1. Best Value: Uniqlo

^{Back to top ^}

First up on the list of best undershirts for men is UNIQLO. This hugely popular fashion retailer is known globally for their affordable quality and minimal basics.

It’s become one of my favorite places to shop. And being a shorter guy (~5’6″), their clothes fit exceptionally well. They also offer in-store hemming for their jeans and chinos which is a highly convenient service that no other major retailers offer.

Best of all, Uniqlo HeatTech undershirts come in a variety of versatile colors and sizes, crewnecks and v-necks (just like their popular Supima cotton t-shirts).

Uniqlo HeatTech Short-Sleeve T-Shirt

I’ve had my Uniqlo HeatTech undershirts for several years now. They’ve been through countless wash and dry cycles, although I started to hang dry them more recently so that they last longer. And they do shrink slightly, so be aware of that.

I wear them year-round, as a base layer under my thicker shirts and sweaters in the winter, and in warmer weather, under a lightweight vest for example.

It isn’t the mountains ahead to climb that wear you out; it’s the pebble in your shoe. 🍁🍃🍂

A post shared by khoi n.✏️ | Gentleman Within (@lifeaskhoi) on Oct 25, 2015 at 11:34am PDT

The shirts fit me like a muscle fit which is the way an undershirt is meant to fit. It’s snug all over from the chest, through the body and around my biceps. It’s actually a little bit too tight and the sleeves are a bit short for my liking. I might be able to get away with wearing a size small as opposed to XS. 

It’s got just the right amount of elasticity and is easy to tuck into my pants or boxer briefs. Additionally, it has a pretty trim collar around the neck for a sleeker appearance.

Shop HeatTech Short Sleeve

A problem area with the shirt is that one of the crew neck collars has lost its shape a bit. Bacon collar aside, I’ve gotta say that they’ve held up very well over the course of the past few years.

It looks like they’ve since updated the shirt design since I purchased mine. Instead of a tag on the collar, the undershirts are now tag-less and it looks like shirts are now longer to make for an easier tuck.

Uniqlo HeatTech Long-Sleeve T-Shirt

Uniqlo’s HeatTech long sleeve shirts are essentially the same as their short sleeve shirts, except with the long sleeves which make them the perfect undergarment for colder weather. I particularly like to wear them as a base layer while snowboarding or other winter activities.

It’s lightweight enough to allow for full mobility and still does a good job of insulating to keep my core warm up on the mountain. They also carry an ultra warm version that’s touted as 1.5 times warmer than regular HEATTECH and an ultra warm turtleneck long sleeve that’s 2.5 times warmer than HEATTECH.

Just like my short sleeve shirts, I’ve had my long sleeve undershirts from Uniqlo for many years now. They’ve been through countless wash and dry cycles and are holding up well.

The long sleeve undershirts fit just like the short sleeve shirts too. And the sleeves are slightly shorter than full-length sleeves so that they stay hidden under your outer layers.

Finally, the v-neck HeatTech shirts have a deeper “v” cut that is intended to keep the shirt hidden under dress shirts. And just like the short sleeve shirts the collar is trimmer than most undershirts I’ve worn.

• Sizes: XS-XXXL
• Material: 34% Rayon, 33% Polyester, 28% Acrylic, 5% Spandex

The Bottom Line:

UNIQLO offers the most affordable undershirt options out of every brand on this list coming in at under $15, making it the best value undershirt you can buy.

2. Best T-Shirt Alternative: Twillory

^{Back to top ^}

Twillory is known for their performance, non-iron and untuck(able) dress shirts. But what you didn’t know was that they also carry underwear and undershirts, aptly named underTwills.

Twillory prides itself in timeless craftsmanship, timely styles and tailored fit at affordable prices. 

» Related: Check out this Twillory Performance Pants Review.

Twillory Performance Undershirt

Twillory’s performance undershirts come in a crew neck or v-neck variety in white or a tan (tonal) color. I personally prefer the tonal undershirt as it blends with my skin tone as opposed to the contrast of a white, though white is still a perfectly fine option. The v-necks are very similar to that of David Archy bamboo undershirts.

On the back of the shirt, under the neck is a silver reflective Twillory “T” logo printed which is a welcome design detail. Their performance shirts are made with a sweat-wicking, cooling technology and sleeves that don’t ride up into my armpits. And it’s got a length that’s appropriate to wear untucked or tucked in.

Out of all the undershirts in this roundup, Twillory’s performance undershirt feels and fits the most like a t-shirt. The fabric feels thicker and more substantial. It could easily be worn casually as a standalone shirt during a light run or workout or as a moisture wicking base layer, worn under an oxford shirt, talk about versatility.

Although Twillory’s performance undershirt might be too loose fitting for some to wear as an undershirt, I still think that it’s a good fitting undershirt option for some men.

At $24 a shirt, Twillory is in the middle-tier price point for undershirts in this roundup. Furthermore, you can bundle and save at 2 for $36 or 4+ for $14.50 each. That’s a tremendous value.

Buy Twillory Undershirts

Twillory Performance Undershirt Details:

• Sizes: S-XXL
• Material: 47% Rayon, 47% Cotton, 5% Spandex
• Made In: China or Vietnam
• Colorways: 2
• Price: $24 or 2 for $36 and 4+ for $14.50

Twillory Performance Tee

The Twillory performance tee wears like a workout shirt that you can exercise in, but it looks like a basic tee and so it’s appropriate to wear for the gym, lounging at home, or when you’re out and about.

There is a subtle sheen to the fabric and stretch like that of an undershirt. Perhaps the best thing about this shirt, besides the near perfect fit, is how comfortable and breathable it is. It’s definitely a shirt I’ll be wearing plenty of in the warmer spring and hotter summer months.

If you’re wondering whether or not there’s any shrinkage, the performance tee does not shrink in the wash or dryer, and so don’t expect for it to shrink to a more appropriate size after a wash/dry cycle.

Overall, there’s not much to this shirt. It’s super basic and does exactly as its name suggests — it’s meant for performance, keeping you casual, cool and comfortable. 

Twillory Performance Tees

Twillory Performance Tee Details:

• Sizes: S-XXL
• Material: 100% Performance Poly Stretch Fabric
• Made In: Thailand
• Colorways: 6
• Price: $44

The Bottom Line:

Both the Twillory performance undershirt and performance tee are the best options that you can wear casually and comfortably as a t-shirt, and have all the beneficial properties you’d want in an undershirt as well.

3. Best Unique Fabric: Mr. Davis

^{Back to top ^}

This is a brand that likes to sweat the little details by investing in quality fabrics that are made to last. They are small and nimble with a dedicated customer support team that you can email or chat with anytime.

Mr. Davis touts itself as having the World’s Best Undershirt. That’s a bold statement and I think the other brands in this roundup would have something to say about that. Audacious declaration aside, their undershirts do come highly reviewed both on their website and Amazon.

Premium Tailored V-Neck Undershirt 

The Mr. Davis undershirts come in a tailored or traditional fit which makes it well-fitting for a multitude of body types. I personally prefer the tailored cut as it follows the shape of my body and provides a more streamlined fit.

What’s great about Mr. Davis is that they offer a tan option, while the raglan sleeves accentuates the shoulders. It is thicker though, with a noticeably wider neckline trim. It also has the regular crewneck or Tailored V-Neck Undershirt options and 4 colors of white, grey, black or tonal.

Mr. Davis is the only undershirt brand on this list that’s made primarily with bamboo viscose (94%), which gives it a soft/silky feeling and appearance, along with keeping me really cool. Additionally the 6% spandex provides ample stretch. 

A problem area I noticed with the shirt and I’m not sure if it’s simply a minor defect, but the fabric at the back collar of the shirt behind my neck tends to bunch up over time. I only noticed this occured after I put the shirt through a wash and dry cycle. The shirt didn’t shrink, though.

Comfort Fit Premium Tailored Cut Undershirt Details:

• Sizes: XS-XXL
• Material: 96% bamboo viscose, 4% spandex
• Made In: China
• Colorways: 4
• Price: $25 or $69 for 3-pack

Shop Mr. Davis Undershirts

The Bottom Line:

Whether Mr. Davis undershirts are the best in the world, that’s up for debate, but these bamboo constructed shirts are some of the coolest and most comfortable on the market. My recommendation is the tonal color, it’s the best option for most skin tones.

4. Best Performance: Ministry of Supply

^{Back to top ^}

Ministry of Supply specializes in “workleisure” wear, which is essentially smart casual style, with a focus on professional yet comfortable clothing. You could say that it’s athleisure for work wear.

Ministry of Supply’s Active Tee is true to its name, you’ll want to wear this shirt for when you are most active. It’s currently among Ministry of Supply’s best-selling pieces.

Responsive Tee

The basic tee is one of the core items that every man should have at least a  handful of in his closet. And so it’s no surprise that the Responsive Tee is one of Ministry of Supply’s best sellers. *It’s currently no longer in stock, but the Composite Merino Raglan Tee is a solid alternative.

If you like more of a muscle fit with fabric closer fitting to your body, then Responsive Tee is for you. They carry a crewneck and v-neck version, the v-neck being ideal to wear as an undershirt to your dress shirts.

Coming in 2 essential t-shirt colors of black and white, the Responsive Tee is an ideal undershirt and can still be worn on its own as a basic tee so long as you size up.

Believe it or not, the Ministry of Supply Responsive Tee is made with coffee-infused recycled polyester yarn to absorb odor. The shirt is meant to be ‘responsive’ to your body’s movements and dry twice as fast as cotton.

The fabric feels super soft to the touch and is just as lightweight as some of my other undershirts. It certainly has a premium feel and a slight shine under certain lighting. I tested it and there’s no need to worry about bacon collar or shrinkage after washing either.

The recycled polyester is made to pull excess heat and moisture, transferring it away from your body to keep you dry when those workouts are getting intense or if you just tend to sweat a lot.

The shirt also has considerable stretch while still retaining its shape. And so you don’t have to worry about the Responsive Tee getting warped in a wonky wash cycle. I’ve had this happen to some of my other shirts before and the shirt is never quite the same afterwards.

In terms of fit, the Responsive Tee is quite snug on my body — around the chest, biceps and midsection. It definitely wears more like an undershirt than a t-shirt. Size small would likely make for a much better fitting tee.

The sleeves hug my bicep nicely and are the appropriate length (albeit a tiny bit short), slightly above mid-bicep. The shirt’s shoulder area isn’t bunching up and extends right out to my shoulder bone. And as for the shirt’s length, it’s just right — short enough to be worn untucked and just long enough to be tucked in as an undershirt should be.

Ministry of Supply Responsive Shirt Details:

• Sizes: XS-XXL
• Material: 100% coffee-infused recycled polyester
• Made In: China
• Colorways: 2

Shop The Composite Tee

The Bottom Line:

Overall the Responsive Tee is made for performance, is slim fitting and looks great on guys with a sturdier build. Again, size up if you want to rock this shirt as a tee.

5. Best Drape: SilkCut Underwear

^{Back to top ^}

SilkCut Underwear (formerly Tani USA) is a US based direct-to-consumer company whose goal is to make the world’s best underwear. Through their patented fabrics and inventive knitting techniques.

SilkCut Underwear is out to set the standard of the world’s best underwear, period. They do this through innovation in every aspect of their garments from patented fabrics, made with high durability, easy washability in mind to ensure a longer lasting garment.

SilkCut Underwear Crew Undershirt

Similar to Twillory, the SilkCut crew undershirt can be worn both as a base layer and a basic tee. I’d say that their undershirt has the most flowy drape and some of the nicest feeling fabric I’ve ever felt on a shirt. It’s just got a super soft and buttery smooth texture and feeling.

I got size medium which is too long to wear as a t-shirt, but makes for an excellent undershirt option. It’s form-fitting with naturally moisture wicking fabric. The Micro Modal Air fabric is softer and thinner than silk, and it’s less see through than Ribbed Tee’s EVO TENCEL shirt (which is highlighted later on).

Additionally, SilkCut Underwear fabrics can keep you warm when it’s cool and cool when it’s warm—just the type of versatility you want from an undergarment or t-shirt. I also have a set of their SilkCut Thermal Underwear and it’s especially true of the long sleeve thermals that I’ve been wearing to bed as pajamas during the cooler months.

I want to mention that it’s not the best undershirt to wear if you want it to keep hidden. The crewneck is cut close around the neck while the v-neck isn’t deep enough to remain hidden under some unbuttoned dress shirt. And finally, the shirt didn’t shrink through a wash and dry cycle.

SilkCut Underwear Crewneck T-Shirt Details:

• Sizes: S-XXL
• Material: 94% Micro Modal Air, 6% elastane
• Made In: USA
• Colorways: 4
• Price: $59

See Tani Silk Cut Shirts

The Bottom Line:

When it comes to how it feels and fits, SilkCut Underwear is one of my favorites. And the Micro Modal AIR technology is something you’ll want to feel for yourself.

6. Best Sweat Protection: Thompson Tee

^{Back to top ^}

As of 2016, it’s estimated that 15.3 million people or 4.8% of the US population suffer from hyperhidrosis, which is abnormally excessive sweating that’s not necessarily related to heat or exercise. This type of heavy sweating often causes social anxiety or embarrassment.

The founders of Thompson Tee relate to the struggles of those with hyperhidrosis and so they spent more than 10 years developing a lightweight, breathable, comfortable underarm barrier that absorbs sweat and withstands tough stains.

Thompson Tee Sweat Proof Undershirt

While technically an undershirt, the Thompson Tee might fit you well as a t-shirt depending on your build. For me, the shirt was huge out of the packaging, but I was surprised that it shrunk down considerably after a single wash and high-heat, dry cycle. 

Thompson Tee is hands down the best undershirt for sweat because it comes with a proprietary design that stops sweat from showing through your underarms, which is a lifesaver for those who suffer from hyperhidrosis or just tend to sweat a lot in general.

I have to be honest, it feels a little weird having that extra padding under your arms, and while it’s not uncomfortable, but does take some getting used to. You can definitely feel the protection, though.

In terms of the Thompson Tee as an undershirt, it’s a bit too heavy weight of fabric for an undershirt IMO, especially with the sweat panels under the arms, and so that’s why I recommend it as a t-shirt. YMMV depending on your build. For reference, I’m 5’6″, 135 lbs.

Thompson Tee Sweat Proof Crewneck Details:

• Sizes: XS-XXXL
• Material: 100% Premium Combed Cotton
• Made In: USA
• Colorways: 7
• Price: $33.99

Shop Thompson Tee Undershirt

The Bottom Line:

If you want a t-shirt or undershirt with sweat proof technology that’s made in the USA with quality fabrics, Thompson Tee is the perfect shirt for you.

7. Best Color Option: Organic Basics

^{Back to top ^}

Organic Basics (recently underwent a change in management, but is back up) knows that the fashion industry is run amuck with seasonal trends and disposable clothing, and so they set out to put sustainable thinking at the core of everything that they do. From the fabrics to the factories that they choose to work with, it’s all about being mindful of the environment.

As its brand name suggests Organic Basics makes clothing ethically made, “Vegan Approved”, with GOTS certified organic cotton. It’s quality basics, meant to last, and sourced the right way.

Organic Basics Soft Touch Tencel Lite Tee

Similar to Twillory and SilkCut Underwear (Tani), the Organic Basics Soft Touch TENCEL Lite Tee (alternative) is designed as a base layer that wears well as a plain t-shirt.

The Organic Basics TENCEL Tee is a soft undershirt that’s made with eco-friendly wood pulp fiber called TENCEL which is softer and lighter than cotton because of the smaller fibers. It feels similar to silk, spandex or bamboo fabric.

In terms of the shirt’s design, there’s a slight v-neck and the shirt is fitted throughout from the chest down to the arms and waist. I personally feel that the shirt fits my body quite nicely.

The Organic Basics undershirt comes in black, white and navy colors. There’s also a dark green (olive) that I have a preference towards, and is different from the colors offered by other brands.

When it comes to casual basics, premium products usually come with a premium prices, and Organic Basics TENCEL Tee comes in at $65 (now for $28), which puts it at a competitive price in this roundup. It used to be a lot to swallow for a short sleeve shirt, but generally TENCEL products tend to be more expensive than cotton. And now that it’s under $30, it’s a sure steal.

Organic Basics Soft Touch T-Shirt Details:

• Sizes: S-XXL
• Material: 95% lyocell TENCEL, 5% elastane
• Made In: Portugal
• Colorways: 4
• Price: $32

Shop The TENCEL Lite Tee

The Bottom Line:

Organic Basics is transparent about where their products are sourced from, which is admirable in a world where many brands choose to omit these facts. It’s a premium product at a now affordable price. If you’re looking for high quality basics, Organic Basics is definitely worth a look.

8. Best Design: Manual Outfitters

^{Back to top ^}

A note: Manual Outfitters’ The Baselayer undershirt is currently on Final Sale without any indication of when they’ll be back. A darn shame!

This direct-to-consumer brand has a goal to replace the clutter and waste in every man’s wardrobe with a small collection of well-crafted, high performance basics. They’re committed to creating apparel that’s worthy of a spot in your collection.

Manual Outfitters (alternative) is all about creating products that outperform, outlasts and out-comforts anything you’ve worn before, all the while being mindful of sustainability. It’s a worthy cause worth getting behind, but how nice are their undershirts?

Manual Outfitters The Baselayer

Manual Outfitters ‘The Baselayer’ comes in a performance blend of fabrics from eucalyptus origin lyocell, cotton and elastane. It’s made with a proprietary seam design that helps break tension under your arms, providing free range of motion. It’s more so along the lines of performance and active gear rather than a plain undershirt.

When you wear the shirt, you can feel the difference from ordinary tees and undershirts. The seams under the arms provide a performance tech feel. It’s a shirt you’ll want to workout in.

I like the way the shirt fits and is perfect to be worn under your favorite button downs or standalone as a basic tee, although it’s better suited as a baselayer as its name suggests.

It’s got a refined, clean fit. What’s cool is that they have a less medium and more medium size which is ideal for those who may be in-between small and medium or between a medium and a large. It comes in two colors of clean white or black. And the shirt may shrink slightly in a wash and dry cycle.

Manual Outfitters Baselayer V-Neck Details:

• Sizes: S-XXL
• Material: 62% lyocell, 30% cotton, 8% elastane
• Cut & Sewn In: Massachusetts
• Made In: Portugal
• Colorways: 2
• Price: $44

See Gildan Undershirt

The Bottom Line:

Manual Outfitters ‘The Baselayer’ has an exceptional design that’s unlike any of the shirts in this roundup. You’ll feel the difference the second that you put it on. If you like to workout and want to look good while you’re at it, The Baselayer is a great option.

9. Best No-Show: RibbedTee

^{Back to top ^}

A note: Ribbed Tee is currently no longer in stock with no indication of when they’ll be back. A darn shame!

RibbedTee is a direct-to-consumer brand founded by Mike and Kim Schwarz in 2008. Their goal was to create the world’s most comfortable and best fitting undershirts, educating along the way, while helping people be more confident.

While RibbedTee (alternative) might not be a massive, well known brand—in the world of undershirts—their reputation, dedication to quality and customer service is top tier.

They source all products locally in the USA from their Los Angeles-based manufacturing partners, the same ones they started with in 2008. Furthermore, RibbedTee isn’t just about selling undershirts, but in educating their customers through their blog.

RibbedTee EVO TENCEL Deep V-Neck Undershirt

RibbedTee’s EVO TENCEL undershirt is made with 94% tencel fabric which is ultra soft and an excellent cooling material. These shirts are a perfect balance of fit and function. It has a similar style and design to the Mr. Davis Premium Tailored Undershirt in that there’s a tan option as well as the raglan sleeves.

Their undershirts are made with a lightweight and breathable material, it’s also rather sheer and even a little bit see through, which is good or bad depending on your preference. It’s not quite as silky feeling as Organic Basics’ TENCEL Lite Tee. However, it’s so light that sometimes it feels like you’re wearing nothing at all which is a huge benefit in my eyes. 

There’s several reasons why this undershirt is the best no-show option in this roundup:

1. The lightweight fabric and longer shirt length makes it optimal for tucking in and staying tucked in
2. The deep v-neck and thin material ensures that it always stays hidden under your top layers
3. The tan color option helps keep it more discreet under white dress shirts
4. The neckline is more trim than any other undershirt I’ve worn
5. The raglan sleeve design provides a more seamless fit

RibbedTee undershirts come in a crew neck or deep v-neck, and in a white, light grey or tan color option. They don’t carry anything smaller than S or larger than XL which could be unfortunate for some, but there’s so much stretch to these shirts that most men are likely covered. In my experience the size small fits me well—I’m 5’6″, 135 lbs. for reference. And finally, RibbedTee undershirts do not shrink in a wash and dry cycle.

See David Archy Undershirts

RibbedTee EVO TENCEL Deep V-Neck Shirt Details:

• Sizes: S-XL
• Material: 94% TENCEL, 6% Spandex
• Made In: USA
• Colorways: 3
• Price: $32

The Bottom Line:

RibbedTee’s undershirts are not only the ‘best no-show’ in this roundup, but they’re also some of the most comfortable and high-quality on the market. I’ve worn their EVO TENCEL undershirt for years now and recommend them highly.

10. Best Budget Option: Amazon Essentials

^{Back to top ^}

Amazon Essentials is a clothing line of basic wear for men, women, kids and baby. There’s also additional options for family, big and tall and athleisurewear.

On the men’s side of things, Amazon Essentials offers everything from shirts, polos, flannels, bottoms, shorts, loungewear, sleepwear, swimwear, underwear and socks.

GW has found that the Amazon Essentials 6-pack v-neck undershirts to be the best budget option among all the undershirts in this roundup. They also offer a 6-pack crew neck undershirt as well in black and white colors.

Amazon Essentials 6-Pack V-Neck Undershirts

The Amazon Essentials undershirts are tagless and are made with a medium thick fabric, leaning towards the lighter side of the fabric thickness spectrum according to a highly upvoted answer in the Q&A section. 

Furthermore, the v-neck undershirts do not show under a dress shirt, with the top 2 buttons unbuttoned which passes the no-show test.

According to Top Reviews on Amazon:

• These shirts run on the small side and are shorter than he likes, so he suggests ordering one size up. They do shrink a little (not much if you hang dry) so it doesn’t hurt to order up if you’re afraid these might be tight.
• Better than Hanes, FOTL, and Banana Republic undershirts.
• The tee shirts are really great, especially for the price — sized well, good thickness, solid seams, etc. The only problem is the label. Instead of indelible ink, it appears to be thermally applied plastic type. By the 2nd laundering, the writing starts coming loose.
• I bought Hanes, Jos A Bank, Kirkland, and a few other brands. I rank Kirkland #1, JAB #2, and Amazon Essentials #3 if judging just quality of stitch and softness. Overall best value however goes to Amazon Essentials.

These undershirts look to be a trim fit, hugging the body, but can wear like a t-shirt if you decide to size up. It comes in two colors of black and white and sizes XS-XXL.

See Amazon Essentials

Amazon Essentials 6-Pack V-Neck Undershirt Details:

• Sizes: XS-XXL
• Material: 100% Cotton
• Made In: Overseas
• Colorways: 2
• Price: $23 for a pack of 6

The Bottom Line:

The Amazon Essentials undershirt is a great value considering you get 6 shirts for a more affordable price than many of the other undershirts. The quality likely isn’t up to snuff, but if you’re someone who goes through t-shirts and undershirts like no one’s business, the Amazon Essentials undershirts are a great option.

11. Best Variety: Tommy John

^{Back to top ^}

Tommy John is a husband and wife team, founded by Tom and Erin. They had no background in clothing design or manufacturing, but set out to reinvent men’s undergarments anyway.

They both left their careers, cashed out their 401Ks and had the goal of creating more tailored, well-fitting and fashionable undergarments, and that’s how their patented Stay-Tucked undershirt and the Tommy John brand was born.

Tommy John Second Skin Stay-Tucked Undershirt

Tommy John’s undershirts as the name suggests wear like a second skin and is long enough to tuck in and stay tucked all day long. 

These shirts are designed for daily wear and are advertised as “silky-soft” and “non-pilling” in addition to having a lay-flat, stretch rib Memory Collar that eliminates “bacon neck” which is a common problem with many cheap t-shirts and undergarments.

According to Reviews on Their Website:

• Amazing how it stays tucked in, but the sleeves seem too short and ride up on me.
• It’s much thinner than in the pics, almost transparent on your skin.
• These shirts just don’t fit right. I purchased med and large. Both squeeze you in areas that just don’t feel right. I may try x large but as of now, not impressed with these shirts at all.
• I like the cool cotton material and found it a little more comfortable than the second skin, but I enjoyed both. 

What’s great about Tommy John undershirts, whether you choose the Cool Cotton or Second Skin option, they both come in high v-neck, deep v-neck and crew neck varieties. It’s always good to have options.
