A SIGNIFICANT BENEFIT DERIVED FROM FISHNETS
The other day when answering a question for a new customer about the fishnets and how they work I realized that there is one significant benefit I have not covered.
Trapping the radiant heat produced by the human body!
The core temperature of the human body is 98.6 degrees. The skin surface is 91 degrees. The heat from the core moves to the skin cooling the core which is natural and it happens faster the more active you are. The heat produced must go someplace. The method by which the heat leaves the skin surface is called radiant heat loss. There is also heat loss when the vapors come out of the pores which are also warm, which is called evaporative heat loss. If the moisture is stopped from freely moving away from the skin surface it will condense on the skin surface and in cold conditions that leads to a chill. When you wear fishnets the moist vapor freely moves away from the skin so it does not condense which would cause the chill. This too is part of the evaporative heat loss process.
What I have neglected to mention is that the radiant heat emanating off of the skin surface can only move as far as the next layer of material surrounding your torso. People who start dressing by wearing the fishnets as their first layer and specifically a cotton or wool second layer discover that they have a layer of warm air now trapped between second layer and your skin surface.
Cotton and wool are very poor conductors of heat. When the radiant heat reaches either of these fabrics they absorb the heat but do not pass it on to whatever the third layer of clothing is. Therefore, the heat is trapped so it can keep the moisture in its vapor state which is free to move through the spaces between the yarns that make up the fabric. If you wear any of the knitted polyester garments as a second layer you will lose much of the heat because the synthetic fabric does react quickly to heat and is an excellent conductor of heat. The end result is the fact that the moisture will condense. Once condensed, it now will be trapped in the garment, and that same moisture will also conduct heat away from you. Moisture is the best conductor of heat on the planet. Knit fabrics will also restrict your movement versus a loose fitting shirt made from woven fabric. I speak from personal experience when I was lost in the blizzard. The story can be read on the web site.
The reality of dressing for the cold is to, as much as possible help, or allows your body to do what it has to so you stay comfortable naturally. I do not believe for one second anyone who is employed at or is the owner of any company that is marketing base layers made from synthetic yarns and are knit fabrics has ever bothered to use these garments in a layering system. If they did they would have discovered that their garment matter of fact retains ALL of the moisture they created. They probably know that but they sell their garments on the basis of being in a single layer in the summer sunshine when it means nothing.
Those companies that sell wool base layers are either stupid or uneducated about wool fiber, here is a secret for you to know; “WOOL LIKE COTTON, SILK OR RAYON DOES ABSORB MOISTURE”, so as a base layer against your skin what comes out of your pores as vapor converts to liquid and stays in the fabric; PERIOD!!!!!
I have been told by mountaineers that they get a chill every night they are in their tents and guess why, they are wearing polyester or possibly wool or silk base layers. This holds true for the Everest climbers as well.
It all boils down to one garment and one garment that one should wear as a base layer in cold conditions and I mean when the temperature is 40 degrees above 0 F and lower and that is FISHNETS. When you are out in the field for several days at a time you do want to be comfortable and getting a chill at the end of a day is not comfortable and it will very easily compromise your ability to fall asleep. People who are cold DO NOT SLEEP.. But when you wear fishnets you stay comfortable because suddenly you realize you did not get a chill.
FIRE RETARDANT SLEEPING BAGS
For the past two years I have been asked about my use of flame retardant on the materiuals of my sleeping bags.
I Jerry Wigutow do not now, never have or ever will make a sleeping bag that has any flame retardant chemical applied to the materials; PERIOD!!!!
I do hope this puts an end to me being asked the question.
