BEING COPIED
The greatest form of flattery is when a company that
wants to compete with you makes an effort to copy what
you have done.
A few years ago the Mountain
Hardwear Company chose to copy the Wiggy’s bags
by laminating a continuous filament fiberfill and making
a sleeping bag. I reported their effort in an article
titled “An expensive disposable sleeping bag”;
see the archives; Spring 2005. The bag line was called
Lamina and as I expected it was a failure. They then
made the bag line with a chopped staple fiberfill which
is currently being sold and I expect once they have had
their fill of returns for various reasons it will also
be dropped. Now a new company is touting their “new
technology of a laminated constructed sleeping bag”.
The company is actually quite old established as I
read on their web site in 1862. It is Mammut located in Switzerland. Their
bags are sold under the Ajungilak brand name. The following is what they have
to say; “The Future is Ajungilak’s first ever synthetic fiber sleeping
bags to have no quilting seams--the company’s synthetic MTC © 12
insulation is now spot-laminated to the inner fabric. The disadvantages of
seams-they form cold spots, add to the weight and impair the fabric-are no
longer an issue. As a result, the future benefits from a higher European EN
13537 warmth rating than a quilted bag using the same materials.” They
even show an inset of the lamination and an inset of the quilting.
The fiberfill being used in these bags as far as I
can tell from their web site is a chopped staple form of fiber. If they were
to use continuous filament fiber they would have to buy it here in the USA
since it is only made in the USA and the cost of shipping would be prohibitively
expensive. Therefore, I can only assume it is chopped staple. Under this circumstance
I expect they will have the same result as the Mountain Hardwear company will
experience; product failure. I could save a considerable amount of money if
I were to use a chopped staple fiberfill; however all of my efforts in the
1960’s to develop a laminated fiberfill product using a chopped staple
fiber ended in failure. Why these companies think they will fair better is
amazing to me to think about. But they will as I did. The fact that the
laminated bag tested better than the quilted bag is understandable; getting
rid of the quilting and having a uniform loft is always better. The bags tested
were obviously unused bags. They should test them after six months of use;
sleeping in them, stuffing them and washing them. I am sure the results would
be equal.
The EN 13537 rating system is no different than the clo
rating system; neither in my learned opinion have any
value.
But it is terrific for my ego to know a company as
old as Mammut thinks enough of what I have been doing for 40 years is good
enough for them. They have recognized the value of eliminating the quilting
and the need for laminating the fiberfill for easier manufacturing, but they
are avoiding the truly real necessary ingredient; continuous filament fiber
as the insulating medium.
So, once again I am being complimented
by a company recognizing my accomplishment and they try
to copy me. For this I am very grateful since it ultimately
gives me even more credibility in the market place.
ADDITIONAL INFORMATION
After reading what they had to say I called the company
and was given considerably more information. First off
they are definitely using a blend of chopped staple fiber
for their insulation. Again; it didn’t work for
me so it will not work for them.
One item that was sent is a
publication online titled “sleep well; temperature
ratings; a review of temperature standards for sleeping
bags”. It is interesting with respect to the history
of sleeping bags being used as early as 1890. Aside from
that aspect of the paper it is a review of how the scientific
world has attempted to correlate temperature ratings
from machines to humans. They write about the development
of the copper manikin and their EN temperature rating
system. EN is short for European Normal. An explanation
for what European Normal is is not explained. Could it
be that European people are different than we in America
physiologically? All sleeping bags sold in Europe must
meet the EN standard which was set by CEN (European Committee
for Standardization). The Treaty of Rome in 1957 saw
the establishment of the European Common Market. It was
at this time that the CEN was established to “harmonize” various
national standards and the EN became the binding standard
in all European countries. If you sell to retail stores
and your product does not meet the EN standard you can
be fined. I was told by the buyer at REI they would not
carry any sleeping bags that were not EN compatible or
certified or something of that nature. I told him I would
not be able to sell him under those circumstances since
I at the time had no knowledge of what the EN was nor
was I going to go out of my way to find out. So now I
know and I know that the EN rating system is no different
than the clo rating system. BOGUS and MEANINGLESS!!!!!!!!!!!!!
The paper goes into detail as to the differences between
men, women, children and age groups. It tells you what you should eat, keep
dry, and wear extra clothing and a myriad of other bits of information that
has little value. However they demonstrate their ignorance of synthetic insulation
and what we now know after 40 years of use in the field. Continuous filament
fiber when used in the proper construction method and adequate weights for
the desired temperature rating and totally voids any detrimental effect of
water in any of its forms. When that is in place it negates the need of extra
clothing, slows the metabolic rate so what you have eaten produces heat in
the body for a longer period of time. Their knowledge of fiberfill for insulation
is relegated to chopped staple fiber; truly a dinosaur of the industry. Of
course if one were to produce continuous filament fiber in Europe they would
change to it as their insulation immediately.
The paper also notes that their results when testing
any bag are not reproducible. Imagine that, maybe they should do as I have “put
people, humans inside the sleeping bag” and let them tell you how cold
a temperature it is good for. I have yet to meet a machine capable of doing
that that is to tell you if they are hot or cold. Human results are very reproducible.
We, each of us are not very much different physiologically. If we use as an
example young men of approximately the same age as I have; military personnel,
the results are quite accurate. After all when they are using my bag they are
all wearing the same clothing, involved in the same activity, dining on the
same food all at the same time. What I have gleaned in information is invaluable.
No machine or group of machines can equate.
I pity the European retailers as well as the consumers.
The consumer is buying a sleeping bag that has this mandatory EN rating. When
the consumer finds that the EN rating does not equate to use in the temperature “C” that
has been equated to the bag they will justifiably return it. Of course the
retailer will now have a used bag which I expect they will be able to return
to the manufacturer. When enough of the camping public has gone through this
process they may decide not to camp any more. I have come in contact with people
here in the USA that stopped camping because of faulty equipment to include
a bag that would not perform as advertised (not a Wiggy bag, sometimes they
do now order one and voila they go back to camping). I read on outdoor forums
that are frequented by tree hugger backpackers as well as hunters stating in
no uncertain terms that this brand or that brand of bag didn’t come close
to the manufacturer’s temperature rating. The primary reason the bag
was purchased in the first place was due to its light weight and compactibility
for the temperature rating. Some of the brands of bags purchased were from
European manufacturers.
At least some minor progress is being made with respect
to construction; there is a trend to laminating the fiber even though it is
the wrong fiber. I offered the original Polar Guard laminated to every manufacturer
in the USA starting in 1968 and was turned down obviously by ALL. Today there
are no employees of any of the companies still around who were with those companies
years ago who now see what I am doing and they think it is something new. As
time proceeds I expect that sooner or later ALL companies making synthetic
sleeping bags will try laminating their fiberfill. If they chose as Mountain
Hardwear and Mammut have done to go with a chopped staple they will fail. If
they were to come to me and wanted Lamilite I would be happy to sell them.
After all I do not believe I can make all of the sleeping bags sold in the
world, but I can supply all of the Lamilite that is needed.
