THIS is the key right here. Works spectacularly wolf hunting for hours long sits in very cold temperatures.If going to sit for a long time, arctic shield booties. a hot hand on the outside of the laces/toe of your hiking boots and then arctic boot over your hiking boots with the hot hand.
I went to this in single digit tree stand hunting and was the combo that actually allowed me to stay for hours. The artic shield booty things don’t weigh much and could easily be packed.
