I just received this shirt in the mail. It meets all my expectations. I work out quite a bit but just can’t make the gains that I want. This shirt puts me over the edge to be just where I want to be. Need some bigger sizes for the bigger guys that just need a bit more to be where they want to be.

The padded muscle shirt is truly amazing. Every time friends and family see me they mention how great I look not really knowing what was making a difference. I am 6’2” and very lean and thin. I find it almost impossible to put on mass the padded muscle shirt instantly enhances my physique. Clothes have never looked better on me. Thanks to Rounderbum.

Hey, this product really came in clutch for me. I had a photoshoot after surgery, and I had lost some weight. Wearing this made me feel confident in my outfit choices.

Benjamin P. 5/5 Verified

Love the fit and the feel. It gives a subtle boost to the areas I'm focused on improving. Wearing it really inspires me to workout even harder!

William S. 5/5 Verified

I love wearing it, gives me more confidence in public.

Dennis O. 5/5 Verified

Glad I bought a size up. This fits very snugly, which is a good thing. It does flatter the shape. Didn’t occur to me that because of the arm pads that extend to the elbow this can only be worn “stealthily” with a long-sleeved shirt. And because it only comes in black… a DARK shirt.

Robert 4/5 Verified

Perfect fit and seamless.

Douglas 5/5 Verified

Better than the non stealth version.

Eric 5/5 Verified

I put the muscle shirt on and then a turtleneck sweater over it and wow, it looked and felt real

Robert S. 4/5 Verified

This fits so well. And looks so real!!!

Jeffrey D. 5/5 Verified

I bought one and I was surprised how good it made me look. I only wish they made this in white or nude color since the black shows through white and light color shirts. I’ll be checking back for hopefully more colors.

Shahram V. 5/5 Verified

Very discreet and gave me an idea of what I look like when I bulk up

TY

Troy 5/5 Verified

Just as great as the first one. Love it

Robert 5/5 Verified

Padded in right places.

William 5/5 Verified

Fits true to size

Bernard 4/5 Verified

Excellent sizing

Francisco 5/5 Verified

Works as intended however the size runs extremely small. Would recommend sizing up an extra size to fit comfortably. Also very hot non breathable material. Wouldn’t recommend wearing in the summer.

Elliot 3/5 Verified

I definitely stood out from the crowd when wearing this.

Justin 5/5 Verified

Perfect

Dario 5/5 Verified

This product is best for the guy who is on the thinner side, yet fit. It will make you look bigger and stronger. Just hope nobody grabs your "enhanced muscles." lol

Scott S. 5/5 Verified

The fit on the chest and upper arms (I ordered an XL) is fine, however it is slightly tight under the arms (this I can find with other T-shirts)

John P. 5/5 Verified

I am very happy with the Padded T-shirt with removable pads. The chest pads are bigger than the regular padded t-shirt and look more natural on me. I think only men with a smaller frame would do better with the regular.

Louis R. 5/5 Verified

very nice product , very happy with it

Francisco R. 5/5 Verified

Hides easily under shirts.

Wilbur S. 5/5 Verified

Absolutely great product,love the material. Definitely look another one. My only issue is no choice of color. Would be great if you could give us color choices. Most I use bright colors and with black,hard to use it on white shirts.. absolutely recommended

Robert 4/5

Honestly it was better than I expected. It wasn’t cheap but you get what you pay for. Thank you!

Bradley G. 5/5 Verified

Makes a difference, and yet, no one really notices, but I do and that’s just fine with me.

Frank S. 4/5 Verified

I am so amazed at how realistic the extra muscle looks. I tried it for the first time today and I have received so many compliments. It’s just enough added bulk to notice and still look believable. Thank you!

Marc W. 5/5 Verified

I'm very satisfied with the fit! I'm 5'5/6 and the Small size was perfect. Looks very natural and the material is comfortable

Joey 5/5 Verified

Fits great! It inhances my upper body wonderfully. Love it. ...will be ordering again.

Herman S. 4/5 Verified

The product does what it says and is also very comfortable to wear. I would highly recommend the padded boxer briefs to anyone who wants to look better!

Michael B. 5/5 Verified

Fantastic, I have just a natural feeling of confidence as my family and friends don’t seem to notice that it’s not real muscle. Padded fusion is incredible with the seamless design. Highly recommend!

Alex R. 5/5 Verified

Great

FAQ about shapewear

Do men use shapewear?

Men’s shapewear is on the rise — and for good reason.

More guys are asking, “Why should only women have these options?” From all walks of life, men are shopping shapewear to look and feel their best. Whether it’s smoothing love handles, lifting your butt with padded underwear, improving posture, or recovering post-surgery — men’s shapewear does it all. And let’s be honest — who doesn’t want a more toned, confident look?

Is it good to use shapewear?

There’s nothing wrong with wanting to feel your best — and men’s shapewear can help.

It’s great for improving posture, supporting post-surgery recovery, and boosting confidence for special events like weddings. Whether you’re looking for a more lifted look or just want extra comfort during long days, our men’s padded underwear delivers both support and style.
