My shelter group definitley changes. 9 moths out of the year is my summer carry, so the clothes I wear usually consist of cargo shorts and a t-shirt. There is no rain or cold nights to worry about. In the winter I carry whatever coat, parka, or jacket is necessary for sleeping a full night outside in the cold (for me thats about 50 degrees. In the jacket I have more survival supplies, namely gloves, balacava, food, candle, extra firemaking gear, etc.
