Dunno what the designer of those were smoking when they thought Klingons would wear that. Don't get me wrong its very well made but that is something for a fantasy game like for Thor or skyrim or somit. Not exactly the Klingon motto. Light armour so they can move quickly and freely and not hide behind armour as its not the Klingon way also how on earth will their big foreheads get under them tiny helmets because the look of the helmets are smooth and would fit a human no prob but a klingons forehead i don't think it would. Would you?
I am constantly disappointed that nobody imagines a technologically advanced Klingon. It's always something that looks like it came from a medieval era, and while there is canon to support some of that. It requires me to suspend disbelief too much to imagine an advanced race having their best armor only suited for a jousting match.
