Nike ACG Communications speak easy Jacket, used conditions from 2004 This is a limited edition jacket in full Gore-tex XCR. Still waterproof now as it was 15 years ago. Pretty revolutionary technology for its time, the jacket is able to be connected to certain radios and be used for hands free communications, using the PTT button on the front of the jacket and the built in microphone. The components for the radio set up are all unopened in the box. A radio would be needed to be be functional, and also some phones work with the device too. (may need an adapter for modern phones to work) Crazy rare jacket from the all conditions gear range, featuring underarm zips for breathability, waterproof sealed zips, and an adjustable ski skirt inner. Size Medium but also fits a large.
