I agree with KenK. I try to carry everything in my pockets, without letting it get out of hand. I work in an office environment, so cargo pants with each pocket fully loaded doesn't exactly cut it.

In the winter here in Utah, I carry a Heat Sheets blanket and a cheap poncho in two of my coat pockets and take my coat everywhere I go. I have gloves and a stocking cap, in the other pocket. Weather-proof shoes/boots are worn all the winter long. I try to buy stylish AND functional clothing--I don't stand out, but I have what I need when I need it. If a coat doesn't have 4 pockets, it probably won't fit my needs. Same with pants as well. Fleece vests are great in the winter and give 2 more pockets.

I can't tell you how many times I've heard, "If I thought we were going to be out this long in the cold, I'd have brought [insert preparedness gear here] too!"
