We’ve all done it. We’ve all made the mistake of wearing the wrong underwear for working out—dressed in the same cotton undies that we wore with our work office attire, regretting it just minutes on the treadmill or the elliptical. What we think might be a comfortable, efficient undergarment can very easily go the wrong way. The chafing, the bunching, the smell—with the wrong pair of underwear, things can get unpleasant very quickly. Life gives us enough challenges that get between our daily routines and squeezing in a proper workout. Your underwear shouldn’t be one of them.

While personal preferences may vary in terms of material, length, and fit, the general idea is to keep the goods secure and dry. That way, sweat won’t accumulate and harbor bacteria, which can lead to unpleasant odors or worse. The perfect workout underwear should feel like a second skin: close enough that it stays out of the way of what you’re trying to do but comfortable enough that it doesn’t restrict your movements.
Here, we’ve pulled together some of the best underwear for working out, so you can CrossFit, run, spin, or whatever you like to do without missing a beat.
What to Consider Before Buying the Best Underwear for Working Out:
There are enough questions out there surrounding workouts—which ones to try, how hard to go, and for how long—that selecting the right underwear should not be on your list of concerns. And while personal preferences may vary, and different activities may require slight variations, there are a few overarching themes to consider. Here, we’re breaking down the most important factors when it comes to the best underwear for working out.
Material: On warm summer days when you’re getting dressed for the company luncheon, natural fibers such as cotton and linen are your friend. But when it comes to pumping iron and clocking miles, natural fibers can be your enemy (for the most part). Our ancestors would totally think there’s some serious witchcraft going on with 21st-century underwear: Technical materials such as modal and polyester can wick moisture away from the skin and prevent the buildup of stinky bacteria, and even the way certain fabrics are woven—such as adding a little elastane to merino wool—can alter the structure and durability of natural fibers. Word to the wise for when it comes to the best undies for workouts: Avoid pieces that say they’re made of 100 percent of any natural fiber such as cotton, unless you want droopy, sweaty, swampy under layers.
Length: This pretty much comes down to individual preference—for the most part. Some people prefer the mobility and freedom of a brief or even a jockstrap, but others prefer the coverage and support of a longer boxer brief. Our best advice? Build up a stock of underwear so you’re ready for whatever life throws your way.
Fit: Again, considerations of fit have a lot to do with what you’re doing and how hard you like to work out. That said, most underwear for working out tends to skew toward the compression side of things. There is tons of evidence that compression-fit underwear can support performance, circulation, and recovery—but if you’re a guy who prefers to let things swing and breathe a little more naturally, you may want to choose something on the looser end of the spectrum.
BEST BOXERS FOR WORKING OUT
Ten Thousand A—L Boxer
Few brands understand the importance of fit and attention to the nitty-gritties quite like Ten Thousand. Built for maximum performance and maximum comfort, the brand’s A—L boxer uses a seamless build for the perfect snug—but not tight—fit. We loved this pair for the little details, which adds to the overall comfort, including the tagless construction and subtle embossed front logo, an ergonomic pouch, and the silky soft modal and spandex fabric.
Materials: Modal and spandex.
Inseam: 4 inches.
Style: Boxer brief.
BEST ANTI-ODOR UNDERWEAR FOR WORKING OUT
Mack Weldon Silver HD Boxer Brief
Mack Weldon is known for insanely soft fabrics, and its boxer brief is no exception. Every detail here has been carefully considered, from the no-roll waistband to the silky micro modal fabric. The best part? Each pair is treated with antimicrobial silver, which keeps these bad boys smelling so fresh and so clean even after your gnarliest sweat sessions.
Materials: Micro modal, nylon and spandex.
Inseam: 3 inches.
Style: Boxer brief.
BEST TRUNKS FOR WORKING OUT
Rhone Essentials Active Boxer Trunk
Do you find boxer briefs too covered-up and prone to bunching, and briefs too skimpy? Consider the trunk, a truncated version of a boxer brief that offers the best of both worlds. The fabric is soft and high-performing, but it’s really the no-roll, breathable jacquard mesh waistband that won high marks with us; it’ll keep, ahem, everything in place throughout whatever workout you throw their way.
Materials: Polyamide, polyester, and elastane.
Inseam: 4 inches.
Style: Trunk.
BEST UNDERWEAR FOR RUNNING
Tracksmith Brighton Boxer Briefs
Tracksmith knows running. The brand has made legions of fans for its popular tights and half-tights, and its new selection of underwear is a fitting offering for guys who prefer to layer underwear under their running shorts. These beautifully engineered boxer briefs make use of merino wool’s natural anti-stink and moisture-wicking properties and also feature a breathable, seamless construction that always supports and never chafes.
Materials: Wool, nylon, and elastane.
Inseam: 5 inches.
Style: Boxer brief.
BEST COMPRESSION SHORTS FOR WORKING OUT
Wolaco North Moore Short
Even the most discerning connoisseurs of compression shorts can get behind Wolaco’s North Moore short. No detail here is overlooked—from the sweat-proof pockets that can stow a cell phone throughout your toughest workouts to the just-right moderate compression for both performance and comfort to the anti-pilling material that lasts through many, many washes. The six-inch inseam style is a solid option that could be worn as underwear, and the nine-inch inseam style offers that much more coverage so even the most modest could wear these as shorts all on their own.
Materials: Polyester and spandex.
Inseam: 6 to 9 inches.
Style: Compression short.
BEST POUCH UNDERWEAR FOR WORKING OUT
BN3TH Pro Boxer Briefs
Don’t knock it until you’ve tried it—pouch underwear is the way to go if you’re looking for impregnable support that hugs your privates. BN3TH in particular makes a proprietary pouch shape that prevents chafing. Throw in some flatlock seams, a no-roll waistband, and no-stink technology, and you’ve got a solid pair of pouch boxer briefs that will serve you well in your next workout.
Materials: Polyester and spandex.
Inseam: 6.5 inches.
Style: Boxer brief.
MOST BREATHABLE UNDERWEAR FOR WORKING OUT

BEST MOISTURE-WICKING UNDERWEAR FOR WORKING OUT

BEST SUSTAINABLE UNDERWEAR FOR WORKING OUT
Bombas Active Flyless Boxer Briefs
There’s a lot to love about these seamless boxer briefs from Bombas. Yes, they’re insanely comfortable, they have a secure leg opening that won’t ride up, and have all the anti-stink, moisture-wicking properties we expect from underwear geared toward work outs. But the real clincher is that this pair is made from 86 percent recycled polyester, which significantly reduces their carbon footprint.
Materials: Recycled polyester and elastane.
Inseam: 5 inches.
Style: Boxer brief.
MOST SUPPORTIVE UNDERWEAR FOR WORKING OUT
Under Armour UA Tech Boxerjock
Workout underwear isn’t just about the no-stink and moisture-wicking properties—though those are important factors to consider. The right pair of undies should keep your, erm, goods secure as you run, squat, and high-kick your way through your workout. The fit on these Under Armour “Boxerjocks” is fantastic, and they come in a variety of inseam lengths depending on your personal preference. They’re stretchy and secure without being too tight. And even at the shortest three-inch length, you can rest assured that nothing is going to chafe, bunch, or come peeking out when doing the deepest lunges.
Materials: Polyester and elastane.
Inseam: From 3 to 9 inches.
Style: Boxer brief.
BEST WOOL UNDERWEAR FOR WORKING OUT
Smartwool Intraknit Boxer Briefs
We say it time and again: Few fibers can compete with the natural moisture-wicking and anti-microbial properties of merino. Don’t make the mistake of thinking these are some woolen undies that will itch and stifle on your next workout—the opposite is true. They’re lightweight, soft, and smooth, and the fabric is reinforced with lyocell (for added softness) and synthetics fibers, which means it’ll stay snug all day long.
Materials: Merino, lyocell, polyester, elastane, and nylon.
Inseam: 6 inches.
Style: Boxer brief.
SOFTEST UNDERWEAR FOR WORKING OUT
Tommy John Second Skin Trunk
Comfort is everything, especially when you’re going hard in the gym. These Tommy John “Second Skin” trunks fit and feel exactly as their name implies—and they stay in place without bunching or chafing. Not only do they come in a range of colors and prints if you’re the type of guy who appreciates a little flair on his underthings, but they are also incredibly soft, so you just might want to wear them even when you’re not working out.
Materials: Modal and spandex.
Inseam: 4 inches.
Style: Trunk.
BEST SEAMLESS UNDERWEAR FOR WORKING OUT
Uniqlo AIRism Ultra Seamless Boxer Briefs
Seams can be problematic for your workouts; they typically cause chafing and discomfort. That’s not the case with this pair, however, which features a unique, completely seamless design. The fabric is smooth and stretchy, and it has that “barely there” feel that so many people crave from workout underwear.
Materials: Nylon and spandex.
Inseam: 3 inches.
Style: Boxer brief.
BEST BRIEFS FOR WORKING OUT
Lululemon Always In Motion Brief
High-cut briefs offer an increased range of motion and basically make bunching a thing of the past. If you’re looking for a brief for workouts, however, skip the old-school cotton ones and try something like this style from Lululemon. They’re made from a super soft modal fabric that dries in an instant.
Materials: Modal and elastane.
Inseam: None.
Style: Brief.
BEST JOCKSTRAP FOR WORKING OUT
Calvin Klein Athletic Active Jockstrap
Find a well-fitting jockstrap and you may discover that they won’t only keep you secure during your workouts; they’re also comfortable enough for all-day wear. Keep things classic and stick to something from Calvin Klein. This one blends the softness of cotton with the stretch and fit of elastane and is finished with miDori moisture-wicking finish to keep everything dry.
Materials: Cotton and elastane with a miDori bio-wicking finish.
Inseam: None.
Style: Jockstrap.
