There are 2 different ones sold..
The first is basically just the same as a frogg togg just smaller and with a disney print on it.
The second is the frosty towel which is a small washcloth with citrus acid, some oils and stuff on it. You can actually buy frosty towels for 60% less if you get them direct from the company and they offer a golf towel size so just google for them.. I find 1 towel lasts about 7 days for 1 person if you carefully and lightly rinse it to keep it clean when you get back to your hotel. it's a real wash cloth so I just toss it in when I run a load with bleach and put it into the rag pile. Now I also find if your starting to get sun burnt but don't show it or feel it yet, this will very quickly tell you that your starting to bake and not always a fun feeling. you want to be ready with suntan lotion to put back on shortly after using it.
i like the frosty towels as they are about the size of a small wallet in your pocket and you don't need water around so they work great when cleaning up a little in a line your waiting in anyway.
