| During the winter, the temperature outside varies a lot throughout the day. It may be 20 degrees in the morning, but by moon it will be in the 50s/60s. This makes choosing a jacket of appropriate thickness very hard. Choose a thinner jacket, you will be fine during the day but feel cold in the morning and at night. Choose a thicker jacket and you might start to sweat during the day, but you can't just take off the jacket because then you will feel cold. The solution to this problem is to make a jacket that can sense the temperature outside and adjust the "thickness" of itself. To adjust its thickness, we will use the insulating property of air. As opposed to a normal jacket, this jacket will have pockets of air inside (think bubble wraps except the cells are all interconnected to each other through bridges). This is then connected to a valve and a air pump which can pump air in/let air out. When the outside temperature is cold, the pump will activate to fill the bubbles with more air to increase insulation, When the outside temperature gets warmer, a hole/fan will be used to let out air, thus making the jacket not as warm. There will also be a sensor that determines how "thick" the jacket is currently. In the case that the air pockets are not entirely air tight, and that the jacket becomes too "thin", the sensor can sense this and tell the pump to pump more air.
