What is the difference between a single layer, a double -layer and a three -layer Tent.

The Tent is an essential thing for the wild Camping. It can not only prevent wind, rainproof, mosquito prevention, but also keep warm. It is divided into three different structures: single, double and three -layer.Structure Tent.

Single -layer Tent

Single -layer Tent production technology is relatively simple, and its biggest feature is light, economical, and small.

Double Tent

Double -layer is different from a single layer. It adds a layer of breathable internal account to design.In a relatively cool season, the hot air excluded by the human body will condense water droplets on the inner wall of the Tent under the influence of air outside the Tent. If it is a single Tent, the water droplets will flow down the inner wall of the Tent and wet the sleeping bag.After the internal account is added, the external account will not be connected directly with the inner account. At this time, the heat emitted by the human body will pass through the inner account, so that the water droplets condensed on the foreign account will flow into the ground.The problem of water cutting.

Three -layer Tent

The design of the three -layer Tent is to add a layer of cotton account to the inner Tent, which further enhances the warmth effect.Even if the Outdoor environment is about minus 10 degrees, because of the protection of the cotton account, the temperature in the account can remain around zero, so that the temperature in the Tent is not too low.

Therefore, when the ambient temperature is above 5 C, it is more suitable for using a single -layer Tent. When the ambient temperature is lower than 5 C, it is best to use a double or three -layer Tent to prevent water from the inner wall of the Tent and avoid frostbite.
