I will add that they work nicely with my heater body suit; very comfortable and without the bulk like other outerwear. But alone they are not as warm as traditional insulated clothing. IMOI'm not to impressed with the set I bought at Cabela's last fall. (H4?)
Their design is to be thin and "reflect" your body heat back at you, but they are not near as warm as wool or thinsulate.
I wish I would have bought the extreme stand hunter stuff instead.
On a 30 degree day it might keep a guy in the stand, but after that.....................
I'm not trying to bash them, just my personal experience.
I like to be comfortable all day, not just 4-5 hours.....You must be really sensitive to cold if you use arctic shield and heater body suit. Jesus! In absolutely no way are traditional insulated anything even close to as warm as arctic shield. Point of arctic shield is to wear less layers thus being less bulky.
