There is much more in this book than just "thickness equals warmth". The info on vapor barriers, moisture condensation in fabrics, body heat reflection, and heat loss through breathing are all excellent. Much of this information is not widely available, and in fact is considered "wrong" by a large group of outdoor "experts". Buy the book, try the recommendations, and become one of the few true cold weather experts yourself.

This book is easy to read, and it's easy to apply the basic secrets for staying warm. After 34 years of chilly Canadian winters, I've FINALLY found a way to have warm fingers and toes all the time.

This is an OK book, but not worth buying. The book is too repetitive, and could be shortened to a few pages. The basic idea of the book is: warmth = thickness. Most insulation insulates because of the dead air space it traps (not because of what the insulation is made of), so the idea of staying warm is to just have enough dead air space. So, the "Secret of Warmth" is to just use something to make dead air space and seal it up good so the wind won't blow in and the air won't leak out. And don't get it wet. There, you've read the book.

The book provides very good advice on several ways to create insulation when none exists, as well as giving expert guidence on the make-up and effectiveness of different fabrics and materials as insulators.

For as inexpensive as the reference is, I say its a good buy.
