I'll throw a couple things on the list for winter.
Over sized Rain gear, it should be able to be worn over your clothes, keeps you dry and can function as a wind break.
Wool is probably the only man made fiber that rules in cold weather, it's the only material that will keep you warm soaking wet.
Boots not the $180 LL Bean boots, but the $19.99 Walmart Specials they will keep you warmer then your Jimmy Choo's.
I like cans of soup, you can warm them in the car and use the empty can to melt snow for water.
I always pack extra food, odds are your aren't going to be the only one stranded.
