that could be true but(i'm not trying to be a jerk) on what i read up on is it's acessed via wrist gauntlet but this is why they need their helmets.... the need to breathe dont they, well without their mask they could only survive a week on earth at best because they need their methane rich envoirment to breathe, thats why they usaully hunt in jungles (with the exeption of city hunter) near the equator, becaus it has that eviorment, and so they strain there lungs alot less, also a pred would die if sent to a planet its lungs could not take meaning they would have to keep their mask on at all times. It's not trival, they need it to breathe on certain planets, otherwise they would not take it off on earth, notice when in low oxygen eviorments they always keep their masks on, which is supposedly so they dont sufficate, it could be used to cloak but as bloo said earlier, why the hell would you be wearing armor that couldn't cloak without a helmet, it wouldn't be so... i dont know cool as it would be the why the fucking hell can't it cloak, their supposed to be excellent with tech and highly intelligent beings(still dont know why they haven't used water-proffing) otherwise they would only be super-humanly strong and durible and then they could not travel to other worlds, as deathdrop said, if you can fit a thermo-nuclear bomb inside a wrist piece you sure as hell can fit in cloaking without a helmet, and besides this site even has the cloaking seprate from the mask. So who knows what the awnser is, it's one of those mysterys that will never be solved unless you talk to the people predators.
