We researched dozens of undershirts—ranging from inexpensive basics to those from luxury brands—and found 15 that stood out from the crowd. These undershirts will keep you cool and looking put together, no matter what your day or wardrobe looks like.
Sizes: S to XXL | Colors: Bright White | Fit: Slim| Material: Polyamide, polyester and elastane
What’s notable: Technical features keep you cool and dry.
What could be better: At $103 for a pack of three, these undershirts are on the expensive side.
These lightweight undershirts are “ladder stitched” for breathability, and the moisture-wicking, odor-controlling fabric keeps you cool and dry. The extra length prevents the shirts from becoming untucked, and the slim fit and four-way stretch make them easy to layer under dress shirts.
What the reviews say: One reviewer who buys these undershirts for her son says: “These undershirts are soft and well-made. (The) texture is incredible. They’re long enough for my 6-foot 2-inches son to easily tuck into dress pants.” Another reviewer sums up these shirts by saying: “I love the fit and the feel—soft and not too heavy or light.”

Hanes Moisture-Wicking Crewneck Performance Undershirt (5 Pack)
Sizes: S to XXL | Colors: White | Fit: Regular | Material: Rayon and polyester
What’s notable: The excellent price ($5 per shirt!) and sweat-wicking technology make this five-pack a bargain.
What could be better: These shirts are on the thin side.
Hanes is practically synonymous with undershirts, and this bundle offers excellent value. The shirts have built-in “FreshIQ” odor protection technology to keep you smelling fresh and “X-Temp” double-dry technology to wick away moisture, ensuring you won’t get sweat stains even on hot days—and the shirts are soft and breathable, too.
What the reviews say: Customers like the look and feel of these shirts, although some comment that they are too thin. The biggest complaint is about the smell when you open the package. “It’s a very strong chemical smell,” says one reviewer.
Sizes: XS to XXL | Colors: 9, including White | Fit: Classic | Material: Pima cotton, nylon, Lyocell and Lycra
What could be better: Since it’s a regular T-shirt, it won’t feel as thin as a traditional undershirt.
This technically isn’t an undershirt. But because it’s made from soft Pima cotton with a hint of Lycra for stretch, it can be worn as a base layer as well as a t-shirt. The soft and comfortable material is abrasion-resistant and quick-drying in case you work up a sweat, and it’s treated with No-Stink Zinc technology to keep you smelling fresh. The nylon and Lycra help the shirt retain its shape after washing.
What the reviews say: “This is a very comfortable shirt. Looks good (and I) can dress it up or down,” says one reviewer. Another says, “I love the light feel and the wicking (that) the fabric provides.” And finally, “This shirt fits perfectly and is so comfy.”
Sizes: S to XXL | Colors: Black, White, Grey Heather | Fit: Regular | Material: Cotton
What’s notable: These shirts are lightweight, breathable and cozy.
What could be better: Made from 100% cotton, they are prone to shrinking.
Calvin Klein’s undershirts are lightweight enough for everyday wear under your dress shirts, but they’re still substantial enough to be worn alone with jeans or shorts—or even a suit. The 100% cotton material is soft and naturally breathable, and the fit is on the relaxed side.
What the reviews say: The reviews for these Calvin Klein undershirts are very positive. The biggest gripe is about sizing after the shirts go through the wash. As one reviewer puts it, “A medium fits great, but after one wash, they shrink and become too small.”
Sizes: S to XL| Colors: White | Fit: Slim | Material: Pima cotton and spandex
What’s notable: The deep V-neck doesn’t show under shirts and the material is sweat-wicking.
What could be better: Certain sizes are hard to find.
One common complaint about undershirts is that the necks are too high, and can be seen under your shirts. The Tommy John Deep V-neck undershirts are undetectable under your clothes, and guys love the soft feel (thanks to the Pima cotton), snug (but not tight) fit, and breathable, moisture-wicking material. The shirts are a little on the longer side, but they don’t look or feel bulky when tucked in.
What the review say: “This product stretched perfectly and stayed tucked in as advertised. I always get hot in my other undershirts, but this thing felt like I wasn’t wearing anything all day. The fabric is the lightest, softest, and coolest I’ve ever tried,” says one reviewer. Another customer praised the fit and added, “this is one of the few brands where you can wear it under a shirt without a tie and it will not show.”
Sizes: S to 3X | Colors: Black and White | Fit: Relaxed| Material: Cotton
What’s notable: This undershirt is durable and sweat-wicking.
What could be better: Because it’s a 100% cotton, it’s more likely to wrinkle and shrink.
This is a basic, inexpensive undershirt with some surprising perks. Made from 100% American-grown cotton, it features StayCool + technology to wick away sweat and StayNew technology to keep the shirt looking new and fresh wash after wash. The neck also remains flat (no stretching) and this shirt is tag-free to prevent irritation.
What the reviews say: “I’ve tried a dozen black undershirt brands. Some brands are too thin, some are too thick. Some have a weird collar. Some brands are cut weird. Finally: these are perfect,” says one reviewer. Customers are particular about the neck area of their undershirts, and this one passes muster. “The most important thing to me is that the neck (on this shirt) stays tight. (It) doesn’t stretch out,” says one shopper.
Sizes: XS to XXXXL | Colors: Bright White, Black Jack and Medium Grey Heather| Fit: Slightly fitted | Material: Cotton
What’s notable: The shirts are tag-free and have Go-Dry moisture-wicking technology—and the price is right.
What could be better: These undershirts are prone to wrinkling and may shrink.
For a little more than $5 a pop you get a basic but well-made 100% cotton undershirt that has built-in Go-Dry moisture-wicking technology to keep you feeling dry all day, and Old Navy ditched the tag to prevent skin irritation. Plus, the shirts feels soft and has a nice slightly tailored cut.
What the review say: Reviewers love the feel of this shirt. “I love how soft it is and (it) has no itchy tag which (is) usually uncomfortable for people with sensitive/eczema prone skin,” says a reviewer. A different customer describes the shirt as “light and comfortable—size is great.”
Sizes: S to XL | Colors: White | Fit: Slim | Material: Mercerized cotton and elastane
What’s notable: The longer length ensures it stays neatly tucked in.
What could be better: This undershirt is expensive.
Made in Portugal of mercerized cotton (mercerization is a treatment that makes cotton brighter and increases luster) with a touch of elastane, this undershirt is designed for a stretchy, slim fit, and the longer length prevents it from riding up during the day. The brand advises that the undershirt runs small, so you may want to consider sizing up. However, because the largest size available is an XL, doing so may be an issue for bigger guys.
What the reviews say: One reviewer describes the shirt as feeling “like silk” but warns that it “requires some TLC when you wash it.”
Sizes: XS to XXXL | Colors: White and Black | Fit: Regular | Material: Cotton
What’s notable: The material is incredibly soft and lightweight.
What could be better: At $65, this undershirt is on the expensive side.
This British company is known for its luxuriously soft and flattering t-shirts for both men and women, and their undershirts are no exception. This cotton pick is made from long-staple cotton jersey, which has longer fibers than traditional cotton types and is often used for high-end bedding because it’s soft and lightweight. This material is also more breathable and better at absorbing moisture than synthetics, making it an ideal choice for undershirts.

Polo Ralph Lauren Classic Fit V-Neck Undershirt (Pack of 3)
Sizes: S to 4X Tall| Colors: Black, White, Mult-Pack | Fit: Classic | Material: Cotton
What’s notable: The shirts are soft, moisture-wicking and come in tall sizes.
What could be better: If you aren’t a fan of logos, you may not like the pony icon embroidered on the waist (but when the shirt is tucked in, you won’t even see it.)
These V-neck undershirts are made from 100% combed cotton (which basically means that the cotton has been treated to remove short fibers, creating a softer and more luxurious feel), they’re tagless to prevent skin irritation, and they’re breathable and moisture-wicking. The classic, loose fit makes these shirts ideal for layering or sleeping.
What the reviews say: Reviewers are impressed by the weight of the shirts and comment on the length. “(They’re) soft but not too thin. Long enough for tucking into jeans. Really happy with them.” Another describes them as “semi-thick and long.” Some find them unusually long, but not in a bad way. “I love them! Very comfortable and lightweight. A bit long even for an undershirt but still, a very solid buy.”
What’s notable: It’s long enough to stay tucked in, and the flattering cut and slightly heavier fabric allow it to be worn solo too.
What could be better: Those used to really thin tanks may find this one a little heavy.
If you find undershirts too bulky under dress shirts, consider a tank top. This one from Todd Snyder is made in Peru out of a silky combination of cotton, modal (a semi-synthetic fabric derived from beech tree pulp) and spandex. It’s long enough to stay tucked in all day, it has a ribbed design, and at 200 grams in weight, it’s substantial enough to be worn without a shirt over it, too.
What the reviews say: Reviewers are impressed with the tank’s quality and cut. “It’s the highest-quality tank I’ve ever owned and great fit,” says one. “Quality is superb and fit is amazing,” echoes another.
Sizes: XS to 5X | Colors: 2 total, including Chalk and Obsidian | Fit: Slim | Material: Modal and elastane
What’s notable: Inclusive sizing goes up to 5X.
What could be better: These undershirts tend to run a big, and some find the neck to be a little large.
Kim Kardashian’s wildly popular line of underwear and shapewear is known for its size inclusivity and clean, simple designs. These undershirts are super-stretchy for a customized fit that won’t bunch up under slim-fitting dress shirts, and the hefty dose of elastane (16%) prevents these shirts from stretching out or losing their shape after washing.
What the reviews say: “This is great as a base because it’s super lightweight as if you’re literally shirtless,” says one reviewer. Many customers are also fans of the fit: “(It) provided a nice snug fit, which was not tight.” Some reviewers do mention that the neckline is “flimsy” or too big.
Nordstrom
Lands’ End Crewneck Undershirt (3 Pack)
Sizes: Regular is available in S to XXL | Colors: Gray, White, Black and Multi 3-Pack| Fit: Regular| Material: Cotton
What’s notable: The shirts are available in big and tall sizes and the absence of side seams is a nice touch.
What could be better: The short sleeves are a little on the long side, so this shirt is best worn under long-sleeve shirts.
Those with sensitive skin will appreciate this extra-soft combed cotton undershirt, which is made without side seams that can rub against your skin, and the neck seam is taped and smooth. The shirts come in Big, Tall, and Big and Tall sizes to accommodate all body types, and black shade comes in handy when wearing darker dress shirts.
What the reviews say: “The t-shirts fit perfectly,” says a reviewer. Another praises the shirts for their durability but points out that the sleeve length is a little tricky: “My only complaint is that the sleeves “hang out” the end of short sleeve shirts, which tend to be 1.5 inches shorter in the sleeve length, so the t-shirt shows. They are great for long-sleeved dress shirts.”
Amazon
Mr. Davis Comfort Fit Premium Bamboo Viscose Tailored Cut V Neck Undershirt
Sizes: XS to XXL | Colors: 4 including White|Fit: Tailored |Material: Bamboo viscose and spandex
What’s notable: The tailored cut skims the body and helps the shirt stay neatly tucked in, and the shirt is available in colors like Dark Brown and Tone.
What could be better: Bigger guys might find this shirt a little too form-fitting.
Bamboo viscose is a soft material that’s produced by breaking down bamboo and spinning it into thread that is then woven into fabric. Naturally moisture-wicking, it’s an excellent fabric for undershirts and sleepwear. Another benefit to this undershirt is the comfortable and flattering cut: The shirt is narrower at the waist and wider at the hips for a streamlined fit, and the longer length ensures the shirt stays tucked into your pants.
What the reviews say: “It’s incredibly soft and has a tremendous amount of stretch. No worries about this thing coming untucked or looking sloppy under your shirt,” says one reviewer. Another reviewer remarked on the fabric: “The material is very soft and feels cool to touch….it held up fine in the sun on a warm day in May when I had to walk a few blocks with a dress shirt and blazer on.”

What To Consider When Shopping For The Best Undershirts For Men
Since undershirts are worn under your clothes, they don’t tend to have a lot of flashy features. But here are a few important elements to look for:
Material
Above all else, undershirts should feel comfortable, which is why they are are typically made of naturally soft and breathable cotton. But there are different types of cotton. For example, Pima cotton is considered the softest and most luxurious, and shirts made of Pima cotton tend to hold their shape well. Many brands add elastane (also referred to as Lycra or spandex) to cotton, to provide stretch and prevent the shirt from feeling restrictive. Shirts that have moisture-wicking properties, like the Hanes Moisture-wicking Crewneck Performance Undershirt, are sometimes made of polyester, which is very durable and washes well, and newer fabrics like Bamboo viscose are also becoming common for undershirts (our top pick is the Mr. Davis Comfort Fit Premium Tailored Cut V Neck Undershirt).
Fit
Since an undershirt should skim your body and is intended to stay neatly tucked into your pants, a slim fit is usually your best bet. Just make sure the shirt doesn’t feel too snug or tight. Classic and regular fits can work too, but anything loose will feel bulky under your clothes.
Color
Of course, undershirts are usually white. White is a safe choice since it won’t show through whatever shirt you’re wearing over it. But in recent years, more men are starting to wear black and gray undershirts as well, which tend to look more modern (and less like the kind your grandfather used to wear). Dark undershirts can be worn under darker colored dress shirts and they are a good choice for layering under V-neck sweaters and polos. They can also we worn solo, like a regular t-shirt.
Technical Features
Undershirts are meant to be basic, so you don’t need a ton of tech elements built into the design. But odor protection and moisture-wicking properties can be very helpful in warm weather, or when you’re wearing a stuffy dress shirt for hours on end. Our top pick, the Mack Weldon AirKnit Crew Neck Undershirt, has both of these features.
Frequently Asked Questions (FAQs)
What Is The Best Quality Men’s Undershirt?
What Is The Best Material For Undershirts
Since an undershirt sits against your skin for several hours every day, natural fibers like cotton tend to be popular. However, newer materials like bamboo viscose and modal (which is a semi-synthetic fabric made from beech tree pulp that feels smooth and silky) are also good options that won’t irritate your skin. Polyester blends are durable and often offer sweat-wicking properties, which is key for undershirts.
Do Guys Wear Undershirts Anymore?
Yes, although wearing an undershirt is not quite as common as it was a decade ago, when most men wore suits and dress shirts to work five days a week and needed a soft barrier between their skin and their business attire. But when you do find yourself needing to wear a dress shirt—whether to work, to dinner or to a formal occasion like a wedding—an undershirt helps absorb sweat and protect your clothes from staining.
