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.

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.
