The thought that always occurs to me when I'm exercising—besides "why am I exercising?"—is, "I wish I had more oxygen right now." The Oxyfit backpack gives me up to 50% more oxygen.


Here's how it works. The tube, which goes in front of your face like you were Neil Patrick Harris answering phones for a Haiti telethon, pipes oxygen from the backpack directly to your breathing space. With this, you'll raise the normal 20% oxygen level of Earth's atmosphere that you get to a more Olympic-level 30%. Is this $2681 backpack worth it to help you exercise longer by giving you more oxygen? That depends on how fat you are. [Japan Trend Shop via Oh Gizmo via Fashionably Geek]
