For spring 2015 Nike released their latest iteration of the popular Tech Pack collection. Their latest form, Nike Tech Aeroshield provides a featherweight barrier between athletes and their temperate surroundings. Where many other jackets cling to the wearer when worn in balmy climates, the Aeroshield technology features internal flocking nodes that work mechanically to maximise space between the garment's outer shell and the wearer's skin. Combined with the laser-perforated ventilation, the flocking allows air to circulate more freely to help keep the wearer cool and comfortable. The Aeroshield technology is also incorporated in the Nike Tech Windrunner to add a water resistant yet breathable layer to the jacket.
