Outdoor Gear and Thermodynamics: How to Layer for Optimal Comfort-Steve Greapel

Rating: ****

This extremely informative article on the basics of how our skin works and how to layer, will definitely help and beginner grasp these concepts with ease.

The article provides an educational approach towards layering and why it is important. It starts off by explaining how heat is conducted through its various means (Conduction, Convection, and Radiation). The author then goes on to explain how our skin works with different materials and how it exchanges heat with its surrounding. Next, he uses examples to support his facts, for example, how rapidly cooling yourself off will end with hypothermia. Finally, he gives tips to use while packing your gear, some examples of what you should wear in certain situations. All of this is supported by images to further explain concepts.

After reading this article, there is a lot I can take from it. First of all, I now know the basic functions of our skin and exactly how it helps regulate our temperature, which make me consider different materials for different situations. I know that it is essential to wear a “Second Skin” while in winter/cool climates. A very handy feature on most jackets or pants is a vent, which allows the body to cool without putting it in shock. Since I’ve read this article, I will now be more careful when choosing clothes for physical activities, and I would definitely recommend this to anyone.
