Yea, at first glance they seem like that at most they'd just move up and down but in some scenes you can clearly see that they move back and forth too. This begs the question of what to make it out of and how to attach it to the armor although I'm thinking that I can make it out of whatever I choose to make the rest of the armor out of and just attach it so that it can move around fairly freely. On the other hand I might make it out of something flexible and attach it loosely too, what do you all think?
