### ⭐⭐⭐⭐⭐ Fine pair of trunks
*by N***Y on 31 July 2025*

Good quality, bought for my husband as husband old pair was getting thin, and a bit risqué in public!! Fit him well and he says they are comfortable. He refuses to wear swim shorts and prefers budgie smugglers. Got him a pair of black and a pair of blue.

### ⭐⭐⭐⭐ Nice but...
*by S***N on 15 January 2025*

These are nice but not as good as the previous ones we've purchased. The lining at the front is not full frontal so this is a little concerning as they are kind of see-through when wet. If you're kinda big it may not hide everything.
