Training can sometimes be a lonely & gruelling experience so why not monitor your progress or have some entertainment along the way. Made from 65% nylon, 15% elastane & 10% polyester, this Nike+ Forearm iPod Touch/iPhone Carrier Sleeve has been designed for easy access & interaction during any activity. Featuring Nike's Dri-FIT fabric, this pulls sweat away from your skin & help you feel cooler, drier & more focused on performance. This sleeve has also been constructed to be water-resistant meaning that it truly stands up to the elements when you take your training outdoors. A practical & plain black design easily houses your iPod Touch or iPhone, with clear visibility of the screen on your arm & the inclusion of a hole to feed your headphones through.
