• Crew neckline

Who is it Best for? 

If you prefer sleeveless undershirts, these are for you. They come in a unique tank top style that makes them ideal for wear under a short-sleeve button-down shirt where you wouldn’t want the sleeves of a regular undershirt sticking out. 

Men who prefer buying clothing in a multipack instead of purchasing multiple garments separately will enjoy this set of four. Better yet, Fruit of the Loom offers these sets in varying colors. You have the choice of a mix of black and light grey or a multicolor pack that comes with burgundy, navy, royal blue, and grey. The only downside is that they don’t come in white. 

If you have a particularly hairy chest and find that your chest hairs tend to make an appearance through your button-down shirt placket, then this undershirt is for you too. It will keep your chest hairs in place, leaving you looking neat and dapper.

Key features 

When it comes to features, this undershirt offers many. Fruit of the Loom fashions them from 100% pure cotton. This is precisely the sort of fabric you want your undergarments to be made from, for many reasons.

Second, the weave of cotton makes it highly breathable, allowing air to circulate between your skin and the undershirt, regulating your temperature and keeping you from overheating. And lastly, it offers moisture-wicking properties too. This means that the fabric will wick away any moisture or sweat, keeping you dry and comfortable. 

These undershirts feature a rounded, crewneck neckline. This style is great for covering up those sneaky chest hairs that grow further up the chest that you don’t want visible to everyone else.

These shirts come offered in white or black. Whether you need a lighter-toned one for wear under a pale dress shirt or a darker one to fit under your black or navy dress shirt, you will find them here. 

When it comes to keeping clothing clean, there is nothing more annoying than an item that needs dry cleaning. Luckily these undershirts from Hanes are machine washable, so you can get them laundered and back in your closet, ready to wear.

Key features

Hanes fashions these men’s undershirts from 100% cotton, which means you can expect them to be soft and comfortable to wear. 

Cotton is often used to make undergarments because it allows air to flow through the fabric, regulating your body temperature and preventing you from becoming too hot or sweaty; this is called breathability.

The cotton fabric also wicks away moisture, so you’re left feeling dry, even if you do tend to sweat. This is particularly useful as the undershirt will prevent sweat and deodorant staining on your button-down shirt. 

Hanes designs their undershirts with a lay-flat collar that ensures the collar keeps its shape and doesn’t create visible lines under your dress shirt. They also prevent the undershirt from irritating the back of your neck by making it tag less by printing the label directly onto the shirt instead of sewing in an additional tag.

Polyester features moisture-wicking properties that remove moisture from your skin, leaving you feeling dry and comfortable.  

Neleus sews these garments using flat-lock seams to prevent chafing while you work out. 

These tank tops feature a crewneck neckline that keeps chest hair under wraps and wider armholes that won’t bunch or chafe your underarm area.

Specs 

• Made from 100% cotton
• Crew neckline
• Short sleeve
• Moisture-wicking properties

Who is it Best for? 

When winter comes around, an undershirt can add an extra layer of warmth that won’t cause you to overheat but will give you additional protection from the cold you need. If you feel the cold a little more than most, then this undershirt is precisely what you need. 

Men who are not fans of shopping will appreciate these. They come in a multipack of six shirts, so you have one for each day of the workweek and one for weekend use too. 

If you’re the kind of guy who likes a little variety, then these multipacks are for you. Gildan offers them in a single solid color such as white, or you can buy a pack that includes various colors such as black, white, and grey, or navy, grey, and burgundy.

Key features

Gildan’s undershirts are made from 100% cotton. These shirts are designed to protect your dress shirts from stains that result from deodorant and sweat. The cotton composition of these undershirts does just that. Cotton is breathable, allowing air to flow between your body and the fabric, regulating your body temperature, and keeping you from overheating. 

The cotton also wicks away any moisture, keeping you dry and confident and saving your dress shirts from sweaty patches. 

When wearing a t-shirt, there is nothing more annoying than a tag that scratches and tickles your neck. Gildan understands this, which is why they make their shirts tag less. They also tape the neckline and shoulders for added strength and comfort. 

The collar’s tubular rib design keeps your undershirt discreet and allows it to fit easily over your head and retain its shape. 

6. Gildan Platinum Men’s A-Shirts Multipack

When it comes to apparel, Gildan understands its customer’s needs. The brand recognizes that everyone’s tastes and needs are unique and that what works for one individual may not be as valuable to another. 

For this reason, the company strives to provide us with a wide range of choices, one of which is the Gildan Platinum Men’s A-Shirts Multipack. These undershirts offer a great alternative to the sleeved versions we reviewed above. 

Specs 

• Made from 100% ring spun cotton
• Sleeveless design
• Crew neckline
• Tag less

Who is it Best for? 

Men who frequently wear short-sleeve button-down shirts but would still like to wear an undershirt should look more closely at these. They feature a tank top or vest-style design that covers up chest hairs and provides a little extra warmth, but that won’t be visible by sticking out at the edges of your sleeves. 

If you’re not a fan of having to wash garments by hand or cart them off to the dry cleaner, then these shirts are just up your alley. They are machine washable and are pretty simple to care for. 

When it comes to shopping, convenience is often key, which is what makes this pack of six vests so fantastic. They are also offered in an assortment of colors that include black, grey, and white.

Key features

Gildan fashions these base layer vests from 100% ring-spun cotton. When a manufacturer speaks of ring-spun cotton, they refer to cotton that has gone through a process whereby it is spun in ring frames. This process leaves the fabric softer and more durable. This type of cotton is often seen as being superior to regular cotton. 

These vests also wick away moisture and provide breathability that prevents you from overheating. 

Gildan also covers the seams at the neck and the shoulders to provide additional comfort and prevent chafing. The crewneck neckline offers greater coverage and a little extra warmth on colder days. 

If it’s exceptional comfort, style, durability, and high-quality you want from your undershirt, then we suggest giving these ones from Gildan a try. 

7. Gildan Men’s V-Neck T-Shirts

As simple as the traditional t-shirt may seem, Gildan is well aware that this everyday garment is a little more complex than we realize. They offer the trusty undershirt in a series of styles that come with both long and short sleeves, but they also offer them in a crewneck or V-neck style. 

The Gildan Men’s V-Neck T-Shirts are not just any V-neck tee; they offer a comfortable option that sits neatly beneath your dress shirts for added comfort and style. 

Specs 

• Made from 100% cotton
• Short sleeve
• V-neck t-shirt style
• Breathable

Who is it Best for? 

If you often wear a dress shirt without a tie or a v-neck sweater, then these cotton V-neck undershirts are precisely what you need. Unlike a crewneck neckline, the V-neck plunges, so it won’t be visible when you wear other V-neck style apparel. 

Gildan is all about convenience, so if you prefer to buy something that works well for you in a multipack, you’ll appreciate these. They come in a pack of five or six undershirts, and better yet, they come in a range of colors too. Purchase a pack with a single color such as white or black or select colors that include grey, navy, and burgundy. 

These V-neck undershirts keep things simple by being easy to clean – pop them in the washing machine and you’re done. 

Key features 

There is nothing more uncomfortable than sitting in a shirt, especially one that hugs your form and feeling musty and sweaty. Gildan understands this, which is why they make this V-neck undershirt from 100% cotton. This fabric is moisture-wicking, efficiently removing moisture and sweat from the surface of your skin to keep you dry, cool, and comfortable. 

To help keep you from sweating, the cotton also prevents you from overheating by allowing air to flow through to your skin, regulating your temperature.  

These shirts come with a tubular ribbed collar that allows them to stretch over your head with ease and regain their shape afterward. The neck and shoulders of these shirts are taped for durability and to prevent the seams from becoming scratchy or irritating. To further reduce irritation, Gildan also makes these shirts tag less.

When it comes to buying a good undershirt, there are a few things to consider. This may be surprising because, really, what goes into choosing an undershirt? But there are quite a few things to keep in mind to ensure you get the one that best suits your needs. 

Take the time to consider things such as material, style, and fit before making your purchase. Once you have decided on these points, it will be a much quicker and less challenging task to sift through the multitude of options out there. With that being said, let’s take a closer look:

1. Style

Men’s undershirts come in a wide variety of styles. The style you opt for will depend mainly on personal choice and the type of garments you will be wearing these undershirts with. 

• Crew Neck:

The crew neck t-shirt is one of the more popular styles of undershirt – these come with a rounded neckline. While this style is often very comfortable, it also poses a problem in that the neckline usually sits relatively high. If you wear a garment over it with a lower neckline, your undershirt will be visible. Crew neck undershirts are best worn with dress shirts buttoned up and finished off with a tie. 

• V-Neck:

The V-neck undershirt is a lot more versatile than its crew neck counterpart. These come with a deep-V that plunges relatively low or a shallow-V that sits a little higher up. A shallow-V is excellent for wear with unbuttoned dress shirts, while a deep-V works well with a V-neck sweater. 

• Tank-Top:

A tank top is a sleeveless undershirt. These can come with a crew neck or V-neck neckline. They aren’t ideal if you are trying to eliminate sweat from your dress shirt’s underarm area, but they work well for sportswear.

2. Fabric

Undershirts are made from an assortment of fabrics. It bears taking note of the different materials used so you can tell more easily which undershirts are worth your time and money.

• Supima Cotton:

Cotton is the best fabric for making undergarments because it is light, soft, and breathable. If you want the cream of the crop when it comes to cotton, you want to go for an undershirt made from Supima cotton. This unique, long-fibered varietal makes up less than 1% of the cotton grown in the US, making it rare. The long fibers are stable and sturdy, making them softer and far more durable.

• Pima Cotton:

Pima Cotton is considered a step up from standard cotton. While not quite the same grade as Supima cotton, it features longer, softer fibers than regular cotton, making it softer to the touch.

• Standard Cotton or Cotton Classic:

Standard cotton is what you will find most undershirts are made from as it is a lightweight yet durable fabric that is breathable and wicks away moisture, keeping you cool, dry, and comfortable. 

• Organic Cotton:

Organic cotton is a form of standard cotton, but it is grown without the use of pesticides and chemicals, making it a more environmentally friendly option. 

• Polyester or Rayon:

Polyester is a synthetic fabric that is soft and breathable, like cotton. Rayon is a fabric made from natural cellulose fibers that come from wood and are then chemically treated. Rayon acts like both a natural and synthetic fiber. It is breathable and moisture-wicking like a natural fiber such as cotton, but it is drapey and resistant to wrinkles and creasing like spandex or lycra. Pure rayon on its own isn’t excellent as a fabric for an undershirt, but when blended with other fibers, it works pretty well.

• Modal and Micro Modal:

Modal is rayon blended with other fibers such as cotton and spandex. Modal is often used to make undergarments as it is luxuriously soft and durable. Modal is often far more expensive than cotton, though, so if you’re going to buy a modal undershirt, prepare to break your budget. 

• Lycra and Spandex Blends:

Lycra or spandex blends offer a more snugly-fitted undershirt. This fabric is often used for making compression base layers or sports undershirts.

When it comes to buying a high-quality undershirt, there is an assortment of things to consider before making your purchase. Taking elements such as quality, style, fabric, brand, and color into consideration will help you find the right undershirt for you more quickly. There is no point in trawling through the hundreds of options available with no firm idea in mind of what you want; it just becomes confusing and frustrating. 

We hope our reviews have simplified the task for you and have narrowed down the choices. If you find you’re still unsure and are looking for a little more guidance, our top pick goes to Amazon Essentials Men’s 6-Pack Crewneck Undershirts. These shirts are soft, comfortable, and are made from 100% cotton. With a combination like that, you can’t go wrong, and best of all, they don’t cost an arm and a leg.
