My regular day was: Feet: boots over heavy socks over lighter socks
Legs: pants over thermals and sometime a layer of sweatpants in between
Main body: hooded canvas coat over heavy sweatshirt over long sleeve shirt over thermal shirt over T-shirt. alternating layers tucked into pant layers
Head: jacket hood over sweatshirt hood over heavy winter hat.
Hands: usually bare for the work I was doing, but when I could, I put them in some fantastic mittens my brother gave me that have been nicknamed “bear vaginas”.
If I got too warm, I could shed upper layers pretty easily to regulate temp, but rarely did I ever need to do more than lose the coat and sweatshirt.
