Sometimes, you just need a breath of fresh air. You'll always have one with you if you're wearing the O2 bag. It's essentially a backpack containing a battery-powered oxygen generator, making sure you've always got fresh oxygen in tow.

It's a great little contraption, equally suited for trendy folks looking for a portable oxygen bar, mountain climbers, and people suffering from emphysema. But really, it'd probably be best suited for people in high elevations where the air is thinner. It'll give you the precious oxygen that your body needs to survive, keeping you from getting out of breath. Of course, it's not cheap, with the prices ranging from $880 to $1,150. But hey, you'll be happy to have it when you really need it.
