I was looking to eventually get into LARP as of when the situation involving covid-19 dies out and events start again. I saw that certain rules such as global hit points can be altered by what armour you wear. My question is that I was planning on using a foam based material to create my armour, by using certain techniques I can make the foam armour look almost identical to metal plate armour for example. However because foam is much lighter than the material I would be imitating, I would gain an advantage as I would have much more mobility and less strain on my body however with the added global hit points. So, would I be able to make my own armour out of foam and it be allowed in events?
TL;DR: Can I make armour that looks “real” out of foam?
