Best men's padded bulge-enhancing swim briefs

Top pick: Rounderbum H2O Waveform Padded + Package Swim Brief — the only one here that's genuinely padded and built with a package-enhancing pouch, which is exactly what you asked for. It's a purpose-made swim brief from a brand known for this, so the padding sits where it should and stays put in the water. Its rating is middling, so read the fit notes before you commit.

Who the others suit:

• Mr Saker Padded Swim Brief — the crowd favourite: highest rating of the bunch and a padded pouch, in a wide size run. Best if you want proven feedback over brand name.
• Cocksox Low Rise Bulge Pouch Bikini — no padding, but a sculpted pouch in a stretchy Supplex/Lycra blend; pick it if you want enhancement without bulk.
• Woof Prism Bulge Boost — the fun, print-forward option for pool days where you want to be noticed.
• M80 Tan Through Enhancing Pouch — the pick for tan lines and the widest size range, XXS to XXXL.
• JOCKMAIL Hot Spring Brief — removable pouch insert, so you can dial the effect up or down.

Skip the plain classic/mini briefs and the underwear-style thong if padding is the point — they don't have it.
