The other gear you purchase or use is dependant upon the temperatures and weather conditions that you are hunting in.I would recommend that you or anyone else think in terms of a layering system.The mountain climbers have it all over us in terms of their under standing of how to dress and layer.
I took me a lot of years and dollars wasted before I have come to conclusions that make sense to me.If you were to tell me what conditions or range of conditions you will be hunting in I will give you my opinions as to effective ways to go about your clothing selections.
