If you are a serious geek that likes to show off your geekiness there are all manner of shirts and other clothing items that will do the deed. None of them will mark you as geek as much as the Syte shirt. This black t-shirt has a pocket in the front that you can cram your iPhone or iPod touch into.
The shirt will hold the device in either portrait or landscape modes. The clear pocket will allow you to show the people around you what you are watching, even if you can't see it yourself. I guess this shirt is sort of like the people that spend money to put screens in the headrests of two seat cars just so the people behind them can see what they are watching.
The shirt is unisex and comes in S-XXL sizes. The small through XL versions are $39.95 each and the XXL size is $44.95. The clear window is dust and water-resistant and you can control the iPhone touchscreen through the clear protector. It appears that the pocket zips shut at the top so you can do cartwheels without worrying the iPhone or iPod will fall out.
