Why Fishnets in a Sleeping Bag?

From John Rambo, 1 day ago...

I used your center zip military bag with a bivy and a 2 inch thermarest under a tarp down to thirty degrees. I had a layer of wool thermals, socks and a beanie and froze. I was extremely cold and had to put more layers on and over me. Any ideas or do I need a warmer bag? I thought the bag was good down to 25°. Thanks.

I received the above e mail in the comments area of the last video.

I told John that the problem he created for himself was the fact that he was wearing wool thermal underwear because all they did was to absorb the moisture leaving his body and therefore the moisture now in the wool was drawing heat from him at a very fast rate.

The faster you lose the heat that your body is producing the faster your metabolic rate, the digesting of your food, which is your fuel. Once it is gone just like no more fuel for any furnace you start to get cold. The fact that the underwear has absorbed the moisture means increased heat lose.

Over the years that I have been selling sleeping bags I have learned a great many people wear various types of clothing in their sleeping bags. My advice is and has always been “ wear fishnets!”

Therefore, on the website there is a discount of 20% for the fishnets for all people who purchase a sleeping bag.

I have personally worn mine hunting at 12,000' in November for years with temperatures as low as -30° F so I know how well they perform as sleeping clothing.

They will always make other sleeping bags work better, but never as well as a Wiggy's bag. Wiggy bags are known to not stop the moist vapor from leaving the bag and with the addition of fishnets the moist vapor will leave even more quickly..

Sleep well in Wiggy’s.
