Tents are rated for the seasonal conditions they’re built to endure. Three-season models are designed for Spring, Summer, and Fall, and tend to be the most popular style. They’re also lightweight and built to withstand windy and rainy conditions, but not snow. That’s where you’ll want a four-season tent, which is designed to withstand year-round conditions with the help of additional poles that strengthen the tent’s walls. Four-season tents also have less mesh, which allows them to retain more warmth.
