Love these
Nice padded bulge and added cushion in the back wear them under some swim shorts to keep people wondering or wear them on their own they look and feel great .

Thank you very much Jose! Hope to hear from you again very soon :D

Looks great but…
I would drop the logo H2O as it gives away that it’s a padded suit. I would not wear it in public because of that. Too bad as it is a good product.
