Everyone knows what a tent is, of course: a collapsible shelter of fabric stretched over and sustained by poles. This definition is fine, as far as it goes, but tents designed for different functions differ greatly in features. A military tent, for instance, differs considerably from a recreational tent.

. For most people, when they think of a tent, it is this latter image that springs to mind. Such tents are usually made of nylon or polyester, a vast improvement over the"waterproof" cotton that was used until comparatively recently. Recreational tents can sleep anywhere from one person to nine individuals, sometimes more. The frames are usually aluminum, steel or fiberglass.
Most modern tents actually have two layers of fabric. The outer layer is waterproof and is called a flysheet or rain fly. This layer is suspended above and away from the tent's inner coating: this type of set up allows condensation to accumulate on the inside of the flysheet without danger to the inner tent. The inner tent is not usually waterproof, as the use of the flysheet prevents this necessity. However, there are some tents that use only 1 layer, and for these a waterproof and breathable material is utilized. Such a substance prevents liquid water from penetrating the tent while allowing water vapor to pass outside.
