XtremeMac introduces three iPhone cases for different needs.

The Onyx iPhone case is made of smooth, black leather with contrasting stitching and an integrated belt clip. XtremeMac says the Onyx is fit for the boardroom. I say belt clips are just not cool.

The XtremeMac SportWrap (photo) for iPhone offers complete protection in a sleek, neoprene armband that’s perfect for protecting iPhone while working out. The arm where you have your iPhone strapped too sure will develop more muscle. Maybe you should get two iPhones. Finally, the TuffWrap for iPhone is a two-tone case made of durable silicone that provides sporty protection for people on the go.

Onyx will be available for a suggested retail price of $29.95. SportWrap for iPhone will be available for a suggested retail price of $29.95. And TuffWrap for iPhone will be available for a suggested retail price of $19.95. Each case is backed by XtremeMac’s Limited Lifetime Warranty and will be in select retail outlets in August. They may also be preordered via the XtremeMac website at site. See also the recently announced Belkin iPhone accessories.
