I have the same to say as everyone else about this product. My only complaints are that it doesn’t come in a size that can accommodate my 84-85 inch wingspan, so they ride up a bit. I believe they would look better if it wasn’t a V-neck and covered the upper chest too. Also, if there was padding for the rear delts and upper traps, it would give a more balanced and powerful appearance. Aside from that, I have nothing but good things to say and would recommend it.

Hearing how much you love this product has brightened up our day at Rounderbum. W2e will make sure your comments are hear by the correct department so they can be taken into account ;)
Thank you Xavier!
Great product, nice fit and is completely as advertised. Two suggestions: make the sleeves a little shorter so it may be worn with a short sleeve shirt without showing under the shirt's sleeves, and can you make a white version of it? Otherwise...kudos!

Dear Joseph
Thank you for your gracious words! We’re delighted to hear you are enjoying your Stealth Lift Trunk . Providing exceptional experiences is our top priority, and your feedback motivates us to keep exceeding expectations.
Thank you!
Fits well and does create a great natural enhancement to body shape.
I was very skeptical about this at first. But it is a very tight fit in the padding is in the perfect place. Just gives that extra boost of roundedness and confidence! Hope to have the option to buy it in the color white soon.
This is my go-to undershirt when I want to fill out my button ups a bit more! I've ordered two and placing third order. Much better option than the pads that you have to take in and out!
I lost some muscle mass and looked for a quick fix. This did just that. With a tighter shirt on, you have a more athletic appearance. I wore it to meet a friend I haven’t seen in awhile and she was really impressed. Actually motivated me to start back up at the gym. It does fit small so order a size up. I’m 165 and a large was just right.

Glad to know you like it! Thanks for sharing your comments :D
Good Quality, Achieves The Product Description For Good Results
I haven’t mastered how to keep it tucked in
So that the pecs /torso stays in place without riding up…
The arms stay in place
Wonderful comfortable as well as undetectable! I’ve lost 60 pounds in the past 7 months and lost all my muscle tone. I was skeptable at first when I purchased the shirt but now I won’t leave the house without it on. You don’t even feel that you’re wearing it and it stays put all day without the padding shifting. I recommend this highly if you want a little enchantment for your upper body. Will purchase another one again soon!

Thank you for your trust in Rounderbum!
I am a wardrobe designer on a tv series. We used the Padded Muscle shirt for an actor playing an AllBlack rugby player and didn’t have the time or budget to make him do a work regime before shooting began. Super natural appearance and feel and the actor was extremely happy with how he looked which helped with his confidence. Will definitely use again. The director also wants his own set now!

Dear Edwin
Thanks for sharing this with us, we will make sure our Design team takes into account your suggestions ;)
Nice product... the construction could be better with minimal to no added cost. Edges of foam pads should probably finished better with a whip stitch. The sizing is a bit short. I'm only 5'10" and the small size I buy tends to ride up. Add 2-3" to the length. The bottom of the chest pads hit the bottom of my nipples. Would be great if they extended down another 1/2 inch.

So happy to know you had a good time with your product Sir! :D
I didn’t have high expectations for this but I was completely surprised when I tried it on and it looked great under my shirt. Very little padding but effective in making it look realistic and not bulky or like I have pads on. Will definitely buy again
Store owner replied:
Thanks for the awesome review, David! We work hard to meet expectations like yours, and we’re happy to hear we hit the mark for you!
These shirts put the padding I. All the right places to enhance your upped body shape. I like that the pads are sewn in over the other removable pads. I wish there was one more larger size.
Store owner replied:
Thanks Ruben, hope you enjoy it!
do you think you guys will come out with neutral colors so we could wear under light colored shirts? The black will show though if i decided to wear a white or light colored shirt.

I would like to say so far I'm happy with the shirt it fits me well and the definition is good so far. I feel like the fabric of the shirt could be a little better but overall I think this is a good shirt. I recommend this for people who feel like their too skinny and are having trouble gaining muscle and also want to look better in shirts.
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.
