One of the main causes of sweaty balls – if you are a man – or excessive sweating between your legs (groin area) if you are a woman, is the type of underwear you wear. You may think this is pure nonsense but start checking the labels of your garments so you can see what they are made of.

If the underwear you're currently wearing keeps you wet all the time, it's time to change it and you will realize that having the right underwear is a game changer.

Maybe you are wearing cotton underwear right now, the best known material for being a textile fabric of great durability. Cotton has a remarkable softness to the touch, which is very pleasant to use. You will feel a cozy and protective feeling when wearing any type of cotton garment. But this fabric is not the ideal one  if you have problems with sweat and body odors, so It is better that you read and discover which is the underwear that absorbs more moisture and what material they are made of.

If your balls or groin area are always sweat and you can feel your smell through your pants, you are in a big trouble... But don't worry, everything has a solution!

There are sweat-wicking underwear that are made of super-breathable fabric that allows sweat to wick away from the skin and dry almost as fast as it forms on the body. This gives men or woman the chance to focus on their active days without irritated, wet nether regions. Alternatively, sweat proof underwear is designed to help prevent sweat from leaking out onto clothing.

Is Polyester Breathable?

Polyester is a well known fabric in the workout and active clothing line because of its lightweight and breathable structures. It is breathability that contributes to being a water-repellent material, making the skin's moisture evaporates quickly.

However, cotton is a lot more breathable than polyester but  polyester is moisture-wicking and will keep you dry when you are sweating. Cotton is highly absorbent and will show sweat patches.

Regarding synthetic fiber underwear, these are manufactured through oil-based chemical processes. Polyester is the most common synthetic fabric that can be found in underwear. Its qualities include heat resistance, are quick drying, shrink very little and do not wrinkle, it is also much more elastic than cotton. In addition, polyester has the characteristic of transporting moisture from the body out, evaporating it without adhering to the material itself.

We made an exhaustive review of many brands of men's and women's underwear and we made a list with the most absorbent. We notice that most of them are composed of polyester, Merino wool or bamboo fibers.
