If your outerwear is sufficiently insulated the midweight should be fine , the weather report will determine whether or not you should add or subtract . Wool would be my choice for an outer layer with poly if temps are very low , fleece if more temperate . Considering how cold your state can get in Fall and Winter , wool is the best all around choice if you have a first layer to avoid itching . AbScent makes undergarments that block our smell too , you might want to check them out .

You can layer your wool socks if your boots don' t have enough insulation , my choice would be a poly sock for wicking , or a nylon/aluminized mylar sock . Alternatively , you could try insulated overboots .

Our Indiana Winter temps may be lower than yours , but I' m a world class wuss when it comes to being cold !
