True temperature rating
I took my superlight out on a new year’s camping trip with my dad onto some mountains in Tennessee, the temp that night got down to about 1F before wind-chill. I was fine in this bag and having a matching poncho liner made it much more comfortable. Me being a powerlifter at about 6"0 and 236lbs this bag in the wide sizing fits very well. I also never go out camping without the Wiggy’s pillow that was included, by far that is the best camp pillow I've ever used. This is a superior bag and rivals the USGI bag combo that is currently issued. The material is extremely durable and comfortable to sleep in; I recommend this bag highly to anyone on the fence about it.

PHYSICS AND RAINWEAR
PHYSICS; PHYSICAL PROPERTIES OF BEHAVIOR, THERE ARE MORE DEFINITIONS BUT THIS ONE RELATES TO THE ARTICLE TO FOLLOW.
RAINWEAR; WATERPROOF OR WATER REPELLENT CLOTHING
The purpose of rainwear is to protect a person from getting wet from the rain.
For thousands of years (since 1900 BC) people have made garments to protect them from rain. They used woven grasses, seal intestines, rubber applied to fabric, oils such as linseed oil was used to saturate cotton. Charles Macintosh coated cotton with rubber in 1836.
In doing my research I read that all of these materials did keep the rain from getting inside the garments but also these same garments kept the sweat inside the garment. This is the same actions that we experience today with “modern day” rainwear.
Therefore, the problem is not how to keep the rain out but how to get rid of the sweat, as in getting it out of the rain garment.
Physics tells us that getting the sweat out of the garment cannot be done. What can we do about this situation so we are comfortable and not wet in our rain garment? There is one garment presently available at this time which I will identify later.
Every person reading this article and every person who does not read the article has experienced the same thing when it rains and that is the drop in ambient air temperature. I became very aware of this action when I started sailing. I was sailing in Long Island Sound during the summer when temperatures were in the 80s and 90s. When a squall happened the temperature would drop very quickly 20 degrees. That being the case I had to put on a sweat shirt or sweater under my rain slicker. Both of these types of garment otherwise would not be necessary to wear on a 70/75 degree day. But in this circumstance they were necessary. My skin was wet and the moisture caused a chill.
I was still sweating although just normal versus aggressive which was building inside the rain garment. The only way to dry was to get out of the squall anchor and get into the cabin and take off the garments to dry out. Would it be different today with the rain garments available, NO!
Air at a higher temperature can hold more moisture and you will have a condition where when the air that you sweat meets a cooler surface, the air cools and is not able to hold as much moisture as it is already holding and condensation occurs on that surface, you’re skin or any other surfaces that the vapor comes in contact with. The moisture laden air otherwise known as vapor condenses because it has cooled.
If the vapor were able to reach the inside of the rain garment it would condense very quickly because the nylon fabric or any fabric will be the same temperature as the ambient air. Even if the fabric is vapor permeable it would not matter since the vapor will already have condensed on the inside of the garment. All synthetic fabrics respond very quickly to temperature changes.
Now that we understand why moisture as a vapor cannot ever get out of a rain garment we must examine what can be done to minimize the unpleasantness of the clamminess. The answer is a certain level of insulation. But if you add insulation to the garment, won’t that make you hot, no! Remember when it starts to rain the temperature drops, so some insulation is necessary.But what about when it is not raining, the level of insulation that I believe necessary would not be for arctic purposes but for 40 degrees and warmer.
The reason for the thin layer of insulation is to allow the moist vapor to move from your skin surface through the insulation so it will condense between the insulation and the inner side of the exterior of the shell material. If the fabric is vapor permeable when the rain stops and the temperature increases you will experience some of the moisture on the inside evaporating through the fabric so long as it is not coated or laminated to any film.
The only rain garment made in the world today that will keep the rain from getting into the garment for the most part and will at the same time allow sweat to move from your skin surface to the inside of the garment away from your skin is the WIGGY’S DUCKSBACK ZIPPERED JACKET! This garment is insulated with 2, 5 ounce Lamilite. This garment has already demonstrated that it performs in this manner many times since it has been on the market, so I am confident of its performance capability.
Every bit of information that has been coming forth for over 40 years now from every company that has talked of their fabric doing the impossible is nothing more than a lie. There never has been any proof of what has been claimed demonstrated by any company. Some of these companies just supply the materials and other companies are considered garment manufacturers who have created their own materials. In all cases they have demonstrated in laboratories for themselves how vapor can be pushed through the materials under pressure but they cannot demonstrate in the field the same result as seen in a laboratory.
I believe all of the owners, managers, sales personnel and every one else in the employ of these companies know that their product does not perform as advertised. You would think after 40 years these companies would have accumulated stacks of testimonials from satisfied users that they would be proud to publish. but in 40 years I have never seen any positive comment about these products, but I have certainly read a substantial number of negative comments pointing out that the materials the garments are made from with film laminated to them did not perform at all. All these company owners are concerned with is your buying product made with their material. I also believe the retailers at the highest levels of management also know the product regardless of the company name on the garment know it doesn't work, And of course the companies that make the garments also know the fabrics do not work as well. The outdoor industry has given many awards, for what screwing people out of their money by providing non-functioning garments. What is their pride of accomplishment, they have no accomplishment so they can't have pride.
You now understand why ALL of the garments you have ever purchased with a label that read’s “waterproof and breathable” has never proven to function in that manner, in essence you have been lied too. You also now know what is available that will perform for you.
This article starts off with a testimonial about the most important item of all the items you take into the field, a sleeping bag. I am very proud to publish these many testimonials that I receive, something these companies have no interest in.
