10 Best Men’s Underwear For Hot Weather and Sweat

Is underwear an afterthought for you?

For many men, it is. Just grab a pack of decent cotton briefs or boxers for $5 from Walmart and you’re good.  After all, it’s not a pair of shoes, a suit, or something else that many people will see every day.

We get it – it’s sound logic.

But there are a number of good reasons to invest in better underwear than what you’re wearing now. This is especially true when you’re living in hot climates.

There’s nothing worse than underwear made from low-quality, non-breathing materials riding up, bunching up, and making your life hell in a hot and humid climate.

We’re going to help you figure out what you need and what to look for when you buy your next pair (or several) of underwear. We'll also give you our top 10 picks for the best underwear for hot weather.

Top 10 Best Men's Underwear for Hot Weather

Now that you know what to look for, here are our picks for the 10 best men's underwear for hot weather:

1. Reebok Performance Boxer Briefs

Are you even wearing underwear? This three-pack of briefs is a good introduction to high-quality men’s underwear. They’re 90% polyester and 10% Spandex, with a breathable, contoured mesh pouch and no tag on the microfiber waistband. You can get them in several different colors, both muted and bright ones. 

What we found was that these briefs were thinner than others, providing us with the nice feeling that we weren’t wearing anything at all. The flipside to this is that they’re not able to handle a large amount of moisture before they overload and get damp.

A decent amount of physical activity, such as mowing the lawn or jogging for an extended time period, and they would get damp. For everyday wear, though, they’re great.

Let's get meshy: These boxer briefs are definitely snug, which is great for athletic men running, jumping, sprinting, and more. It keeps everything in place and the material – 91% polyester and 9% Spandex – is put together in a way that’s meant to reduce chafing from the stitching. 

It has a double-meshed support pouch. You can get them in various colors and styles, and the briefs come in two- or four-packs. They dry fast, and are ideal in situations where you might regularly get wet, such as in sailing.

3. Under Armour Original Series Boxerjock

A suit of armor: Under Armour boxer briefs are widely known and popular examples of high-quality underwear for men. The original series “boxerjock” briefs are made of lightweight and smooth synthetics, a mixture of polyester and elastane, with trademarked HeatGear technology wicking away sweat and help you feel light and dry.

This Under Armour product was designed specifically for wear in hot climates and environments. It gives your package ample support. That makes them perfect for when you’re exercising at the gym, running, or doing other intense physical activity. It’s no wonder that an Iraq veteran was a fan of these throughout his tours of duty. One potential downside is a seam down through the middle of the jock area – it could cause chafing in some wearers.

4. ExOfficio Men's Give-N-Go Sport Mesh Boxer Brief

Freshly baked: These boxer briefs are made of micro mesh fabric, but aren’t meshy around the crotch, something which many men prefer. A special antimicrobial treatment will help protect you from smells, and the 92% nylon/8% lycra mix means that these briefs will fit you comfortably and dry quickly after washing. 

They also have a functioning fly. The only problem that some people have reported is pilling – which means that the fabric will get stuck together.

5. Arc’Teryx Phase SL Boxer Briefs

Luxury undies: These Arc’Teryx men’s boxer briefs are black and classic – without a front seam down the middle of the crotch, they will nevertheless provide your package with comfortable support. A tagless waistband makes sure that you won’t feel the discomfort of a tag rubbing against your back or tailbone. We'll warn you in advance, they're on the pricey side.

6. Jockey Microfiber Performance Midway Brief

Free form: Made out of 20% spandex, these boxer briefs are going to be much more stretchy than others in their category. That’s good news for men who utilize the full range of motion of their legs and want their underwear to return to their original shape at the end of the day.

A no-gap H-fly means that you don’t have to fiddle with one side or the other when you go to the bathroom. Extra stitching has created seams that prevent the fabric from riding up the thighs, ensuring that you’ll be comfortable and dry when wearing these briefs.

7. 2UNDR Mens Swing Shift Trunk Boxers

Fly away: These 2UNDER boxers are crafted to give you the best wearing experience. The shrink-resistant fabric will stop the boxers from pilling and sticking together as a result of friction. With an ample codpiece area, these boxers will support you while not being too tight—an important balance to keep. 

They provide easy access to the front fly, and the waistband has been designed to be roll-resistant and stable. A great choice for active men for everyday use.

8. Champion Men's Tech Performance Long Boxer Brief

Championship caliber: These longer boxer briefs are great for those who struggle with sweaty thighs in hot conditions. With a construction that resists ride- and roll-up of the fabric, these Champion men’s long boxer briefs will make sure that men who struggle with upper leg sweat will walk around in hot climates in easy, relaxed comfort. 

Made from durable material, these briefs will last you a long time, keeping their shape and strength even with everyday wear and use.

9. Lululemon Game On Boxer Brief

Not just for ladies: All the ladies know about Lululemon leggings, but they haven’t been lazy with men’s products, either. These sleek, attractive boxer briefs will provide you with a comfortable, pleasant fit, and help you retain that comfort when you’re going about your day in hot or humid conditions.

10. Men's Armachillo Cooling Boxer Briefs

Play it cool: It’s microscopic jade embedded in the fabric and anti-odor treatment to prevent unpleasant smells that make these Armachillo boxer briefs cooling. The nylon/spandex material will pull moisture away from your skin, and keep you snug and dry when performing physical activity. 

The waistline is also a slightly heavier elastic than many other similar boxer briefs have, but it provides sturdiness and a sense that these briefs will last.

Most Comfortable Underwear for Hot Weather

Your underwear should also be well-designed for comfort.

That means it should have some construction that prevents ride-up (usually an elastic band at the leg-holes), a soft and tagless waistband, and it should be snug or loose, depending on how you wear it, but not too tightly-constructed. 

If the underwear is made with moisture-wicking fabric, then they shouldn’t be too loose. Otherwise, the whole point of the material would be lost!

So let's go over what's important in all the underwear we looked at.

• They’re all made out of a mix of high-quality moisture-wicking materials. 
• They all have seams that are sown in a way that reduces rub between skin and underwear as much as possible.
• Their waistbands are either traditional elastic, or some other lighter, newer material. But the most important thing is that the waistbands are stable and roll-resistant. 
• They’re all designed in a way that stops the fabric rolling or bunching up.
• And, most important, they breathe well. If the fabric doesn’t breathe much, your skin will always be too damp and sweaty, making moisture-wicking pointless. That’s why high-quality briefs are so important.

But all of the briefs we looked at meet the minimum in all these things, so you can’t go wrong with any of them!

Once you’ve made the change from regular to high-quality underwear in hot weather, you’ll wonder why you didn’t do it sooner. And men cursed by hot climates will be able to walk around freely and comfortably.

Good luck finding the right pair!
