I'm pretty sure no one likes the feeling of a warm, damp butt, but it turns out that sticking to the best breathable underwear can be important to your health down there, too. Ideally, you want more airflow and less trapped moisture, especially if you're working out or rushing to catch the train in the morning. The bad news is that a lot of underwear that looks thin and breathable really isn't — this is due to synthetic fibers that trap heat and sweat. But the good news is that just about any style of panties can be found in a breathable fabric.
For the most part, the more natural the fabric, the better it is for airflow. That's why cotton underwear is pretty much the gold standard of breathable underwear, and bamboo is also a solid lightweight choice. That being said, some synthetic underwear compensates with a lightweight mesh design that allows for more airflow, which can be just as good as natural fabrics when done correctly.
Basically, whether you're looking for underwear you can workout in or a pair that's just super comfortable for everyday wear, you'll find it here. These are the best breathable underwear the internet has to offer.
