Outdoor Tents
I'D GUESS that 99 percent of tents are
outdoor tents, after all the prime purpose of a tent is to
provide its occupants with shelter from inclement weather.
That's what camping is all about, whether it be for recreation
or purely for survival.
The rest are camping tents of one sort or another. Simple or
complicated. They are all cloth or synthetic shelters supported
by trees, tent poles and guys, or spread over a frame of metal
or fiberglass poles.
Early tents were sewn in simple designs, such
as tarpaulins (camp tarps), pup tents or A-tents. A
better design are the squared, box-shaped tents (wall
tents) with a sloping roof to prevent rain from pooling on
top. There are also or pyramid or teepee shaped shelters.
But with computer aided design of the 21st century, more
efficient designs like dome and tunnel tents have proved
to be lighter and compact to carry, yet spacious on the
inside.
The old fashioned square-ish tent, made out of cotton canvas
material, could 'breathe' naturally. There was enough space
between the threads of the cloth to allow moisture in the air
to escape outside. Modern tents made of nylon and other
synthetic stuff can be too watertight for the moisture vapor to
escape, so better ventilation must be designed in.
Most of these modern cloth tents also have insect netting on
the doors and are engineered to promote a comfortable air flow
inside. The camping tent can be adjusted to allow warm air to
escape in hot weather, while in cold weather, the air flow can
be restricted to minimize condensation inside the tent while
still keeping some heat within.
The best tent systems have an outer shell or fly sheet to
keep out the weather. A breathable inner tent attaches on the
inside, and that keeps annoying insects like gnats and
mosquitoes from getting at you while you sleep. In some parts
of the world, such insect screens can help save you from
malaria or other insect-borne diseases.
All modern tents have a waterproof tent floor built in to
them. This makes the ancient ground sheet redundant. However an
optional ground cloth spread inside your tent can catch the mud
off your shoes and other debris that falls off your clothing.
Then, when it's time to break camp, your ground cloth gets
taken outside and the dirt shaken out. The tent can be rolled
up nice and clean, and be packed away without the need to sweep
it out first.
Incidentally, the only tent I can think of which isn't
an outdoor tent, would be a photographer's light tent. It's a
system of white cloth or other diffusers, built to surround an
object with light from the top, all sides and sometimes below
as well. It lets you take a photo with no shadows showing at
all. It's pretty specialized stuff, and I know about it purely
because photography was my first trade and profession.
