There are only two reasons why anyone would sleep outside in the dead of winter.
You’re either a hard-core adventurist or a survivalist (or both).
And when the winter months come along camping changes for the colder.
For every inch of snow and for every degree colder it gets, sleeping outside becomes more dangerous.
That’s why winter camping requires special gear.
And the most critical piece of winter equipment to invest in is a high-quality cold weather tent.
