Nudown is out with an interesting line of outerwear. Calling it “Nutech Technology”, each jacket or vest (only comes in two designs) comes with a built in pump. The pump allows the wearer to manually force air into air pockets found on the outer linings of the clothing; creating a layer of air between the fabric and the outside temperature. The air then traps your body heat creating further insulation from the winter chill. If you start feeling hot, just release some of that air to cool yourself down. Coming in at $350 for the jacket and $250 for the vest, this is another example of how fashion designers are trying to merge tech and style.
