I like them a lot, years ago i had to work & visit parts of Asia where it was very hot about 40c during the day, in the afternoons i would take free time & work on my tan, i would wear my black speedo slips by the pool, they always gave me an awesome tan line, normally i am very light olive skinned but after a few hours every day in this heat my body would get a very dark golden bronze colour, the reason i always chose these slips was because when i got back to Europe, when i would be wearing a jockstrap, it was the perfect tan line.
