I am a 21year fire fighter, I live in Louisiana and it gets very hot here, as it does in a lot of other places. I ran across a new product and had to try it out. it is a cooling pac that i wear under my turn out coat,It has 4 cold pacs, and is very comfortable to wear.It stays cold around 2 hours before I have to change out the cool pacs.

Has anyone else used something like this? and what do you think of them?

If anyone would like imformation on them please let me know.
