These fit great and are super cute! They are so comfortable and look amazing on. I’ve gotten a lot of complements and plan to wear these around the house all the time!

RAINBOW Lift Boxer

RAINBOW Lift Boxer

The most comfortable pair of boxers of ever worn!!! There sexy and stylish while having added lift support for your junk and back side. Couldn’t ask for a better pair of boxers. Will be ordering more. THANK YOU ROUNDERBUM!!!!!

Store owner replied: Thanks so much for trust and support Will! We are so happy you are enjoying your product! :)

Super comfy, right size, and so sexy

RAINBOW Lift Boxer

I love the look and the website is real simply laid out but the issue I have is with the inside capabilities. Though I have an XL waist I have more than the pouch allows but unfortunately my bum isn’t XL. I’d like to be able to have the insides more customizable than just one “common” design.

Store owner replied: Thank you for your balanced review Trent! We will take your valuable comments to take the correct actions and improve the Quality of our products and services!

This was my 3rd pair and just as sexy as the others. Without them I can see the difference between a flat look and a nice round look. Absolutely love this brand! Also get lots of stares!

RAINBOW Lift Boxer

Store owner replied: We're happy you had a fantastic time with us!

Super cute, comfortable, and I loved that they sported Pride

RAINBOW Lift Boxer

Store owner replied: We're happy that you're happy with your boxer :D

Very comfortable. Love the colors.

RAINBOW Lift Boxer

Absolutely love this brand! These were my 3rd pair and are just as sexy looking as the other pairs I have. Instead of having a flat look, noticed a difference with these on underneath which been getting a lot of good stares. Very comfortable to me.

RAINBOW Lift Boxer

This design is cute and I loved that it supported Pride Month. I’m wearing them now, and they fit perfectly. The quality of the material is one of the selling points for me.

RAINBOW Lift Boxer

Nice for walking around at home and whatnot, I would recommend getting your normal size so that the straps give your cheeks a little squeeze ;)

RAINBOW Lift Boxer

I own at LEAST one pair of every color... so amazing and comfortable.... plus I get tons of comments on them!!!

RAINBOW Lift Boxer

Store owner replied: Great Joseph! It's always a pleasure serving you. Thanks so much for your review and positive feedback.

I liked these for the look. They just weren't as comfortable as others with the lift tech because the elastic bands aren't sewn into the fabric, but rather are free like a jock strap. But still cute.

RAINBOW Lift Boxer

I love them all of these so much, I ordered two pair of these... I now have them in EVERY color!!!!

RAINBOW Lift Boxer

This is a great product to wear around the house and whatnot, and the color scheme is on point! For most Rounderbum underwear I’d recommend getting a size larger than traditional underwear, but for these ones I probably could have gotten my usual size (M instead of L) and it would have been fine.

RAINBOW Lift Boxer

Store owner replied: We're happy to see you are having a fantastic time with us!

Just another style from Rounderbum that makes me feel so sure and sexy. It lifts and accentuates. I love it.

RAINBOW Lift Boxer

Great to see Rounderbum put out this new product. Love the colorful design and the hidden lift effect. This looks like a winner!

FAQ about shapewear

Do men use shapewear?

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.
