How do they work? The higher the number the better? How do you determine how warm the insulation is going to be? Any help would be much appreciated!

There's a clo chart somewhere but i never found it very useful because it's an oversimplification. For example, wool sweater is on the list, but not all wool sweaters are the same. Some are loosely woven, some are thicker...obviously some will be warmer than others.
Instead study heat transfer coefficients (How quickly heat passes through a material) there's equations you can put into a spreadsheet to tell you all kinds of things ... how thick you should make a down quilt to stay warm at 20° with a 15 mph wind for instance. Granted, you might need to do some research to understand the varibles in the equations, but you don't need a degree. (I don't have one at any rate)
