Los productos a la primera lavada se les hicieron hoyos, ademas la paquetería ESTAFETA promete llegar a mi domicilio, pero no es asi, me gustaria que el sitio web permitiera al usuario elegir con qué paquetería trabajar, pero no es así, asignaron a ESTAFETA y nunca llegó a mi domicilio, tuve que pagar para ir por ellos a la ciudad más cercana. Un verdadero asco comprar con Rounderbum.
El color es muy vivido. Se acomoda bien a la nalgas y el bulto
Muy buen producto, se le ve genial a mi jovio

Súper
really good underwear, really makes my package look bigger. Not that I’m small, mind you! It’s not ego, the reality is I’m larger than average.
Perfect fit and comfortable
Fun product
The O My God series is what the name says. These feel so good I wish I could just wear them and nothing else. They feel that good!
Looks nice. True to 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.
