20% project

My twenty percent project is to create football gear (mainly shoulder pads and helmets) that are good at keeping players cool. In the month of September I researched whether it would be better to try and make shoulder pads and helmets lighter which would make less work for the player wearing them, or I would try to put some sort of cooling system in the pads. After my research I discovered that it would probably be better to try and put a cooling system in the pads because making them lighter won't necesarilly make you a lot cooler. By the end of October I want to know or at least have a good idea on how the cooling system will work and how I will get them to fit in the pads.
