Marware has introduced its new Sportsuit Convertible cases for the fourth-generation iPod nano and second-generation iPod touch, along with another Sport Grip case for the nano 4G. Made from Lycra and Orka-skin material, the new Sportsuit Convertible 3-in-1 case leverages Marware’s Multidapt system to function as an armband, belt clip case, or low profile sleeve. It features a clear vinyl protector for the iPod nano’s Click Wheel and screen or the iPod touch’s screen, comes with a Multidapt base, armband, belt clip, and key pocket, and is available for pre-order for the iPod nano 4G ($30) and iPod touch 2G ($35). Also new is the company’s Sport Grip for iPod nano 4G. This form-fitting silicone case features open access to the screen, Click Wheel, headphone jack, and hold switch, a built-in protective dock connector flap, and textured sides for added grip. It includes a clear film protector and cleaning cloth, and is available now for $15. Finally, Marware announced that it is now shipping its Glide case for the iPod touch 2G. The pocket-style leather case features a microfiber interior, a dual-purpose strap for easy removal of the touch, a Velcro closure for a more secure fit, and an included screen protector and cleaning cloth. It sells for $25.
