Its great that they are doing research to try and make those costumes lighter and cooler, however many of the lighter cutting edge materials are terribly expensive. Hopefully in the next couple years they will be able to make those costumes out of a spaceage polymer that is light and breathable.
Before ever reading this article I already knew how hot and uncomfortable those character suits were, and I always used to comment to my wife how shocked I was that more people don't pass out in them during the hot summer months.
To those of you here who do the character thing, THANK YOU!! I just want to thank you for putting yourself thru hell (or what may feel like hell heat wise) to bring joy to a child and make a fond memory that will last a life time. :sohappy:
