Four Season Tents
Four-Season Tents refer to tents that can be used year-round and specifically during the winter months. The main difference between 3-Season tents and 4-Season tents is the ability of the given tent to withstand high wind, snowfall and colder temperatures.
4-Season tents are constructed with heavy snowfall and wind in mind. Typically, these tents are built using stronger more durable fabric. The poles are stronger and more rigid and fabric is more durable. Many of these tents are designed with steep angled sides which help shed snow. It is also common for these tents to come with extra external poles to further reinforce the tent structure. These tents usually have a higher strength waterproofing, stitching, and hard gear (zippers, etc.)
Unlike 3-season tents, 4-season tents do not usually use mesh. Instead, solid material is used in both the inner tent and fly. Solid material is a better insulator than mesh and does a better job of keeping rain and snow out of the inner compartment.
Four season tents also tend to have two openings and vestibules. With heavy fabric and lacking mesh, these tents do not vent like their 3-season counterparts. Designers of 4-season tents have this in mind when they use multiple doors and vestibules. Multiple doors can create much needed airflow in mild weather. Vestibules also serve as a halfway point to remove snow from your clothing and boots before entering the main tent compartment. In very severe weather, vestibules can also serve as a sheltered kitchen to cook in (with caution.)
Four season tents should also be easy to set up in variable conditions. These tents can be found in bright colors that make finding their location easy in snowfields.
