Reply to comment by odd_1nt3g3r5 in TIL Snow is an excellent insulator because it consists of about 90–95 percent trapped air (fresh). This is the reason why igloos are warmer inside than outside, and why some animals in colder regions build snow caves to spend the winter while hibernating. by SunCloud-777

Quinzees are amazing shelters and I do believe what most people mistaken think of when they hear 'igloo'. Igloos require specific snow and conditions to be able to build. Quinzees just require snow, preferably dense snow so it sticks together.

Just gotta be careful when building them. The whole idea is to have a shelter to protect against hypothermia, but if you work so hard you begin to sweat, you kinda defeat the purpose. Either requires a change of clothes or just take your time making one.

Yep, we were cautioned about sweating during training before our outing. Go slow, pay attention to your body, and remove layers (especially your hat, weirdly enough) if you get too warm. Sweat is deadly in the cold.
