Undershirts for men aren’t just for layering; they’re the foundation of every solid, stylish fit, and they solve real problems. Think sweat stains ruining your best shirt before an important lunch, scratchy seams rubbing under a jacket, or that frustrating moment your shirt won’t stay tucked in. A solid undershirt handles all that without breaking a sweat—literally.
They might’ve started out as men’s underwear, but these days, they’re training in more than one lane; functional base layers and key players in fashion-forward looks. From slick-back seventies looks with belted suit pants and a white undershirt, or the trending retro gym style complete with a ribbed tank and pumper pants, the undershirt is stepping out of the background and into the fashion spotlight. And with layering trending as a core element in menswear right now, on TikTok, in street style edits, and even on runways, undershirts are having a serious fashion moment.
Still grabbing any old white tee and calling it an undershirt? It’s time to level up. Whether you’re looking for a functional tank top to layer under an outfit for a clean finish or to stay fresh under a hoodie, undershirts are the new basics. So let us guide you through how to choose the best men’s undershirts for every setting, sweat level, and style scenario.

The soft ribbed texture adds visual interest and a nod to throwback athleisurewear, while the low-profile cut ensures it stays discreet when worn as a base layer.
Best for Gym-to-Street – Critical Tank
This one’s got versatility locked in. Built for movement but styled for everyday wear, the Critical Tank is your go-to for workouts that don’t end when you leave the gym. It features sweat-wicking tech to keep you dry and a structured fit that contours without clinging too tightly. The classic athletic cut gives you room to move while showing off your physique.

Best for Cold-Weather Layering – Element Baselayer Top
The Element Baselayer is built for cold climates and active layering. It’s insulating without being bulky, thanks to its technical stretch fabric and second-skin fit. Whether worn under outerwear for your winter commute or used as a training base layer for outdoor training or cold-gyms, it traps warmth while allowing for a full range of motion. A must-have to wear under a pump cover or for transitional weather dressing.
How To Choose the Right Undershirt
Finding the right undershirt for men is all about balancing comfort, function, and how it plays with your outer layers. Here's what to look out for when it comes to layering undershirts:
Fit Differences
If you’re layering under a dress shirt or something tailored, opt for a slim, second-skin fit that won’t bunch and stays tucked in— ideal for long days at work or events where you’re moving around a lot. No one wants that bulky midsection or constant re-tucking.
For streetwear or gym layering, you’ve got more freedom: relaxed cuts that are slightly looser can work well under hoodies or overshirts. They offer more airflow and comfort, and they give that off-duty, effortless vibe.
Neckline
Crew necks are a classic base layer for sweatshirts and hoodies. V-necks work well under shirts if you want to keep things invisible, especially collared shirts, while scoop necks or wider cuts offer a low-profile option that stays hidden but can also work as a statement when styled to be seen.
You’ll often find deeper scoop necklines on ribbed tanks, making them ideal if you want something subtle that doesn’t show under open shirts, or prefer a peek of texture as part of your look.
Sleeve Length
Tanks are best when you want zero bulk—think gym layering or wearing with open shirts in the warmer months. Short sleeves offer a bit more coverage, while long sleeves make sense in colder seasons or under heavy outerwear for extra warmth.
Color
White is a go-to, but not always the best choice under white undershirts (opt for grey or skin-tone shades for that). Black works under darker fits, and beige or brown tones blend well for invisible layering. If the aim is to let the undershirt show, then go for any color. Here’s where it can be fun to play with pops of colors like blue, green, or red.
Fabric Features
Look for breathable, sweat-wicking fabrics, especially if you’re active or prone to overheating. Stretch and recovery are key if you’re wearing it tight. Anti-odour tech is a bonus for all-day freshness, just make sure you're washing your gym-wear right to keep things fresh for longer.
How To Style Undershirts | Layering Tips
Layering isn’t just practical, it’s a full-on styling move. And right now, it’s trending everywhere: gym fits, festival wear, clean TikTok aesthetics, even soft tailoring. Here are our layering tips on how to wear an undershirt for men like a pro:
1. The Clean Base Look
Start with a fitted ribbed tank or crewneck under a flannel, zip-up, or open overshirt. It gives your outfit structure and contrast, with just enough of an edge.
Weekend-ready? Try a ribbed tank under a short-sleeve overshirt, relaxed denim or cargos, and your sneakers of choice - chunky Asics for a modern city-style, flat Adidas sneakers for a retro touch.
2. Under Tailoring
Keep it discreet under a dress shirt or blazer with a scoop or V-neck undershirt that disappears under the collar. For smart casual, try a V-neck undershirt under an Oxford shirt (buttons open or closed), relaxed pleated pants, and clean loafers.
3. Gym Layering
You’ve seen it before; it’s the modern gym-bro uniform, and for a good reason, too. The classic ribbed vest and pumper pants combo. Physique enhancing, fresh and comfortable, it’s the perfect undershirt outfit for every season, from winter arc to summer fashion.
Pair a moisture-wicking undershirt with a zip hoodie or oversized pump cover. You’ll stay dry and look fresh on your way in or out of the gym. Or for a performance tank, slim joggers or shorts, fresh white crew socks, and a clean pair of lifting sneakers.
4. Loungewear Layers
Ribbed tanks and relaxed tees work great under soft hoodies or oversized sweats—especially if you’re chilling but still want to look put together. Grey sweatpants in the winter? A must-have for in and out of the gym. And if you’re heading out, a breathable tank or tee is ideal for adding bulk-free warmth as you layer up.
Think ribbed tank + open zip hoodie + baggy joggers.
FAQs
What’s the best undershirt for layering under a T-shirt?
The best undershirt for layering under a T-shirt is a fitted tank or lightweight crewneck that hugs the body and disappears under your tee. Look for minimal seams and a soft fabric so it doesn’t bunch or show through.
Should I wear an undershirt with a dress shirt?
Wearing an undershirt under a dress shirt is a great way to keep things looking crisp, especially if you're heading into long meetings or warm commutes. A V-neck or scoop-neck undershirt in a neutral tone won’t show through and helps protect your shirt from sweat, keeping it fresh and lasting longer.
Are undershirts meant to be tight?
Undershirts should be close-fitting, but not restrictive. You want a snug fit that creates a smooth base layer without bunching under your outerwear. If you're layering under tailoring, the sleeker the fit, the better.
V-neck vs. crew neck: Which is better?
It depends on the outfit and what you’re wearing over it. Crew necks work great with fully buttoned shirts, layering under sweatshirts, or wearing solo. If you plan on leaving a few buttons open, or wearing a collared shirt, a V-neck, or a scoop neck stays hidden and keeps the focus on your outfit, not the peeping base layer.
Do undershirts help with body odour?
Yes, especially those with moisture-wicking or anti-odour tech. Undershirts act as a barrier between your skin and outerwear, which can help keep things fresher, reducing odour buildup throughout the day.
Should you wear an undershirt to the gym?
You can definitely wear an undershirt to the gym; in fact, ribbed tanks are probably the number 1 gym trend for men right now. A sweat-wicking undershirt helps regulate your temperature and keeps your outer layers drier. Tanks or compression tops are ideal for workouts, depending on how much coverage or support you want.
Can you wear undershirts as standalone tops?
Yes! With the right cut and styling, undershirts, especially ribbed tanks or moisture-wicking fitted tees, can double as clean, minimal tops for everyday wear. Just add cargos, joggers, or an open shirt and you're set.
How many undershirts should I own?
A good starting point is 5–7 undershirts in rotation if you wear them most days. If you only wear them from time to time, say to the gym or for chilling in a few days a week, a good amount would be about 3. You can include a mix of tanks, short sleeves, and long sleeves so you're ready for layering year-round- whether that’s for work, workouts, or weekend plans.
