The new Race Case makes gliding through the airporace casert a breeze. Created by Suitsupply, an Amsterdam-based men’s fashion retailer, the innovative device is a luxurious suitcase mounted on a Razor scooter. The lightweight frame easily folds up for storage. The carry-on, which has room for a 15-inch laptop and other gear, is made of Italian calf leather and features an extendable leather-grip handle. It retails for $599.
