Let's get a rather important fact out of the way first: it's just a concept. Little boys reading this should cross it off their list to Father Christmas now, before their hopes rise even higher.
The Sidewinder, designed by Jordan Swartzentruber, is a Self Contained Breathing Apparatus, created in that magical, faraway Concept Land where firefighters use the mask to aid breathing when in thick smoke. It also features a voice amplifier - for yelling at cats to get out of trees - plus GPS, a torch and a small outer display for reading information on each particular situation. It probably auto-tweets to Twitter too - most things seem to these days. [Tuvie via GearFuse]
