We think these are the best undershirts for men as nearly all are designed as a body shaper specifically targeting those with a bit of spread around the midriff.
Insta Slim 3 Pack Men’s Firming Compression Muscle Tank Shirt
These men’s slimming undershirts come singularly or in packs of 3 (for the price of 2). The sister company is Instant Figure, the successful women’s version of shapewear products.
After the success of advertising on TV infomercials, the company started with men’s compression shirts 30 years ago.
The slimming shirts are made of a single layer of fabric nylon 72% and spandex 28%.
They are lightweight although thicker than a normal compression shirt not designed specifically for drawing in the excess body fat and looking slim.
The shirt still has the benefit of drawing moisture away from the skin.
Getting the right size is important as the garment will keep its shape. It is made to stay elastic and won’t shrink in the wash.
The Insta Slim shirt is designed, fitted, cut and sewn in the US.
The company markets its product as a body shaper able to look up to 5″ slimmer immediately. And it does provide an immediate chest slimming appearance as well as modeling the love handles with its length (around 26″ on large) which can easily be tucked in.
A key feature of the Insta Slim shirt is its chest compression, enhancing the fit and silhouette of the garment.
This version is the classic tank top, not my favorite but there are also v-necks, and crewnecks, as well as shirt-sleeved models. The v-neck was my favorite – should have included a picture – sorry.
The colors available are black, white and nude.
These slimming tee shirts are machine washable – use non-chlorine bleach, tumble dry low or line dry and don’t iron.
30-day money-back unconditional guarantee – any postage not refunded.
Sizes go from small to 6XL.

Highlights:
- Totally made in the USA
- Good for gynecomastia (man-boobs) in particular.
- They are pretty long and so can be tucked in.
- No give so the tightness should remain.
- Good to wear underneath a suit.
Lowlights:
- The compression shirt tends to roll up so get ready to adjust.
- Material is relatively thick and there may be a problem in cooling if doing intense physical activity.
Gotoly Men’s Compression Shapewear Slimming Body Shaper Tank Top
Gotoly is another company, this time, based in Hong Kong that has specialized in women’s body shaper products and seems to have done a pretty good job with their waste cinchers, bodysuits and butt lifters.
This compression men’s slimming undershirt is sold as a single tank top, which makes it comparable with all the offerings we have here apart from the last on our list.
The fabric is another man-made blend of 80% Nylon and 20% Polyester with an extra layer around the abdomen.
This helps to pull in and give a definite slimmer look to the stomach. It also feels like there is improved support for the back which other users have noticed too.
I found this tank top shirt to provide a good deal of comfort during physical activity, especially my favorite, a HIIT workout. I think the smooth feel of the fabric, and lack of seams helped. The pressure was even and tight making it great for exercise for other physical activities.
The flat seams contribute to a lightweight and flexible design, enhancing the overall fit and feel for activities like running and workouts.

Underworks has been making men’s and women’s body-shaping garments since 1997 with their first successful compression shirt, the Zip-n-Trim brief.
The inner layer helps to flatten out bulges giving muscles additional support in the chest, tummy, and back regions. It has become popular with gynecomastia patients.
The Underworks ‘cotton concealer” compression shirt’s mix of layers and fabrics means a smooth and comfortable feel when moving in normal day-to-day activities or more strenuous workouts.
The light pressure exerted by the shirt aids in recovery and circulation, making it beneficial for post-operative recovery and enhancing athletic performance.

Under Armour HeatGear Compression T Short Sleeve Top
Now I’ve cheated a bit here as this Under Armour compression top is not specifically designed for gynecomastia (man-boobs) or big guys with excess fat around the chest, tummy or hips.
I’ve been wearing this as a sports compression shirt for years now. In fact, I’ve been wearing the same one for ages and it’s lost some elasticity, as you might expect, but it’s still going strong.
The Under Armour HeatGear compression shirt is rated medium compression. And not just that but it is made with gradient compression which supports the back front and sides.
It’s great as an underlayer to add a smoother shape to your figure and the 4-way stretch is well-designed to allow for total freedom of movement.
This compression shirt is made of breathable fabric which will wick sweat away efficiently. The moisture wicking fabric helps keep the wearer dry and comfortable during high-sweat workouts, making it ideal for activities like yoga and weightlifting.
This is one of the main reasons it’s my choice for the best compression shirt for most of my activities.
The fabric is made of 84% polyester and 16% elastane.
And if you’re looking for men’s long sleeve compression shirts then the Under Armour Heatgear has a version in a myriad of colors – over 20.
Highlights:
- UPF30 sun protection.
- Excellent at removing heat and wicking moisture.
- Medium compression shirt.
- Loads of colors to choose from.
Lowlights:
- Not specifically designed for heavyweights.
- May rise up a bit during more active movement.
Bonus Option
For those looking for versatile options, long sleeve shirts like the Lululemon men’s SenseKnit Running Long-Sleeve Shirt offer comfort and practicality with features such as moisture-wicking technology and thumbhole cuffs for colder conditions.
The seams are seamlessly bonded and the garment provides excellent ventillation which I found to be almost unnecessary given the wicking.
We like the quality but it doesn’t come within our specification of value for money.
5 Good Reasons for Wearing Men’s Compression Shirts
There are many reasons for wearing a compression shirt as an undershirt or as a statement at the gym.
- Compression clothing functions as a base layer particularly useful when hiking, for instance, because of its great wicking properties. Multiple layers also trap and warm up the air, maintaining body heat.
- In recovery and performance for athletes. Improving by small percentages. And as an aid for muscle recovery as the user wears the shirt for an hour or two after the exertion. Compression shirts help reduce muscle soreness after intensive workouts.
- For ‘normal’ people keen on their personal fitness levels – that’s where I think most of us fit – compression tops are perfect for holding those excess bits in while comfortably moving around during exercise.
- Men’s compression shirts as well as compression shorts help in the mindfulness of your muscles during physical activity and therefore help motivate you – I have found that feeling good gives me extra confidence.
- Slimming undershirts offer smoothing of the little excesses of fat around the chest and stomach.
- And finally, more critically, for men who have had recent surgery or who suffer from excess fatty chest tissue known as gynecomastia.
Swollen breast tissue in men
Gynecomastia occurs in males more often at birth, in puberty and in midlife into seniors. The main cause is an imbalance between the two gender’s hormones estrogen and testosterone.
Commonly called man-boobs breast enlargement is at its most prevalent in men over 50. That’s us, well me anyway!
We won’t dwell on the technicalities of the subject but for further reading for anyone interested the Cleveland Clinic has good information on the subject
There are clothing brands that are fully committed to helping those of us who haven’t got the ideal body but still want to look good and feel ‘secure’ whilst exercising.
Many athletes and fitness enthusiasts wear compression clothing for its benefits in muscle support and recovery, but it can also be advantageous for those with gynecomastia.
The properties of compression shirts still play a part for anyone doing sports or physical activity as they wick away sweat keeping us cool and comfortable.
For others with breast tissue issues or even too much love handle and beer belly, it may be about confidence as well. Good men’s compression shirts can be used as a slimming body shaper most of the time going about normal day-to-day business.
In another article, we have covered some stylish ways of hiding belly fat for women.
Will even the best compression shirt for slimming help with weight loss?
Well no! That’s the short answer. Although there are a number of benefits to wearing compression shirts that should help in maintaining and losing weight.
- Wearing one or more layers of compression garments should increase the amount you sweat. Although this isn’t the fatty substance you want to get rid of the moisture will be wicked more efficiently.
- Compression shirts mean that you will be held in tighter and should be more comfortable when exercising or doing other physical activities. The extra mobility and flexibility will improve the movements.
- Feeling and looking leaner gives more confidence and better self-esteem which would hopefully be a motivator in toning up those muscles.
- One design feature aids blood circulation and across muscles and gives them support. Again this can help to motivate to exercise.
So all-in-all compression vests are positive for weight loss but not exactly instrumental in helping to lose weight. The best men’s slimming shirt will be a mental aid in the fight against the flab.
Compression means “tight” right?
One of the main differences we found between a normal compression shirt and one specifically for holding those fatty bits in, was the increased robustness of the materials.
The design of the gynecomastia compression shirt is different too, as many were enhanced with extra panels and inclusions within the material.
This makes them more difficult to get on and off. Something to bear in mind. Having said that the maker’s charts used to select the correct size are accurate so stick with that, which means the same size as your normal clothes for the best fit.
It may seem that such a lightweight item might seem an impossibility at first to get into.
I prefer short sleeves myself as I find the armpit area more comfortable if covered. Trying to get into or out of a compression long-sleeve top can be a bit trickier than short-sleeve compression t shirts. A no-sleeve top would be even better, of course, but won’t act as a body shaper so well.
For an alternative way of getting a tank design on, hold both straps of the shirt and step into the garment. Pull up the garment and slide arms through the armholes and tweak for comfort.

Do body slimming undershirts work?
The better compression shirts will help pull in the unwanted flab and make you feel and appear more svelt. But too much flab may be too much for the garment.
Do compression shirts make you slimmer?
Compression shirts won’t make you slimmer. If you have a great bod they will accentuate it if it’s a bit flabby a compression shirt will help to conceal it.
Is it OK to wear compression shirts all day?
Yes, it’s okay to wear compression shirts all day. Mens slimming undershirt shouldn’t be uncomfortably tight and be restrictive. For some medical conditions, it’s advisable to wear compression clothing all the time whilst recovering from injury
Does compression restrict blood flow?
Compression doesn’t restrict blood flow but rather helps blood flow through the body better. Compression prevents blood from pooling in the body.
