I'm looking for clothes that could be worn on a backpacking trip in elk country. I'm hunting in mid October so temps should be in the 30s at night time and 50s during the day. I'm anticipating doing a great deal of walking. I'm new to this so any advice would be appreciated. I'm not set on a budget right now so if you give me a cheap and expensive option or even a low middle and high price range I would appreciate it. Specific brands are encouraged.
