Sad to report that I am very displeased with this product. Padding isn’t natural looking at all. 100% noticeable. Threw it out immediately. Do not recommend.

Quality of the fabric and all is great! Wish they were a bit larger on the sides, but overall love them. Extra in front and back keeps me looking better which is all that I wanted. A little boost front & rear! Yay!
Love the fit and feel of the swim briefs! Liked that they were all black like my normal speedos!
Perfect as described
Perfect
I’ve never worn a swim brief before but with the back padding, I decided to take a chance and it looks amazing! That little extra in the backside was just enough to give me the confidence to show off the rest of my body and, honestly, it felt great. Absolutely will be buying more!
