Designers Holger Gräf and Daniel Lantz have earned a reputation for their Old World-New World ways — i.e., applying classic touches to work that meets a modern traveler’s needs. For example, take their GRÄF & LANTZ MACBOOK CASE: Made from felted Merino wool and fashioned for the MacBook Pro and MacBook Air, it’s a smart example of the elegance of opposites — the most advanced technology protected by a textile that is said to be the oldest in the world. The company imports it fabric from Gräf’s native Germany, a country with a rich felt-making tradition, and crafts it into beautifully minimalist cases defined by simple lines, unorthodox textures and Gräf and Lantz’s signature exposed stitching. A leather flap, which folds and snaps to hold the laptop snugly inside, creates a happy marriage of form and function. In charcoal, cobalt blue, green, red and chocolate.
