Excellent fit. Love them!
Feels tacky
This is a visually spectacular bathing suit. Mine was padded and it looks great on me. My only issue is it is not instant dry due to padding. Fits well and looks good.
Had the chance to use it on the beach at Waikiki. It's a good looking swimsuit, held up well in the sun,sand and surf. I ordered a medium, it runs just a little small, nevertheless loved it!
I wore it once and it looks nice. It feels very Padded. It makes a style statement.
It’s okay… all of their booty padding looks a bit like a loaded diaper. Not quite natural looking. This pattern helps disguise it a little better than some of their designs.
Received wrong size! Ordered XL and received a SMALL!! The material was also poorly made. Please help me with a Return Authorization Number as soon as possible! Thank you..
Horrible fit. Feels like a diaper. Not happy with it and not happy that i cant get a refund or smaller size.
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.
