Luckily for you, antimicrobial underwear for men can fight the bacteria and foul odor since it’s built for resistance against sweat and fungus, eliminating any bacteria and improving your odor down there.

What To Look For In An Antibacterial Underwear?

These are my best tips when you are looking to buy antibacterial underwear.

Antimicrobial Material

Antimicrobial underwear is built to be resistant to bacteria and sweat. Some fabrics have natural antimicrobial properties (bamboo, merino wool), and others can be combined with chemicals to retard bacterial growth.

If you want to keep it the most natural, you can avoid exposing your balls and penis to chemicals and go for the natural choice of bamboo underwear.


Some antimicrobial underwear brands use silver ions that destroy the outer layer of bacteria, stopping its growth, and you smell fresh all day.

Silvadur technology is a more environmentally choice when compared with nanotechnology. If you care about the environment, you want to pay attention to the technology used on your underwear.

Silver technology effectively kills bacterias and fungus, but there is evidence that nanosilver can have some side effects on your natural bacterial balance.

No stink underwear, so you will buy the first antibacterial underwear you can find, and the job is done, right? Not necessary, because these days, you have a lot of antimicrobial underwear to choose from.

Learn how to get smell out your underwear here.

Keep in mind that you need to choose different styles for different activities. You might want to keep some antibacterial undies for the gym and others for some private workouts with your partner. Having smelly underwear on both activities can kill your confidence and reputation. It’s important to know how many pairs of underwear you need.


You also want to keep your comfort because underwear is something you use all the time (unless you are alone at home… it feels so good to go commando). Ensure your underwear is not tight and fits well. 

It doesn’t matter how many antibacterial properties the underwear has if it isn’t comfortable.

Yes, but you need to keep an eye on what materials are being used.

Best Antibacterial Underwear For Backpacking

If you are into running, fishing, hiking, camping, hunting, or anything recreational in the outdoors where scent control and comfort are essential, I would highly recommend Meriwool underwear.

If you use this underwear a few days straight, you will not feel the smell (remember this is perfect for multiple days on backpacking trips).

Unlike other textiles, Merino wool is a reactive material that adapts to your body’s temperature. It regulates so that you are never too hot or cold in any weather.

Merino wool has thinner, more delicate fibers that make it soft to the touch and cause no irritation to the skin. This underwear material is also ultra-soft, providing the comfort you need for outdoor activity.

Merino wool is one of the best materials for underwear (antimicrobial to eliminate odor, breathable and wicking to keep everything dry, soft for comfort).
