Buying underwear can be a challenge for any guy. It’s a hit-or-miss game since you can’t fit underwear before you buy it. If it’s a hassle for regular guys, it’s a lot tougher for our plus-sized brothers.

So to help a brother out, we tested seven plus-size underwear to find the best underwear for fat guys.

But I’m a regular-sized bro, so how would I know which ones to pick? 

I’ve had my fair share of underwear problems too. From poor fit to chafing, we all have the same underwear concerns. It’s just that some are more pronounced for a specific body type.

Guys with a lot of extra pounds don’t always have an easy time looking for underwear that goes beyond 36 inches. Fit, moisture, and chafing are also the main issues that the best underwear needs to address.

And after doing my homework, it’s safe to say that Fruit of the Loom Men’s Coolzone Boxer Briefs for Big Man is the best underwear.

Though the “best” can be very subjective since not all widebodies are the same shape or size. But in terms of features that will make it comfortable for any big guy, it has it all. 

However, the rest of the products on this list are worth a look as well. So if underwear shopping has been a dread for you, it’s time to pick the right underwear and start feeling good inside and out.

Underwear Buying Guide For Fat Guys

When choosing underwear for big men, some considerations differ compared to underwear for regular-sized men. 

There are limitations when it comes to underwear type and special focus should be given to breathability, among other things.

So before you go underwear shopping, take a look at what’s important for a big guy’s underwear. 


Not all underwear types are suitable for a wide body. Guys with large bellies, thighs, and glutes need more space, breathability, protection from chafing, and excess moisture. This makes boxer shorts and boxer briefs ideal. 

Boxer shorts are the most refreshing option since it allows a lot of air in so your nether regions won’t feel hot and heavy. But they lack the support that you might need in some of your activities. 

This is where the versatility of boxer briefs comes in.

Boxer briefs give big guys the support and comfort they need the whole day. The design prevents your skin from rubbing against each other and other added features/properties can make it more enjoyable to wear.

Aside from these, briefs are also an option but only if chafing isn’t an issue for you. 

Trunks aren’t recommended because they fit too snugly and are very unflattering. And unfortunately, thongs and g-strings are out of the equation as well (sorry, fellas). 


I’ve already mentioned that bigger guys sweat more because of the excess body fat. And being sweaty down there is unhygienic and can potentially lead to bacterial infection. 

You can avoid this by choosing materials that are absorbent and wick the moisture out of your skin. 

It’s a great bonus if it also has antimicrobial properties like bamboo fiber has.

The material also affects fit and comfort. Elastic materials like cotton blends, spandex, and polyester provide a better fit since they contours to your body. 

These materials are also extra soft and won’t cause any skin irritation. The same goes for 100% cotton although you can’t expect elasticity and moisture-wicking features.


For big guys, the waist is a critical area for comfort and support. Because big guys have wide waistlines, the waistbands should be wide and elastic. 

Small waistbands will press onto your tummy and not in a good way. It should be wide enough to fit you comfortably and if it’s a tummy-controlling underwear, it should slim you down without pain or movement restrictions.

Elasticity allows the underwear to adjust to your body shape. 

If you’re very particular with this, some brands have softer waistbands than others. 

Also look for the tagless option since tags and stitches are a common source of irritation and discomfort.


This is a problem that many big men have. 

Your underwear should protect you from this through great fit and design. 

Boxer briefs excel in these departments because of how they fit closer to your skin and have legs that prevent your skin from rubbing against each other. Boxer shorts can also do this for you as long as they’re not too loose.

Comfort and Fit

Like with any underwear, comfort and fit are the basic functions that they should provide. And for guys with excess fat and wider body types, your underwear should hold everything (including your excess fat) in place comfortably. 

Fit can be a trial and error affair so look for brands that have a wide range of sizes or options specific to plus-sized men. 

Not all widebodies are the same, so it’s important to take note of which areas affect your size. 


All the underwear listed here are great options and each one brings value to plus-sized men. But for the best underwear for fat guys,  Fruit of the Loom Men’s Coolzone Boxer Briefs for Big Man takes the cake.

It checks all the boxes that big men need. 

Comfortable fabric, great fit, prevents chafing, value for money, and their Coolzone feature ensures you’re feeling fresh all day. 

It’s a reliable underwear for any type of daily activity.
