass — both figuratively and literally.

6. Polyester Underwear

Here’s a fun fact. Polyester was made specifically to serve the needs of the male body. It can survive all sorts of wear and tear. It’s resistant to shrinking, fading, and wrinkles. And it’s so thin it puts cotton fabric to shame (think half the thickness)!

Sounds like the perfect material for your next underwear, right?

Well, as with most things in life, there is a catch. As a synthetic material, polyester suffers the same fate as spandex. It can trap heat and moisture, making it far from ideal for daily wear.

Oh, and did you know this man-made fabric is filled with harsh chemicals that can wreak havoc on sensitive skin? Now you know!

By this point, you probably think there’s no such thing as the perfect fabric for men's underwear. Well, it’s time to think again.

Micro Modal fabric is more moisture-absorbent than cotton, soft like silk without the slippery, antibacterial and resistant to shrinkage. In comfort it beats out anything else on this list — all with a natural blend of fibers.

You won’t find a more breathable pair of underwear out there. With Micro Modal underwear, it feels as if you’re wearing nothing while your babymaker gets all the love it needs to thrive.

You’d think a fabric like that would cost a fortune. But the truth is, you don’t have to become a stripper to afford this magical fabric. Check out our boxer brief collection to see for yourself.
