In all seriousness these things are available everywhere. Unless you live in the most undeveloped area of Montana you should be able to pick one up in anyone of 10 stores in the city you live in. Wal-Mart, Wallgreens, CVS, Rite Aid, Eckard, and many more.
But what I thinks works even better is to make your own. Simply mix 1 part rubbing alcohol with 3 parts water in a zip lock bag and put it in the freezer. This will make a very cold slushy that forms to your body better than most ice packs.
yo cp seriously there has to be another name than cold pack
You know who was manufacturer anything?
