There are plethora of sportswear and hoodies currently on the market with integrated music controls. Zip, a project developed by Jennifer Darmour (ElectricFoxy), aims to push the concept one step forward by forgoing the push buttons and using the garment's zipper instead for volume control. Using a resistive zipper, the volume increases as you zip up the garment. 

The garment is designed to be easily manufactured so I must admit that I'm sensing a trend here for 2011. Will we see more RTW wearable tech hitting the market?
