It seems to be exactly what it looks like.Sorry, is that literally just a battery in the trousers? Ergo, you have to charge the trousers? I assumed it was something like a kinetic energy recovery system using a bleeding-edge fabric, generating an electrical charge from ordinary movement. If it's just a battery in the trousers, WTF's the point? Buy a separate portable phone charger and use it with any trouser you own. Or no trousers at all. Bet they cost a stupid amount of money too.
"It will house parts from the Nokia DC-50, a portable wireless charging device with built-in battery, in one of the front pockets of the pants."
"The price point has yet to be set, but Mr Sauvage predicts that the trousers will cost, “over $340”."
"Mr Sauvage failed to make the trousers machine washable."
They could glue the DC-50 to a Pocket Protector instead, so you wouldn't need 5 pairs of $340 pants between the week-end dry cleanings.
