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 boxer brief options for hot weather in 2022. Stock up on your favorites and stay cool this summer.

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.
