they do work amazingly well though

It's incredible how much warmer you are on a bike when you put on a decent gilet - even though they feel completely insubstantial, like there's nothing at all to them.

Guess just goes to show how much your core temperature matters - and something to do with how heat escapes or can be kept in by a thin layer of material. Or something.

They make a huge difference, anyway.
