3 Tips for Buying the Best Men's Athletic Underwear
1. Try Several Pairs
The first place to start? Look at your own anatomy, Dr. Shaw suggests. Everyone's body is different and y0ur best pair of men's workout underwear will depend on your personal needs.
"Do what's right for your body," Dr. Shaw says. "There's this whole boxer and brief debate, but there's no one answer that's right for everybody. Experiment and buy a couple of pairs and see what feels right for you."
Keep in mind that testicles are about a degree or degree and a half cooler than the rest of your body, which is why they sit low, Dr. Shaw says. Considering that everyone's testicles sit at different heights, it's best to try several pairs to find your perfect fit.
You definitely want support in your workout undies, but you shouldn't feel like you're squeezing into them. A pair of underwear that compresses too much can be uncomfortable and problematic for sperm production. Look for men's workout underwear that lets you move freely in every direction without too much loose fabric.
2. Look for Moisture-Wicking Fabric
Keeping your crotch dry is crucial for avoiding skin issues like jock itch, chafing or infection. That's why you should look for fabric that's breathable and pulls moisture away from your body. Although cotton is comfortable and breathes nicely, it usually stays damp, according to Dr. Shaw.
Nylon, polyester, Merino wool and bamboo are more breathable and sweat-wicking materials you want in your workout underwear, he says.
Most men's workout underwear have a blend of different fabrics, so read the packaging closely and look out for these materials. Even a cotton pair that's blended with one of these performance fabrics should be fine for working out.
3. Consider Your Activities
The type of workouts you do will play a big part in your underwear selection, Dr. Shaw says. Cyclists, for instance, should look for a pair of longer, compressive boxers so they won't bunch up in the middle of a ride. Yogis might prefer a pair that's especially flexible, while runners may want ones that have a no-slip waistband.
