Kid Coat with Temperature Gauge

Here's another idea for keeping kids warm as they enjoy the winter weather.  A coat with temperature gauges in them.  The coat would have sensors in key locations to record the temperature of the limbs and torso and then display them on a reading on the chest.  That way a parent could look at the kid and see how they were holding up objectively.  You could also do this for gloves, boots and snow pants.  If you saw a temperature you didn't like you just take them inside.  Or if the kid were complaining too much you could just read their temperature and tell them to suck it up.
