honestly, the designs are flawed at best. the problem with taking the top off the helmet is that it makes the helmet useless. let us remember why we wear helmets- to protect our brains from damage sustained from enemy fire, shrapnel from explosions, and yes, even the sun. and the cloak? seriously, why wear a cloak? will the poor little spartan catch a sniffle if he doesn't stay warm? the effect is interesting, reminding me somewhat of a futuristic japanime show. but in terms of feasibility and fieldability- well, to say that a redesign is necessary is an understatement. no vote.
