Once you've stocked up on shorts, leggings, and fitness tops, you'll want to buy some great workout underwear to complete your outfit. “Comfort is a key factor to having a feel-good experience while working out,” says Shayra Brown, NASM, personal trainer at Blink Fitness. If your underwear is bunching, riding up, or moving around while you work out, it's hard to feel comfortable.

Underwear worn during exercise needs to be tight enough to not slip around, but not overly constricting. You also want to consider your underwear material. “Look for fabric that wicks moisture away from your body, so moisture does not accumulate in your crotch area,” Annette Dale-Kramek, activewear designer and founder of Ancient Language 97, says. She recommends stretchy fabrics that are lightweight, breathable, and moisture-wicking. She also explains that cotton should be avoided because it retains moisture.

Here are the best pairs of underwear for working out on the market.

Stretchy and comfortable, they feature a crossover waistband designed to sit under your baby bump. They're also crafted with a flexible blend of rayon and spandex that forms to your body as it changes during pregnancy.

Thinx blends comfort and protection in a low-profile pair of sport period panties. Crafted with a blend of nylon and elastane, they're designed to stay in place while you work out. They also feature a breathable cotton and elastane gusset to keep you cool and comfortable throughout the day.

Since they fall under the category of period panties, they'll feel thicker than most athletic underwear. However, this helps them absorb liquid at a moderate level. Though the period products you use are ultimately up to you, this kind of absorption means you might be able to forgo pads during workouts—without increasing your risk of a leak.

Material: Nylon, elastane | Gusset Material: Cotton, elastane | Colors: Four | Sizes: XS-4XL

Pros

Fuller coverage
Seamless, tag-free waistband
Leg openings prevent chafing and bunching
Odor-controlling fabric

Cons

Limited color options
May run small

Patagonia's Active Briefs will give you more support than you’d find from a skimpier pair of workout undies. But since they’re crafted from a blend of recycled polyester, nylon, and spandex, you can still expect them to feel lightweight, breathable, and stretchy.

Since the briefs boast a seamless, tag-free waistband, they cut down on itch and discomfort as you work out. The leg openings are also designed to stay securely in place—minimizing the chance that they'll ride up, chafe, or bunch. To top things off, they're made with Polygiene odor control technology to cut down on bacteria and post-workout stench.

Material: Polyester, nylon, spandex | Gusset Material: Polyester, nylon, spandex | Colors: One | Sizes: XS-XL

Pros

Comfortable stitch-free design
Breathable cotton gusset
Wide variety of colors

Cons

May ride up
Gusset may be too narrow for some
May loosen with use

ThirdLove’s Comfort Stretch Thong is comfortable, stretchy, and available in a wide range of sizes and colors. The thong is crafted from a stretchy blend of nylon and spandex, so it should flexibly move with you as you exercise. And thanks to its breathable cotton gusset, it promises to feel pretty cool, too.

This style boasts a stitch-free design, which means less discomfort and fewer panty lines. It also comes in an inclusive size range and 11 colors, so you shouldn't have trouble finding an option that works for you.

Material: Nylon, spandex | Gusset Material: Cotton | Colors: 13 | Sizes: S-3XL

Pros

Breathable cotton gusset
Available in 13 shades

Cons

Size range varies by color

Even if you buy "no-show" panties, they might be visible if they don't come close to matching your skin tone. Unfortunately, many seamless panties are only offered in a couple of nude tones. Nude Barre’s Seamless Bikini Panties come in 13 shades to help solve this issue.

They're crafted with a blend of polyamide and elastane and they feature a breathable cotton gusset to keep you comfortable during your workout. The seamless design ensures they won't dig into your skin, and they're snug enough to stay in place as you move.

Material: Polyamide, elastane | Gusset Material: Cotton | Colors: 13 | Sizes: XS-XL

Sweaty Betty Mindful Seamless Hipster Briefs

Pros

Comfortable seamless design
Thicker than most no-shows
Lightweight, breathable, and moisture-wicking

Cons

May give you pantylines

Visible panty lines aren't the only reason you might want to avoid seams. Some prefer seamless underwear to avoid digging and irritation from stitches on the material. Sweaty Betty’s Mindful Seamless Hipster Briefs are perfect for the person who wants a seamless panty, but who also craves more support than no-show panties tend to provide.

Crafted from Lenzing yarn, the briefs should feel soft to the touch, and thicker than your average pair of no-show panties. But thanks to their ribbed design, you can also expect them to feel lightweight, breathable, and flexible enough to work out in. True to form, the seamless undies offer the full, supportive coverage you’d expect from a pair of briefs, and their cozy design makes them a great pick for both exercise and everyday wear.

Material: Lenzing yarn, polyamide, elastane | Gusset Material: Lenzing yarn, polyamide, elastane | Colors: Three | Sizes: XS-XXL

Final Verdict

They have a stretchy composition that stays in place while you're moving, but they're also cozy enough to wear for daily use.

Another great choice is Lululemon's InvisiWear Mid-Rise Thong (view at Lululemon) which is crafted with nylon and elastane to provide a smooth and stretchy feel. Flexible enough to allow for a full range of motion, they're also snug and will stay in place when you exercise. The fabric also wicks away moisture keeping you cool and comfortable.

What to Look for in Underwear for Working Out

Material

How a pair of underwear feels counts for a lot. That's why you'll want to pay attention to the list of materials in a pair of workout underwear to ensure that it will feel comfortable during your practice. You want something that's lightweight, breathable, and moisture-wicking—keeping you comfortable and cool when you work out. You also want a pair that will provide a snug but flexible fit. Opting for nylon or spandex is a good choice.

According to Dale-Kramek, while cotton is a popular choice, it may actually hold onto moisture. So if you’re in the market for something moisture-wicking, you may be better off with a synthetic textile—like polyester or nylon.

Gusset Material

When shopping for workout underwear, you may notice that the word gusset comes up again and again. Simply put, the gusset is the piece of fabric lining the crotch of the underwear. And since it’s designed to brush up against some of the most sensitive skin on your body, it’s often crafted from a different material than the rest of the underwear. (The underwear may be made of stretchy synthetic fabric, whereas the gusset may be made of cotton.)

Cut

Workout underwear is available in a range of different cuts—including thongs, hipsters, briefs, and more. Skimpier options, like thongs, may cut down on visible panty lines. But according to Dale-Kramek, they may also irritate your skin. Fuller coverage options, like briefs, can be great if you’re looking for more support. But since they feature more fabric, they may bunch up, add bulk to your workout bottoms, or cause panty lines.

Seams and Tags

A lot of workout underwear is designed without seams or waistband tags to make them more comfortable and less visible. “Seamless may be more comfortable across the board,” Dale-Kramek says. (That said, she notes that seamless underwear may not be as necessary as we make it out to be.) She also recommends finding something “simple, lightweight, and airy” above all else.”

Colors

Workout underwear comes in all kinds of different colors—some nude, some neutral, and some vibrant. Though color is ultimately a matter of personal preference, you may want to consider the opacity of your workout bottoms when shopping for underwear. (A pair of vibrant underwear is likely to show through a translucent pair of leggings.)

Frequently Asked Questions

Should you wear underwear when you work out?

If you want to stay comfortable and reduce your risk of infection, it may be a good idea to wear underwear while working out. Why? Sweating is a normal part of working out. But if that sweat pools in your crotch area, it may make you uncomfortable—and it may also increase your risk of infection.
For this reason, it’s important to make sure you’re wearing something that will wick moisture away from your crotch as you exercise. If your workout bottoms are adequately moisture-wicking, they may take care of this for you. But if they aren’t, you may need a pair of underwear to make sure sweat isn’t pooling anywhere it shouldn’t.
Is it bad to wear thongs while working out?

Thongs are a popular choice in the workout underwear space. After all, they’re unlikely to cause visible panty lines—and since they’re so low-profile, they’re also unlikely to add bulk to your workout bottoms. But Dale-Kramek advises against wearing thongs while working out because they can ride up and irritate your tush.
