I need to transport 10 beers an hour away they are already cold so i need to keep them cold. My materials include a backpack, tin foil, ice garbage bags ,little plastic baggies, and a knife how can i use these to transport them and keep cold?
if i put everything in a winter jacket will that help?

Newspaper is very good for such things. I have transported frozen things this way many times. None of the above. Sorry.
