ABOUT LAMILITE INSULATION AND WIGGY BRAND
Lamilite insulation is what sets Wiggy brand sleeping bags apart
from all other brands.
What is Lamilite and why does it perform better than all other forms of insulation;
natural (down, wool, etc.) or synthetic?
Lamilite is synthetic, polyester fiber. When polyester fiber
was developed it was produced in various thicknesses referred to as denier.
Fiber denier varies from a thin ¼ denier and thicker, such as 15 to
20 denier used for making carpet. The ideal denier developed for insulation
became a 5.5 denier. Lamilite is made from a 5.5 denier continuous filament
fiber which has been coated with a silicone finish vs. chopped staple fiber.
The difference being how the fiber is utilized in the manufacturing process
employed to make sleeping bags or any insulated product for that matter.
Chopped staple fiber must be sectioned off with quilt stitching or it will
break apart when laundered. The problem worsens if the fiber has a silicone
finish; it will move more quickly during the laundering process since it
has a slickened surface developing un-insulated areas (cold spots) during
the laundering process.
None of the above is possible when
continuous filament is used. Lamilite continuous filament fiber is first
adhered to the shell or lining material to stabilize it for manufacturing.
It is then cut in large sections for each layer of the sleeping bag. The
next step is to perimeter sew each section to further stabilize the fiber.
There are no quilt stitches involved in this manufacturing procedure; quilting
will cause the fiber to fatigue and ultimately collapse there by reducing
it insulating ability. The next step in the manufacturing procedure is to
attach each component at the perimeter of so as not to diminish any area
of the bag compromising the insulation. This manufacturing method allows
for lighter weight sleeping bags for all temperature ratings. Lamilite
bags are not adversely affected by moisture the way all other bags are; i.e.
absorb moisture and collapse losing 100 percent of their insulation capability.
As a point of fact Lamilite has shown that if a man who is completely soaked
is placed in a Wiggy’s bag in a matter
of a few minutes he will notice that he is warming. After a few hours not only
is he dry but his clothing if worn or simply placed in the bag with him will
show definite signs of drying. Many people refer to the movement of moisture
in situations of this nature as wicking of the moisture. That description or
definition is in accurate. Wicking is when moisture moves with in a material;
such as oil moving up a cotton wick in an oil lantern. If all the materials
are synthetic wicking cannot occur, therefore what we see is evaporation generated
by the heat produced by the man in the sleeping bag. This form of drying has
never been shown to happen in any other sleeping bag using any other form of
synthetic insulation, and of course is impossible to happen when down is the
Lamilite gives Wiggy brand sleeping bags another
advantage; its launder-ability. Historically manufacturers of sleeping bags
have dissuaded their customers from laundering the bags they sell because they
the manufactures know that laundering the bags is detrimental to their construction;
refer to paragraph two. That is simply not the case with Wiggy’s brand
sleeping bags. Wiggy’s brand sleeping bags can be laundered countless
times. They can be laundered in any washing machine; home or commercial without
damage. Actually it is in the best interest of the user of a Wiggy’s
brand bag to wash it when ever convenient. The reason to launder a Wiggy’s
brand bag is plural. One the bag gets clean; two the fibers stay lofty and
three some of the may fibers do not get separated during the manufacture of
the Lamilite and the tumbling action of the drier will cause more of the fiber
to separate therefore causing an increase in the loft of the bag.
Last but by no means least Wiggy brand sleeping bags
are the only bags purchased by the U.S. military; all branches; that are vacuum
packed under approximately 23 tons of pressure and blister packaged for survival
kits. The Air Force uses them in their fighters and transports. The Navy uses
them on all 4 and 12 man survival rafts. The Army has them on aircraft and
helicopters and the Marines on transports. Wiggy’s brand sleeping bags
or rather Lamilite insulated sleeping bags are the only sleeping bags made
in the world that can fully recover their loft; i.e. insulation property once
broken out of the blister packaging.
The Ultima Thule model is rated by the U.S. military
for temperatures as low as -35/40 degrees F. This rating was established by
the U.S. Navy. This bag carries the following designation –WIG20UL and
Wiggy’s Inc. at present is the single largest
supplier of sleeping bags to the armed forces of the U.S.A., and has received
recognition for service and quality of our products from the U.S. Navy. We
were awarded “Blue Ribbon” status.
