Ultimate Guide to Choosing the Best Men’s Underwear

In the past, when it comes to underwear for men, we can master by just answering one and only one question: briefs or boxers, right? But up to now, there have been hundreds of types, kinds and designs with different fabrics and attributes. To know which one is the best men’s underwear for you, might you need a team of researchers.

Thus, in this article, I will give you the ultimate guide to choosing the best underwear for men as well as answer top underwear questions that we’re usually embarrassed to ask.

How to choose the best men’s underwear


I know that some of us usually choose underwear in a very small size to emphasize their front. However, it only causes discomfort, sometimes is painful. And if you keep wearing such tiny underwear in long time, it will cause fertility and health problems. Besides, too tight elastic waistband causes crashes and irritation.

On the contrary, if you wear too big underwear, some unsightly wrinkles will be showed in the outer clothes, which is aesthetic loss.

Like pants, underwear’s size depends on your waist circumstance. If you don’t have time to remeasure your waist, using your pants’ size is okay.

Below are underwear’s sizing charts:

Waist (inch) 28-30 32-34 36-38 40-42 44-46 48-50 52-54 56-58


Not only size, but also the fabric impacts greatly on comfort of the underwear. When choosing men underwear, you should consider which are soft, air flow, movement, warmth and support.

In general, there are two main kinds of underwear’s fabric: synthetic and natural materials. And each certain kind will fit well either physical activities or sleepwear. Sometimes, we do divide underwear into two kinds to put on in cold and warm weather due to the fabric.

Knowing a little bit about each kind of material as well as their consideration will help you choose the best men’s underwear for particular demands.

Material Considerations
Wool There are different degrees of quality when it comes to this natural material. While the low grades cause excessive sweating and itchiness to users, the high quality is soft, breathable and warm.

Thus, they are usually used as thermal underwear or in the winter.

Flannel This is an interesting combination of synthetic fiber, cotton and wool. They are soft but not durable and strong. In fact, flannel underwear is easily torn and has holes over time.

They are usually used as loungewear and thermal underwear.

Cotton They are natural material, like wool. Cotton is the most comfortable and softest. Different weaves provide air flow in hot days and warmth in cold days.
Silk This is a luxury material and often used for boxers. They are soft but easy to get stains and can’t stand moisture. Thus, many manufacturers usually use an alternative material imitating silk (usually is synthetic fibers) to make more durable underwear with stylish designs.
Spandex This is a synthetic material and usually used as athletic underwear because it can stand strong movements and have high flexibility. However, as they are usually used for athletics. They can’t trap odor or sweat.
Nylon This is a synthetic and stretchy material. Nylon is silky, long lasting and creates sexy feeling. Thus, nylon is usually used to make sexy kinds of mens underwear like thongs, bikini and boxer briefs.


There are a lot of mens underwear brands offering various styles, types and designs with different fabrics, features and cuts. Some concentrate on the comfort while the others cater to the latest trends in underwear fashion. Usually, a particular brand will give you the perfect fit that no others can. Thus, to find out the best men’s underwear fitting properly, let’s try a few different brands.

Some famous names you can consult are Hanes, Fruit, Calvin Klein, Tommy, etc.


Last but not least, it is type. Choosing a mens underwear type is not only based on your favorite, but also due to your body shape.


If you are not a kind of guys who like to wear underwear sitting snug against your skin, but the one offering maximum breathability, go for some boxers. In turn, this type won’t support much down there.

In the past, boxers were usually for teens with elasticated waist, baggy cut and bunched. These days, alongside such traditional versions, many designers have redesigned them with stretch waistband, slimmer and shorter-cut options. From that point, those new versions are suitable for men with thin thighs.

On the contrary, for guys with muscular legs, they might not a wise choice because the crotch’s low cut will be tricky while you are walking. And if you wear with trousers, the down there can’t sweat. More seriously, it is potentially painful.

However, because of high breathability, you can use them as sleepwear. Go for a 100% cotton boxer made of solid pattern or cool fabric with tailored and trim waistband and you won’t regret it.


Forget those old-version briefs that your mom bought when you were young. Briefs has had a big revolution for its design and up to now, they are much sexier and stereotype-breaking. Due to its shape, you can guess why Cristiano Ronaldo or David Beckham worn it in campaigns. Briefs are an ideal choice for men with thick thigns.

This type is also good for short-leg guys because it will expose your legs more, which makes they look longer and you, of course, seem to be taller.

Besides, if you tend to choose briefs as your casual wear, go for a 100% cotton. On the contrary, a brief with technical material is perfect for your workouts or athletics as they help to wick your sweat away. And keep in mind that how fit of the brief on you depend on the cut leg holes at particular angles.

For example, if you are a man with small butts, a brief with slimmer material’s section underneath the waistband will fit well on you. On the contrary, a big-butt guy should look for a brief with more material at the back of the pants.

However, say “no” to man-man fibers if you don’t want to get a rash in your down there.

Boxer briefs

Its name says everything! This is a lovechild of briefs and boxers. This type is considered as the most versatile because it still offers all the support of briefs but also not as revealing as them thanks. We can say that it fits most of men’s shapes from mid to low thighs and the truth is, nowadays, it is a go-to trend of gentlemen.

Especially for guys with more to store back there, boxer briefs overcome the drawback of briefs of covering such big butts. With the fabric sitting snug against your skin stretching over the legs, they give the ideal halfway house.

Boxer briefs usually have a button fly, which means that it becomes another favorite underwear for thick thigh guys, alongside briefs. Besides, the fabric added between your legs will prevent chafing or rubbing. However, if you tend to choose such kind of boxer brief, be wise to choose the best pair. Choose a boxer brief with longer length, but to avoid it bunching up after you put on your trousers, make sure it’s not too tight.

In a word, boxer briefs are suitable for guys with larger posterior and tall men.


This is the latest style of this list, which fits well on slimmer men with mid – to upper-thigh or those who are gym-honed. Guys with thicker thighs may find them rolling up while walking, which is unpleasant.

In literally, they are the shorter version of boxer briefs. They become famous alongside the growth of the super skinny trousers over a past few years.

Some designs are flat-fronted while some have keyhole fly. Sometimes, a few models have an extra pouch at the front to add some more enhancement and support.

Top questions about underwear that you’re usually embarrassed to ask

How often do I wash my underwear?

I’m really surprised that many of us ask this question because the answer is super easy – when it’s dirty. Even if you are living a desk – job life, after a day wearing, your underwear will become uncomfortable and need to be replaced. That is not mentioned in active days when you do strenuous gym session or join some physical sports, you sweat pretty much. In such cases, your underwear will absorb moisture from your body and start to smell. Thus, practice wash them after each wear and good hygiene is a good habit.

Which style is the best?

The most popular choices are boxers, briefs, boxer briefs and trunks. Never go for a commando, please! However, to point out which is the best underwear style is a subjective answer as it depends on your personal favorite and your body shape.

In my opinion, I like boxer briefs because as I said, they are the lovechild of briefs and boxers, which means they are a mix of all pros from both styles. For examples, they are comfortable but still sitting snug against my skin; not as revealing as briefs but still sexy and covering greatly.

Besides, it is also based on which style of the outer clothing you intend to wear, like boxers for loose trousers and briefs for skinny jeans or tight pants.

Which fabric is the best for mens underwear?

Again, this is a subjective answer because it dues to many elements like how sensitive of your skin, which purpose you wear it for or the weather. For example, if you have sensitive skin, I would recommend you to use cotton underwear because they are soft and very comfortable. Depend on particular production, they can keep you cool in the summer and stay warm in the winter.

On the other hand, if you are an active man who usually participate in physical activities, go for spandex mixing with cotton underwear to increase their durability and flexibility. For those guys who want some fashionable and luxurious underwear, give the silk or nylon a try. It’s worth it!

When is the time to throw away my underwear?

Good question! Never keep your underwear until it shreds in your washing machine. And never donate your old underwear. Bear in mind this rule of thumb, men should replace his underwear at least once a year.

Begin with those faded, saggy and jaded underwear. Next are the ones with visible stain or holes in them. Underwear with loose elastic waistband should be also replaced and the lastly, for those underwear that doesn’t fit your body shape anymore because of you gaining or losing weight should be thrown away. Don’t keep hoping that one day, they will be fitted if you return to your original body shape.

Should I go for specialty underwear?

You can try the specialty underwear but never put on a too-small size for the purpose of emphasizing the front to impress your surrounding girls. It will end up the maximum discomfort and itchiness. In serious cases, it might cause some health problems.

If you intend to get some specialty underwear, here are some advice:

  • Package separator
  • Posterior enhancers
  • Compression

Women and girls find mens glutes are the 2rd sexiest parts on the body so that if you don’t have butts, think about underwear that can support the back well to make your glutes seem fuller.

Above are all about underwear. Which parts are useful for you the most? I hope that through this article, I have given you some interesting and helpful information so that you can choose the best mens underwear for your wardrobe.
