Once again then - what is layering?

We wonder wheather layering is the answer - then we say wearing anything is layering. This is pretty much a load of BS folks, trying to avoid the question.

The question is "should you carry a lot of (thinner) layers to put on and take off as the weather changes?" The operative part is "a lot of thin layers". The idea being that many thin layers are more adjustable.

Frankly back to the OP I think the answer to your sacred cow challenge is "NO, the layering concept was somehow one of those "good ideas" that should die and go away. It has no value because it doesn't mean anything. Its like the idea that you will stay found if you own a compass. A myth or a non-statement - sort of like political fact...
