is a protective covering
like a bag for a person to sleep in, comparable to a bed and
blanket. The main idea behind a sleeping bag is to provide
warmth and insulation. To a certain extent sleeping bag gives
protection against wind, precipitation, and exposure to view.
But as such you cannot use it in place of tent. To sleep on
a sleeping pad is used as the sleeping bag does not provide
ample cushioning. A bivouac sack is a waterproof cover for
a sleeping bag and can be used in place of a tent for lightweight
travelers or as a backup if stormy weather occurs.
basic bed bags
is simply a
square blanket, with a zip stitched on three sides so that
it can be folded in half and secured. A sleeping bag of this
type is packed by being folded in half or thirds, rolled up,
and bound with straps or cords. The basic design works well
for most camping needs, but is not enough under more demanding
second major type of sleeping bag, sometimes called a mummy
bag due to its shape, is different in a number of important
decreases from the head end to the foot end so that it reduces
its volume and surface area, and improves its overall heat
preservation properties. A few of the bags are designed in
such a way so as to accommodate women's body shapes.
generally does not unzip all the way to the feet. The zipper
is ineffectual in any sleeping bag's insulating qualities.
Together with the tapered shape, this feature of this design
helps protect the feet, which are more susceptible to heat
loss than other parts of the body. It generally has a drawstring
at the head side so as to help avoid the escape of warm air.
But packing a mummy bag will not be so easy, as a mummy bag
generally cannot be rolled like a rectangular bag. Instead,
it is simply kept in a stuff sack or compression sack.
should be filled with
such a material that it is not too heavy and so different
insulating materials are available for bed bags. Enthusiastic
outdoorsmen usually prefer synthetic fill or down.
fill does not absorb water, dries easily, and provides some
if it is thoroughly soaked. These characteristics may become
very convenient if the sleeping bag is accidentally dropped
into water on a cold day. Synthetic material is firm and resilient
and insulates well even beneath a person's weight. Synthetic
Fibers have the ability to loft faster than down which allows
the bag to provide the insulation faster than a down bag.
weight of down fill is less than synthetic fill and it also
retains heat better, but is more expensive. Down
is useless if wet so should always be kept in a dry place
as a soaked down sleeping bag may provide even less insulation
than no sleeping bag at all, leading to hypothermia. Now the
modern technically advanced bed bags often have water-resistant
shells, so they can be used in damper conditions.
materials like cotton and wool have also been made use of
for bed bags. Wool has the qualities of repelling water as
it is naturally greasy and also resists compression, but the
weight is the negative factor of wool. Cotton has the drawback
of high water retention and considerable weight, but its low
cost makes it a desirable option for uses like stationary
camping where, these matters are of little consequence.

should be made of
the world's pre-eminent synthetic insulation, to keep you
warm in the most frigid and wet conditions on earth. If you
are not worried about the weight of the sleeping bag but are
worried about only wet, freezing weather condition you should
choose your bag wisely. Overlapping shingle construction prevents
cold spots from developing even after years of use. A soft,
breathable silken lining feels nice to the touch and aids
in heat transfer should it become a little too warm. A few
of the newer bed bags offer larger alarm pocket with plenty
of room for today's over-sized altimeter watches. A draft
collar and full-length draft tube seal precious warmth in,
while color-coded pull cords make for easy hood and chest
adjustments. Generally they come with Nylon or mesh storage
bag and stuff sack.
modern bed bags keep you warm and comfortable down to 20ºF
and a few of them weigh It makes them an excellent choice
for cold weather camping. Nylon provides even construction
for a more down proof fabric which makes sense that it is
not likely to leak out of the bag. A silky smooth taffeta
lining is soft on the skin and breathable for climate control
inside the bag so you stay warm. A new design of the bags
has unique split collar, which combines half of a down filled
tube with flat fabric and cinches down to seal in heat as
effectively as a full draft collar but without the excess
new design of synthetic bag ideal for expeditions in damp,
sub-zero temperatures. In this bag you can sleep while resting
your head on the built in pillow pocket you can stuff with
clothes. A head level alarm clock pocket will not let you
sleep late. A modern design of sleeping bag uses A-Flex construction
to keep warm air from escaping and moisture from intruding.
The fibers are silver treated and anti-microbial keeping your
bag stink-free even if you sleep for many nights in it. Many
other features like pillow, heater, and stash pockets and
a draft tube are therein the bag. There are many bags, which
are just perfect for summer surf trips, backpacking, and humid
climates, which uses new type of insulation to keep protection
from moisture while keeping you warm. There are many new advantages
like getting stuff sack free and also a nylon mesh bag for
long term storage, which helps preserve the insulation's loft.
Generally all of them have features like t one-hand, color-coded
pull cords to adjust the hood and easy-grab pull-tabs on the
zipper. So enjoy camping.
