If you want to hunt in very cold temperatures, you will benefit greatly from choosing hunting apparel with insulation. Padding or insulation is designed to keep you warm. It is important that you are able to maintain a stable body temperature throughout the day so that you don’t freeze.
Wool is warmer than synthetic fabrics – whether it’s wet or dry. Wool wicks moisture much more effectively than cotton, but not quite as well as synthetic fabrics. Wool also takes considerably longer to dry than synthetics.
