because it is a cold material
I think it's an insulator
Tin is a good heat conductor. So to keep hot water in a tin can hot you need to insulate the outside and bottom of the can with something that does not absorb heat but instead contains it next to the can.
Not a requirement, but a very good idea if you plan on keeping it for a while.
Foil itself will not warm it, it has to already be warm for it to insulate it.
Both Good for keeping you warm; Bad for the environment
cotton is very good because it warms up your body others are too hard or not very helpful however, metal is good to because when you put tea or coffee in the metal cup it heats up and keeps you warm.

The first successful trip to the south pole (and back) was made by Roald Amundsen. He and his team wore anorak's (or parkas) which is not only good for keeping warm, but also keeps the cold winds from reaching your skin. Although it is common knowledge that wool is good for keeping you warm, this material is way to light, and give very limited protection against heavy winds.Anoraks are heavy clothing made by fur, which also were used by Inuits.
