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.

Dear Sam
Thank you for your glowing review! We're thrilled to hear you enjoyed this Padded muscle shirt. Looking forward to serving you again :)
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.

Thanks for sharing your experience, so thankful for amazing customers like you!
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.

Glad to see you had a great purchase experience!
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.

Dear Shahram V.
Thank you for letting us know your comments, your feedback helps us to get better, be sure this will be shared with the correct department so we can meet your expectations in a near future :)
Very discreet and gave me an idea of what I look like when I bulk up
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.
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
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.
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

Thank you Frank, We are so excited to know the muscle shirt met your expectations! :D
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!

Looking forward to hear from you again Herman!
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!

Dear Michael
Thanks so much for these awesome review and for taking the time to share our experience!
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!
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.
What does shapewear do?
At Rounderbum, our goal is to help men everywhere feel great with shapewear.
But it does more than just boost confidence — our padded briefs add lift and volume to your butt, helping clothes fit better and adding comfort during long flights or desk time. Our compression shirts aren’t just for shaping your torso — they support better posture and are a great option for post-surgical recovery too. Shapewear isn’t just about looks — it’s about feeling good all around.
