Thanks for sharing your experience with us Michael, hope you enjoy your products! :)
3 separate times i gave my address and each and every time it came back via the carrier (usps) can’t deliver and the same address every time i replied with. No other packages i get, and i order several times a week from Amazon to Uber Eats, HEB grocery, and the lot of them. Rounderbum LLC it’s not me it’s You. I gave it three attempts and finally just asked for a refund.
Love the noticeable lifting effect it gives to my already round cheeks, l usually wear size 31 or 32 waist, and l got the large size, it fits perfectly!
I have owned jock straps in the past but none like this. They fit comfortably and really do lift your bum. Also like how flattering they make my butt look. Would highly recommend.
Feels so good. I love the way it's fit to the body. Although I'm wandering if the pouch in the front could be a little more spacious. Still I recommend it.
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.
