Great quality item and even better value as it was in the sale. Speedo swimming trunks always look good and fit well.

Good quality briefs bought for a holiday in France because you are not allowed to wear trunks in the swimming pools. Had bought the same previously but managed to lose them.

A lot tighter than I expected! I appreciate they're speedos and I like to wear this type on holiday but go for a size or two bigger if you don't want to look like you wore them when you were smaller!
