XtremeMac today unveiled its new TuffWrap silicone case designed for Apple's second-generation iPod nano. TuffWrap is a rugged silicone case designed to protect the iPod nano from scratches and dings while offering complete access to the player's functionality. The case features ridged sides for a sturdy grip, as well as removable clickwheel and screen protectors. Sculpted from thin, soft silicone, the clickwheel protector is a form-fitting insert that offers tactile identification of the clickwheel and center button. The screen protector is a hard plastic insert edged with soft rubber to prevent direct contact or scratching of the screen, and the TuffWrap case includes a detachable belt clip that rotates as well as locks in a variety of positions, securing excess earbud cord length. Each TuffWrap comes with a special universal dock insert, allowing the Nano to dock without removing the case. TuffWrap cases are offered in several translucent as well as opaque colors, and are available for pre-order for $30 via the XtremeMac website.
