Having a big belly and extra fat can bring a lot of complications when buying the proper undergarments, and that’s why you need to choose the best underwear for fat guys.

If you are here, you probably bought underwear that was too tight, not flexible, or supportive. It can happen if you choose the wrong design of underwear, the wrong fabric, or a pair that doesn’t have the right features to support the extra weight you have.

During a stressful day at work or a relaxed moment with the family, the last thing you need is uncomfortable underwear that keeps you from focusing on what you need to do. Issues such as friction, excessive sweating, or tight underwear can bring different health problems to fat people, and that is why it is essential to choose the best underwear for fat men, as each body shape and size have different needs.

Luckily for you, I have put a guide with the best underwear for fat guys and what you need to look for when buying undergarments for yourself.

What To Look For In Fat Man Underwear?

When buying the best underwear for big guys, you must consider five crucial features.


The style and design of your underwear is reasonably the most critical feature. For example, if you have a large waist, you want to buy boxer briefs or boxers, but if you have wide hips, you want to purchase trunks or boxer briefs.

Briefs tend to stretch fast when overweight and can crush your balls, providing more pain than comfort. It is a very supportive undergarment style, but I wouldn’t recommend it to fat men.


Boxer briefs are a great choice, especially if you don’t like when underwear rides up (who does it?). They prevent chafing and give support without your penis and balls feeling too tight. However, they can feel a little bit snug if you don’t buy a suitable material. Nevertheless, I still think this is the best underwear style for large men.

Boxers are a great option if you look for comfort and undergarments that don’t restrict your movements, giving you a certain freedom. Yet, boxers are not supportive and often not stretchy, so you need to buy the perfect size. In addition, the friction between the material and your skin can make chafing an issue.

As you can see, choosing the right design and style of your underwear, it’s crucial to avoid specific problems and getting the comfort you need.


The underwear material is also essential because you want to avoid materials that are not breathable or don’t provide enough elasticity. Again, you can check my guide on the best fabric for men’s underwear.

Some of the best materials are cotton (breathable and soft but can be absorbent if you sweat a lot), nylon (it keeps the underwear dry), or spandex (which is a flexible fabric). If you can find a pair of boxer briefs blended with the three materials, it would be perfect since they all work very well together. But, I would avoid 100% cotton-made underwear because it absorbs sweat and if excessive, doesn’t keep the underwear dry.

I would avoid silk fabric as it is very absorbent. I don’t have a problem with polyester because it’s a durable fabric, but I think you have better options like the three I mentioned.

The Fitting Of The Waistband

Some undergarments have a tight waistband with limited elasticity. That’s why having some made of spandex can be a good thing for you. Having a massive belly can make you uncomfortable, especially if you are wearing tight underwear.

The waistband should be soft and durable to give you the comfort and support you need. I had a pair of underwear that was so uncomfortable around the waist that I kept adjusting up and down all the time. Also, I had a rash around my waist, just so you guys understand the importance of a good-fit waistband.


Fat men tend to sweat more, feeling hotter and taking longer to cool down than lean people, so moisture control is significant.

Moisture can ruin your day since the accumulation of sweat can make your underwear heavy and smelly which could cause fungal infections. If you sweat a lot, I would consider buying antimicrobial underwear made of modal, merino wool, or bamboo since they have antibacterial properties.


I have mentioned chafing already, but I want to affirm how important it is to avoid it. You want to dodge any rashes or irritations in a sensitive area like your genitals. Breathable underwear and suitable fabric can make a huge difference in preventing chafing.

Top 5 Best Underwear For Fat Guys

These are, in my opinion, the best underwear for fat guys. I have avoided underwear made of 100% cotton.
