If you wear the wrong underwear on long runs, it can feel like your nether region is on fire. You can get painful chafing that will make you reconsider your training goals. Instead of giving up, you should look for the best underwear for running to help solve the problem.
Quick Look: Our Top Picks
Why Does It Make a Difference What Underwear I Wear?
While you and your running buddy may freely share tips about the best shorts or shirts for running, I bet you haven’t discussed underwear yet. Mentioning unmentionables is still a big deal for some runners. But the underwear you select can make a big difference, even if no one usually acknowledges it.
You wouldn’t dream of wearing a regular t-shirt and sweatpants on a long run, so why do you think it’s okay to grab any pair of underwear? Like everything else on your body during your runs, your underwear should be selected with performance in mind.
Do I Need to Wear Underwear?
Underwear isn’t a requirement for running, but many runners prefer wearing them to going commando.
Running tights are very form-fitting, which makes some runners uncomfortable at the thought of running without underwear. They can’t keep their head in the race because they’re spending their energy wondering if other runners can see through their tights.
Why Kind of Fit Should I Be Looking For?
Your running underwear should be form-fitting and comfortable. You don’t want anything too loose because you may need to keep adjusting it during your run and it will contribute to chafing.
Likewise, you don’t want anything that’s overly tight. That will feel uncomfortable and it will create an unflattering muffin-top situation, even on thin runners.
You want to find that perfect Goldilocks zone when it comes to how snug your underwear is.
What Time of the Year Are You Running?
Even if you opt to go commando in the summer, you might want to give some serious consideration to having running underwear around for winter runs.
For one thing, while many running shorts have built-in liners, that’s less common in tights and pants. And then there’s the factor of the weather itself.
When you run in the winter, every part of you can feel the nip through the breathable running clothes you wear. Even when you dress in layers for the upper body, the lower body tends to get stuck with just one layer.
On windy, cold days in particular, if you don’t wear underwear, it can be really uncomfortable because of how brisk things get. And if you’re on a long run without underwear, the thought of having frozen private parts can be enough to make you turn around and call it quits for the day.
What Kind of Fabric Should They Be Made From?
As a runner, you probably already tend to avoid cotton clothing on your runs. That’s a good rule to follow as well when it comes to your underwear selection.
Cotton drinks up the sweat and takes a long time to dry, which can lead to a colder feeling and chafing. Instead, look for a material that’s made out of wool or is synthetic.
What Are Some Features My Underwear Should Have?
While it’s weird to think of underwear as having special features, when it comes to running gear, everything is made with a purpose — even your underwear.
Here are some of the features you’ll want to look for:
- Breathability: You’ll want air to circulate down there when you run, particularly if you are a heavy sweater. There’s nothing worse than soggy-feeling underwear when you still have miles to go. You start to feel like a little kid who couldn’t make it to the bathroom in time.
- Windproof panels: Male runners who plan on doing much winter running may want to consider looking for a windproof panel on the front of their underwear. That will offer protection from the harsh wind.
- Seams: You’ll want to watch the seam situation on the underwear you’re considering. If it has thick seams, it will be uncomfortable for the long haul. You’ll want to keep seams and their size to a minimum for added comfort and fewer panty lines showing through form-fitting running tights.
- The fit: If low-ride underwear drives you crazy, you’ll want to look for something with a bit more coverage. If you don’t enjoy the fit of your underwear, they’re not the right pair for you.
- Appearance: The other runners won’t be seeing your underwear unless you have a wardrobe malfunction with see-through running tights. But that doesn’t mean you can’t still have fun with your underwear selection. Look for a fun color or something with an inspirational message on them.
- No tags: Running underwear should be tagless for added comfort.
