Best Slimming Undershirts for Men of 2025

"I’m 6'3 and 230 lbs and bought an XL. It's very comfortable and helps my posture! I've received compliments, and I’m extremely happy with this purchase!"

"I found the fit snug at the chest, which might help with man boobs, but it didn’t do much for my gut. It just made my stomach look bigger. I guess it’s okay for wearing under a dress shirt."

"I bought this for a cleaner look under my dress shirt and it worked perfectly. I’m very happy with how it looked! It did exactly what I needed."

"At 63 years old, I've lost 60 pounds and these compression shirts have transformed my look. After just 3 weeks, I received compliments about looking trim instead of just thinner. I'm 6'6” and weigh 220 lbs, and the XL fits snugly, which is what I wanted. The tank tops are my favorite and I keep buying them. So far, they seem to be of high quality without any signs of wear."

"This is an excellent compression shirt. I've tried various brands, but this one is my favorite. It has some extra material around the middle that really helps tighten up my beer belly. It's very comfortable and does exactly what I need it to do. The size chart was spot on!"

"I needed to fit into a shirt and pants after putting on a few pounds, and this shirt has been a game-changer. I ordered two and they really hold everything in, making me look two inches slimmer in both the waist and chest. I was worried it would make me sweat, but it does not. I even wore it for NYE!"

"I bought this for my transition journey. It worked wonders with my binder, really slimming my torso and helping my clothes fit better. I found it very comfortable and durable, though it’s not the most breathable. I wore it under my underwear for better shaping and it did the trick. I'm currently in size XL tops, but this tank is keeping me at L."

"Overall, I'm pleased with this shirt. It arrived nicely packaged and the fabric quality is impressive. I can wear it all day without discomfort, and it effectively addresses my gynecomastia. It's been a solid purchase for me!"

"This compression shirt is really fantastic! It fits snugly without being overly tight, and the breathable fabric keeps me comfortable during workouts. I highly recommend it for anyone needing reliable compression for daily wear!"

"This is my first time ordering a compression shirt, and I found it very comfortable. It does exactly what it promised!"

"I bought this shirt to help with my loose skin after losing 50 lbs. It’s thicker, tighter, and really gives me the confidence I needed!"

"As a big guy, I still like wearing slim fit shirts. This one made me feel good, and I received several compliments on my body the first day I wore it!"

"I’m 6'2" and 215 pounds. Initially, I ordered an L, but it was too tight. I switched to 2XL, which fits better, but I just ordered a 3XL for a more flattering look. Unlike other neoprene, this one doesn't make me sweat, which I really appreciate!"

"I've been buying compression shirts for years. I'm 5'11", and my weight fluctuates but I've been over 300lb recently. I started with an XXL, but went down to an XL for a tighter fit. The difference is incredible; it actually flattens my chest better than anything else I've tried. I can move freely and don’t feel pressured, so I'm getting three more."

"I have an aversion to stretchy fabrics, so I was concerned about the material. However, after a few minutes, I completely forgot I was wearing it. I bought this almost a year ago and it has not lost its compression. Just a heads up: don’t trust Amazon’s recommended size. I wear a Large, and it fits perfectly."

"I recently got this shirt and I absolutely love it! The material is slightly thicker than others I've used, and it provides a nice snug fit that keeps everything in place. Unlike other brands, it has a smooth finish, so it’s not noticeable under my shirt. I’ll definitely be ordering more!"

"As someone who's working on minimizing chest dysphoria, I found this shirt to be generally good. However, I got the smallest size, and the straps are a bit long for me. This means the compression fabric doesn't fully cover my chest, which is annoying. The compression around my stomach is quite effective, though!"

"I was skeptical at first, but after trying this compression shirt, I was extremely satisfied. I’m about 5'7", and I ordered a small. It looked small when it arrived, but it fit perfectly. It provides support for my back and has a tightening effect on my midsection, which is exactly what I wanted!"

"This compression shirt is a game-changer for me! It gives me a more toned look and feels great during workouts. I highly recommend it!"

"I can't imagine hitting the gym without my compression vest now. It keeps me cool, dry, and focused. The slimming effect is a bonus. I highly recommend this for serious athletes!"

"I appreciate the high-quality materials used in this product."

"The durability is impressive; it withstands daily use."

"I love the attractive design that fits my style perfectly."

"Having bought compression shirts for a while, I stumbled upon the Eleady brand. I felt confident making this purchase and I'm thrilled I did. I've got four shirts now in different colors. After losing weight, I find that these shirts make my clothes fit and look better, boosting my self-confidence. They really do what they promise—helping you feel less jiggly and more toned. I give this product 5 stars!"

"I rely on compression garments for activities like lifting weights and for long gigs with my guitar. This material provides great support for my lower back without being itchy or irritating. I've waited to review until I saw how it holds up after several washes, and I can confidently say it’s a very good product. Highly recommend!"

"I recently got a Large size and it fits me perfectly. At 5'11 and 187 lbs, putting it on was a bit of a challenge, but once it's on, the compression is noticeable and impressive. It's a little long, but I'm pleased with the shape change I noticed after just one wear. I'm excited to see how it performs in the humid weather!"

"I bought one to test the fit and ended up ordering more because it fits perfectly. The fabric is light and stretchy. It was a bit of a challenge getting it past my wide shoulders, but once on, it feels great!"

"As a small guy with a 29-inch waist, I found the small size incredibly tight. I wished to return it but missed the window. I think my shirt might have been a defect, as I doubt any adult male could fit in a small. Still, I gave it 4 stars for the laugh."

"After losing over 140 lbs, I needed something to help with my excess skin. This product isn’t a body binder, but it does a great job of smoothing things out. It provides more support than other shirts I’ve tried, and the fabric stays in place without shifting."
