Winter camping requires proper clothing, shelter, sleeping systems, and cooking equipment to stay warm and comfortable. For clothing, it is important to wear layers and avoid getting wet. Tents provide good shelter from wind and snow, but snow caves and walls can also be used. Down or synthetic sleeping bags rated for cold temperatures, along with insulated sleeping pads, keep campers warm at night. Canister or liquid fuel stoves are suitable for melting snow and heating prepared foods during winter trips.
