First Layer
The 1 st layer (underwear), aims to keep the skin dry by expelling the
sweat away from it and avoid being chilled (wet clothes Skin contact can let heat escape
twenty-five times faster than dry).
The choice of this first layer is crucial for optimal functioning
outerwear. As if it were a second skin
should match throughout the body, neck, wrists and ankles
, to trap warm air generated by our body avoiding
you move abroad. However, be careful not to squeeze in
excess and slow the flow of blood.
This type of garments are made with stretch fabrics and
no side seams. The fewer seams are flat with
greater comfort. If you make the mistake of using this type of clothing
conjunction with conventional cotton underwear, we will cancel the benefits of
these materials, since cotton will absorb all moisture and keep in contact with skin
. According
Light
thickness is the thinnest (Duofold ™ 375-SS, 360/361-PB, 370 BX, 700-LS-LD and The North Face ™
Aerobic), ideal for cold areas where it exercises intense physical activity and produces
a lot of sweat, helping to perspire and expel the sweat. Average thickness
(O-LS-LD Duofold ™ 51, 760-ZT, 761-LS/MU-LD/MU and The North Face ™ Alpine), ideal for cold
continuing operations increased thickness
issue is the thicker (820-Py Duofold ™ The North Face Expedition), used for activities
more static with minimal sweating. This is the type most calorific. Can be reached
used as replacement of a 2 nd 1 st layer on a thick layer of light.

S econd layer
As we have seen, the function of the fibers of the fleece,
as a second layer, is to retain the heat generated by the body
isolating the cold outside.
tissue becomes Polyester fleece by applying a treatment of partial tear of the tissue
using small gears: the threads
open in micro-filaments in a vertical position giving
spongy and soft. This will get moisture resistance, fast drying
calorific value twice that offered by the wool,
creating a warm and dry insulation around the body, the
moisture away perspiration from the skin. No rot and just absorbs odors. Its main drawback
is that the wind gets pass it, causing the
problem of heat loss. To avoid this, have created new materials such as rolled
the Windstopper or Windbloc.
Models with reinforcements in the crucial areas specifically designed for
climbing or carrying heavy backpacks.
As the first layer, the feature to be considered for the election of the first
layer is its thickness. There are three types of weights: Light
Average thickness Thickness
expedition garments made with windproof membrane, such as the Windstopper ® or
the Windbloc ®, are considered of medium thickness. It is not normal to find them in thick
issue, since in these cases is combined with a fleece outer garment
3 rd layer perform the function of short wind.
Third layer
Recall that the third layer should protect against wind and water
while allowing breathability.
A careful preparation of the third layer
should allow optimal mobility, protecting outsiders even to stay in position or posture
trickier. For example, let the best hoods
Helmets hold under them, have
Bourkes and follow the movement of the head to provide a total view
even looking back.
In the third layer must take into account the following factors:
1. The number of layers is that this third layer.
2. Impermeability.
3. Breathability.
Depending on the fabrics used for laminating or induced
features breathable, waterproof and will vary significantly. Thus, according to different
trademarks, we can find various materials.
Other systems
The down
We have seen that the retention of body heat can be obtained from the air chambers that are among the body
and abroad. On this basis, against more air chambers
appear in less space, more heat retention is achieved. The pen of its merits, is the fiber
more air gets cameras, as well as expand and compress the fiber
better. Moreover, it occupies less space when compressed within a sheath
and equal benefits, weighs less.
The drawback is that it is more delicate than synthetics and there
to avoid getting wet, which is why their linings are usually of nylon, not cotton because the cotton absorbs moisture
. Nor can it be washed often as in the case of fibers and
should be done with special products. Otherwise, the pen cakes and holes are created within the chambers of the garment
.
There are different qualities of pen and classification from highest to lowest heat retention is:
duvet, the down and crushed the boom. The duvet will be with us to notice the least touch of the cane,
therefore is that we get more heat retention. Garrido
