follow up to cooling vest

Hi Jerry,

When I was in Israel, we saw Bedouins who wore layers of garments in the desert. I can't remember the correct explanation but it seems to me that the guide said that the multiple layers cooled them better, protected them from the sun and kept them from drying out. Something like that anyway. Most of them were black too!

All I know is that the first time I hiked a mile down into a canyon and back out on a hot day in July, my brand new Wiggy's Lamilite Leather boots transferred every bit of moisture away from my feet.

When I finished the hike back out, I took my boots off and my socks were completely dry. I was amazed.

I'm thinking now that I should try that with my Wiggy's Antarctic Jacket just to see what happens.

Maybe I will one day....

Take care,

Mark Hillen

Thank you, Mark, for your letter, it contains two subjects.

Mark forgot to mention the garments were white and cotton.

The white reflets the suns radiant heat waves and the first layer of garments absorbs the moisture coming out of the body. The fabric is cotton so it absorbs the moisture. Now comes the reason they stay cool; the moisture and the cotton fabric are absorbing the heat coming off of the skin surface constantly because the cotton as well as the moisture never stop absorbing since they never reach the temperature of the body. So, they stay cool. In the case of any synthetic such as nylon or polyester they absorb heat until their temperature is equal to the body and then stop absorbing the heat. Further the synthetics never absorb the moisture so one would get clammy.

The people of the Arab world have been dressing this way for several thousand years so we know their method of dressing works.

As for Mark’s experience with the Lamilite insulated boots and Lamilite socks, I am not surprised as I and many, many others have had the same experience.
