It is comfortably perfect and gives me the mini lift I need
Awesome product
Love them. They are comfortable and makes me look more symmetrical without adding too much padding and also lifts things into place. Wish there was more colors and designs options
This is exactly what I was hoping for in terms of quality, craftsmanship, and fit.

Great concept, but wish the padding was removable and the fabric was softer/thinner.
These feel so good on and make such a difference worn under dress pants
I have purchased this brand for years but it is important to order 1 size larger. I am now a 30 or 31" waist wand wear a large. When I was 33 or 34 I wore and extra large.

Store owner replied: Thank you for your comments Andy Yes, products run smaller than conventional underwear. Its important to order either one size up or to consult our size chart ;) Thank you!
This Rounderbum padded brief looks so natural and gives me a sexy behind. Fits just like regular briefs. Unnoticeable padding even without pants. Looks just like regular underwear. Makes me look like I have a really nice ass.

Store owner replied: Thank you! Hope you are having a great experience with your undies :)
I love using this to buy my five star underwear!
I will say the bulge inhancing pouch most definitely works. I can't tell about the pads in the back.
Does what it says and more ;)
It would be nice if you could make the package cup wit an opening to add an additional cup like your other briefs
The fit of these briefs are very nice and the construction seems to be quality. The padding is subtle and effective and makes me feel more confident, will definitely buy again!

These are great briefs and very comfortable
I absolutely love your product. The last 2 pairs I ordered were slightly larger than previous pairs I have. The stitching on the package portion is not as smooth as previous pairs that I have.Seems as though the quality is not quite as good. Overall I love Rounderbum.
Wished thY they come in different colors
Definitely great for a pancake ass

Overall experience was good I have a couple returns to make so I have to see how they treat me in that respect but product quality is good. I’ve washed my underwear 23 times already, and it holds up beautifully the padding for the top, but it is quality and I feel more confidence when I wear them I look around at some of my coworkers guys my age, younger and older, and I see the droopy drawers. I’m glad that my my pants fit better.

DESPITE THE INITIAL DELAY IN GETTING THE PRODUCTS TO ME (MAYBE A RESULT OF MY BEING ABROAD) THE PRODUCTS THEMSELVES ARE WONDERFUL. COMFORTABLE TO WEAR AND STUNNING TO LOOK AT!! WILL BE RETURNING TO YOU CERTAINLY. THANKS A LOT FOTIS
Really love the fit and how they turned my flat ass into a fab ass!
All my life I have been a thin guy and small in stature, which made me very self conscious about my body. These definitely gave me a confidence boost! I look amazing in them and have gotten many compliments. I would totally buys these again!
very nice and comfortable, wish they were just a tad bit more padded or had lift tech along with padding tech
LOL… I guess it really works! I wore them twice, the 1st time I wore them I had someone smack my backside and said… niiice…. The 2nd time I was out having a beer with friends standing at the bar when I turned around and noticed someone taking a photo of me from behind… I laughed but was like WTH? They said they couldn’t help it, it had to be done! So again I say, it works! 👍

I love you guys products, but every time yiu guys have a sale you don’t have any mediums available.
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?
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.
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.
