>>231853Yeah, you kinda need all of that shit.
A fire, I don't think is going to matter, reflecting or not when it gets really cold, if it starts to matter it means your tent is going to melt. Maybe this is good for slightly chilly nights out in the desert or something, but not out in the snow and wind.
Insulation and extra ground-sheets, tarps, blankets, ect. Don't expect to be too comfortable, wear your thermals when you go sleep too. I'll wear everything, coat and all in my sleeping bag when it gets really cold.
When it's like, -20F and below you really need a tent with a chimney pipe and a pot-belly stove inside, because no matter how much shit you wear, some bare skin will be exposed to the chill inside your tent and will kill you, pretty much and you'll not have any fun like that.
