The Best Breathable Boxer Briefs for Hot Weather 2025

Stay-cool underwear options for the hot summer months.

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.

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 boxer brief options for hot weather in 2025.

Stock up on your favorites and stay cool this summer.

Here's how we make our picks for Best Breathable Boxer Briefs.

Every pair of underwear falls somewhere on the breathability spectrum.

Lots of underwear brands claim their boxer 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 two 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.

The Tommy John Air Boxer Briefs feature 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.

The Mack Weldon AIRKNITx Boxer Briefs utilize 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.
