Last week it was Motorola and Burton, this week its Motorola and Oakley as the telecommunications company slowly but surely makes ties with more clothing companies.

Motorola has announced it will work with sunglass maker Oakley on technology to make wearable communications devices.

The companies expect to have details on their advances and preliminary designs ready to be unveiled by mid-year, with the goal being "evolutionary and innovative products for consumers who want hands-free, untethered operation of their electronic devices," according to a jointly issued statement.

The venture echoes an earlier agreement between Motorola and snowboard and accessory maker Burton, unveiled recently at the Consumer Electronics Show, to build jackets and headgear that use Bluetooth to enable a skier to listen to music or make phone calls without using their hands.
