An American company called Play has started selling underwear with a built in pocket for an iPod.

Play offers a variety of men's boxer briefs with the media player holder, retailing for $22 a pair. A line for women will be available shortly.

"The iBoxer is the world's first and only boxer specifically designed with a pocket engineered to hold an MP3 player or cellphone," said the company in a statement.

"As part of the launch of the iBoxer, Play is offering three free downloads from iTunes with every purchase of two Play items.

"It is sure to be a hit among high school and college students who like to hang around the house or in their dorms in their underwear listening to their iPods or carrying their cellphones around."
