This winter, I will be working outside. Being a native of a much warmer climate, I don't understand the concept of "layers." I was told that the gore tex stuff is good if you wear layers in the deep of winter. Keeps you insulated and dry. One problem: It's really expensive! Any advice on how to keep warm without breaking the bank? To add: I work security, so all my gear will need to be dark blue/black and professional looking, as far as in a patrol capacity. Also, seeing as how I am going to be in a heated vehicle the majority of the time, what is the best way to get warm when I need it, and stay cool in truck on patrol? Again, I have no concept of what it means to be really cold. My last patrol job in California, I did experience cold weather, but we had specific uniforms to wear without the benefit of being allowed to dress for the cold. I found myself either far too warm (long johns under BDUs and Polo shirt with a zip out fleece liner and a windbreaker) or absolutely freezing without the long johns... Never found a good balance, as our cold weather never lasted very long.
