No noticeable difference and band would not stay up in the back.
Amazing underwear i absolutely love them they fit amazingly anf feel amazing too. I would definitely recommend
Love it
Love it!
I dont see much difference, but they are comfortable.
Ok
I’m female. I ordered your fantastic product after exhausted search for a women’s booty lifting COTTON (or partially cotton) brief. I modified your boxer brief by cutting for a bigger lady tush and filled the gap. They are so comfortable! Love the leg length, love the waistband, except for the giant letters. If you alter this pattern just a little for women, you would have the ONLY cotton based boxer briefs butt lifter on the market. Women’s shape wear is a huge market. Please! Please!
Store owner replied: Dear Deanna Thank you so much for letting us your amazing purchase experience. We assure you we will make this is heard by he correct department so we can meet all your expectations in a near future :)
So I found these to be the most comfortable and best looking underwear I currently own. I do have an expensive collection. These are great these are not for enhancements but they look great . They fit so well.
Store owner replied: Thank you Edwin We’re really grateful and appreciate you taking the time to share your rating with us :)
I'll admit that I was a little thrown off by how these look. Once I put them on, that's when I was convinced. Already bought the blue ones!
Store owner replied: Glad to know you like it! Thanks for your preference and support :D

I really like the overall fit of these boxer briefs. They keep everything place and make my butt look great. The design is also very sexy, with various fabrics, textures and pouch design. I will definitely be purchasing more.
I have bought several styles of boxer briefs. They are so comfortable as well as great support! Well worth the cost!

Feels great. Love the way they feel and get compliments
Comfortable
The look and feel is good. I normally buy size large, but these seem a bit too snug, I will try to order one size larger next time. Otherwise, the quality and shipping speed are both very good!
Store owner replied: Thank you Scott, Sizes run smaller than conventional underwear, please consult our size chart for a better fit :)
The fit is good Except around the waist, it tends to slide down only if there was a little bit of grip around the waste
Comfortable
Doesn’t have the butt lifting tech, but great at keeping my balls comphy.
I've been buying my underwear from a company for the past 12yrs, when I came across this brand I'd decided to try em out. Love how they feel & give me a lift, now to find one that has a pouch & lifts my ass would ve great. Not a big fan of just white or black! I enjoy color & kool styles.
If you already have a fuller bum and more muscular thighs.....like me....LOL, these undies will need to be ordered a size up. The v-back takes a little getting used to also. Nice material and fit overall.
Very comfortable but at the same time it keep my butt and legs in tension
Store owner replied: Glad to know you like it :D
Tight at the thigh opening, can't wear these on or after leg day. Otherwise comfortable and do what they're supposed to fit-wise.
Excellent quality, design, fit perfectly, help to feel comfortable, and feel even more self-confident
Great fit and support.
Love the fit and feel. Don’t care for the big rubber lettered branding on the waist band. A simple branding print on the inside would do just fine.
Store owner replied: Thank you so much for your comments Kevin, we appreciate you took the time to share this with us ;)
Love these but would like more room in the crotch.
I love these boxer briefs! It provides support both front and back and gives a nice lift on your butt. It also "go with the flow" on your package!
Store owner replied: It's great to hear that you had a 5-star experience purchase with us. On behalf of everyone at Rounderbum, we thank you for your business :)

Store owner replied: Dear Rabbab A. It's our pleasure to know you received this excellent attention and service, our Customer Support Team will be very happy to know about this 5-stars review ;)
High quality material. Not sure which size best fits my body because I lose weigh or try during the summer. Feels good. I like the Anatomic mini trunk the best. Just wish they are more Affordable. Thanks
The GF says she likes them I can see they show the curve alot more than other boxer briefs
The panties I bought are simply breathtaking - really comfortable, fun, sexy ... Shipping was extremely fast and this despite the fact that I ordered from a country that is outside the US. The customer service is one of the best I have experienced - they took care of everything and did everything to solve my problems. I really thank the team and I hope to purchase from you again!
Store owner replied: Wow, Daniel! Thanks so much for sharing this with us, our team will be so excited and happy to read your amazing comments! :D

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.
