Looking for the most comfortable women's underwear, period? Look no further. This thong is made with a nylon and elastane fabric blend that's so stretchy, your body can move in any direction without unwanted constriction. If your regular workout routine ends in damp underwear (hey, it's normal), you'll also appreciate that the blend is sweat-wicking for a quick dry. Plus, the ultra-tight compression fit and laser-cut edges mean this pair won't give you panty lines — even under your sheerest leggings. There's even anti-odor technology, so you'll stay fresh as the underwear prevents the growth of odor-causing microbes.

One five-star reviewer who had "never worked out in a thong before" was skeptical about the comfort, but said they ultimately completely forgot they were even wearing them — they're that comfy.

Best Cotton: Amazon Essentials Cotton Bikini Brief Underwear

FYI: You don't want to wear cotton underwear for high-intensity workouts where you sweat a lot, but a lightweight cotton pair is still a great option for low-key activities such as walks or yoga. The bikini-style cut on this pick gives medium coverage and ditches the tag to maximize comfort. Available in sizes XS-XL, these pairs are primarily made from super breathable cotton with just a hint of stretch from elastane. The budget-friendly buy is available in either a pack of six or 10, and comes in many different color combinations.

One happy owner said they replaced almost all of their underwear with this cotton underwear. They raved: "They are COMFORTABLE, come in CUTE colors and patterns, and most importantly they STAY PUT! I've worn them to work out and they are darn good for that, too. They wash and dry great, I haven't had any problems whatsoever."

Best Briefs: Sweaty Betty Barely There Briefs

The seamless design on these briefs won't just prevent panty lines, but it'll also prevent any friction between your skin and the sweat-wicking fabric. The low-rise cut also ensures your underwear won't pop out of the top of your favorite leggings, even when you're deadlifting or squatting deep. Plus, they're size-inclusive, offering up to size XXXL.

Oe review can attest it's all true: "These are simply 'the best' [underwear] to be wearing under SB leggings for all sports classes," they wrote, noting that they have a "comfortable, snug fit. Perfect!"

Best Hipster: Under Armour Women’s Power Underwear

You can count on this underwear to hug your body like a second skin during your workout — without uncomfortable squeezing. The laser-cut design ditches hems so you won't have to deal with any irritation, chafing, or unwanted underwear lines. Other comfort guarantors? Full booty coverage to prevent your underwear from riding up, a super soft cotton gusset, and tagless construction. There's even anti-odor technology to prevent the growth of microbes.

All things considered, it's no surprise one reviewer claimed these were actually "magical." They wrote that "everyone needs a pair" and confirmed they're super thin, comfortable, and panty-line proof.

Best Thong: Spanx Under Statements Thong

You shouldn't underestimate the breathability of this high-cut thong — it's made with a super lightweight fabric that's perforated for maximum airflow. The laser-cut edges also mean you won't deal with uncomfortable digging or panty lines. What's more, you can rest assured that these Spanx undies are not shapewear — no constriction here. In fact, this comfy pair is packed with moisture-wicking technology to make them even comfier to work out in.

An added bonus? One five-star review raved that this underwear is "a thong that will allow me to get through a barre class and squats without a 'vedgie' (aka front wedgie)." Say no more! (P.S. Spanx also makes activewear that is celebrity- and Shape-approved.)

There are plenty of benefits to bamboo fabric: It's super lightweight, sweat-wicking, and anti-static, to name a few. But if you have sensitive skin, the real sell is how soft the ultra-breathable fabric feels on your skin — try this pair of short-style briefs made with 80 percent bamboo fabric and see for yourself. Not only will you feel like you're wearing, well, practically nothing, but the fabric is also thermo-regulating, so it'll keep you cooler in the summer and warmer in the winter. Just be sure to check the size guide before you order, as some reviews say this underwear tends to run small.

One five-star reviewer on Amazon raved about their comfort and confirmed they "don't irritate" their skin and kept their body at a "comfortable temperature.

Best Antibacterial: ExOfficio Women’s Give-N-Go Sport Mesh Bikini Brief

The breathable mesh material is packed with silver ions that kill odor-causing microbes, while the fabric itself is also quick-drying. The low-rise, active fit gives you critical support without digging in, and they can even be washed in the sink and dry within two to four hours, making them a great choice for active travel.

A happy owner called these a great pick for their "great fit and breathability" and noted, "I've come back for more; they are super comfortable. Supportive without binding, and doesn't retain odor."
