United StatesGreat slimming boxer
Love this product. I purchased three and will likely be back for more. The fabric is high quality and the belly slimmer has the power and elasticity to make a real difference. While I do not have a big belly, I just wanted those slight side rolls to disappear. The silicone coating on the inside of the top elastic band keeps the brief properly positioned and prevents the waist band from rolling down. There are a couple reasons I give it a 4 rating. One pair has a side seam that is unraveling (a defect). I wish the butt pads were of better quality. I inserted some other pads that will hold up better and are a bit firmer, giving me a little bigger lift where I want it. Roundbum needs to invest in better quality pads.

Dear Robert We truly appreciate you took the time to share this valuable feedback with us, rest assure your comments will be taken into account so we can provide an even better experience next time :) Thank you!
United StatesThis is the best .
Hi I am 5 foot 7 inches tall and I weigh 140 pounds. I ordered the Slim Fit & Padded Boxer Brief in size Large and it fits perfect. I normally wear size medium in underwear but I knew this item runs one size smaller. So I ordered one size up from medium, which is a Large and I am glad I did it’s perfect and very comfortable. I like the high waist on these because it helps shape you if you have a little belly and the high waist has some kind of thin rubber lines on inside top of the waist to hold it in place so it will hold roll down on you as you more around. The padding on the butt is fine and looks good once you put your pants or shorts on. Also the quality of the material is top notch and so is the craftsmanship. Ordering was easy. Fast shipping and great packaging. I am very happy . Thank you for an amazing product.

Dear Sir Thanks so much for taking the time to leave us your rating – it’s much appreciated! We hope we can hear from you again very soon ;)
United StatesLove it!!
These fit perfect, pad could have been a little bigger. I had weight loss surgery and lost all of my butt. This has helped me tremendously. THANK YOU!!

We are happy to know we were able to make a difference for you!
United StatesGreat product and support but.....
They do not sell replacement shoulder pads, so if you lose one, you'll have to take the other one out to give an even look. Also, they've been out of the shoulder pad shirt in my size for quite a while.
United StatesLooking Good
My neighbors could not believe how good my rear was.
