Stay-cool underwear options for the hot summer months.

Man staying cool wearing breathable briefs.

Whether you live in a warm climate, or the summer months are starting to roll around, a high-quality pair of breathable boxer briefs is underwear that you’ll never regret reaching for in the drawer.

Because we’ve all felt it before.

The swampy, pooling of sweat in our seat (commonly known as “swass”) that leaves you damp, sticky, and miserable.

But if you thought this was an unfortunate reality that you were resigned to live with, here’s some good news for you.

Swass is a treatable discomfort.

For reasons unknown, underwear has been an overlooked and underappreciated factor in staying cool.

It certainly shouldn’t be, however, as it’s the first thing you put on and the layer that rests right against your skin.

It makes perfect sense that when you incorporate breathable fabrics and garment features into the design of underwear, it can help to regulate body temperature and wick away moisture.

This in turn helps you stay cooler and drier for longer, whether you’re out in the sweltering heat or simply going about your everyday routine.

Here, we’ve rounded up the best breathable brief options for hot weather in 2024.

Stock up on your favorites and stay cool this summer.

How We Make Our Picks for Best Breathable Briefs


Every pair of underwear falls somewhere on the breathability spectrum.


Lots of underwear brands claim their briefs have great breathability but certain options certainly perform better than others.


From extensive testing of men’s underwear options in hot and humid circumstances, we’ve found that 2 characteristics significantly boost underwear breathability.


1. Extra Lightweight Fabric 


When the temperature rises and your body starts to sweat, there’s nothing worse than damp and heavy fabric sticking to your body.


The weight of the fabric before it gets damp and how it handles sweat will play a big role in overall breathability.

Extra lightweight fabric on briefs.
Tommy John Air underwear features incredibly lightweight mesh fabric.

Typically, the best option is going to be a mesh fabric or a naturally breathable material with a permeable construction.


Not only does the permeability of these fabrics allow heat and sweat to move away from your body but it also helps your underwear dry faster. 



2. Strategic Ventilation


The major obstacle in designing breathable underwear is creating a garment that maintains its structural and functional integrity.


In other words, underwear that’s super lightweight and permeable is useless if it doesn’t perform the other necessary features.

Strategic ventilation on briefs used for breathability.
Mack Weldon AIRKNITx underwear utilizes strategic ventilation for improved breathability.

This balance can be achieved through strategically placed ventilation in optimal spots.


Adding ventilation to the spots where it’s needed most will go a long way in keeping you cool while still offering other key aspects like comfort and support.

Here's What to Look for When Buying Breathable Underwear

When the hot summer months arrive, keeping cool becomes a priority for everyone.

One of the best ways to beat the heat can be found in your clothing choices.

Breathable garments, including underwear, help tremendously with your body’s ability to regulate temperature and keep from overheating.

While cotton fabric has long been considered the most breathable choice for underwear, fabric type is really just one aspect to consider if you’re looking for breathable underwear options that will keep you cool and dry.

For example, think about what happens to cotton when it gets wet (i.e. when you sweat).

The fabric gets damp and heavy, absorbing the moisture rather than dispersing it.

Underwear that also takes sweat and moisture management into consideration will help you stay cooler and drier for longer.

Because it’s not that you don’t want sweat to happen. Sweat is a good thing. It’s your body’s natural process of cooling down.

So, when browsing for breathable underwear to help you stay cool in hot weather, keep an eye out for underwear designed to assist your body’s temperature regulation process.

Look for underwear with breathable fabrics and design elements, such as cooling vents or breathable mesh, as well as sweat-wicking technology that will remove moisture from your skin.

This combination of design features, both the breathable and the moisture-wicking, will help you stay cooler, drier, and more comfortable in hot conditions.
