Some folks ice fish in a shack.I'm sure that's wonderful.Wyoming,Colorado,Montana has wind.I have literally watched collapse fabric shacks full of screaming people blow across the lake.
We generally travel light and sit on a bucket.
I have been camped out on Canyon Ferry Res in Montana when the catalytic heaters went dim,then out.The propane tanks were still full.We kept fishing.
Yes,all your blood flows through your head and neck.Its a radiator.
Maintain your core temp.You get a little cold,you body constricts peripheral blood flow.Hands and feet get cold.Legs get cold? feet get cold.Insulate the pipes
I would not hunt dressed this way,but feet? The old air force dry cold muklucls with three 3/8 thick felt insoles(OEM)The felt liners for those boots,pus wool sox.
The brown polar weight GI polypro long johns are good. Two pair.A pair of non waterproof nylon wind pants over those.Jogging pants.Thats a "strip down to" level for driving,a restaurant,etc.
Then the German Army heavy wool pants.
Add Carhart or Duluth suspenders.
Up top,layers polypro and polartec.
Then,insulated Carhart bibs.
Another polartec jacket,the poncho liner type GI fishtailparks liner. For reserve,a down or poly puffy vest.Then an oversize Carhart "active" jacket.The shorte hoodie version.
Over that,on top,windproof GI goretex fishtailpark (Developmental test prototype)
On my head,the grey wool Woolritch Balcava worn over a brimmed railroad cap.Hoods workover that.
Hands,the half finger wool gloves with rbber polka-dots.The chemical warmer inside,on the palm.
