Electronic Devices with Fabric Bands

A head-mounted device may include a main housing portion and a fabric head band for supporting the head-mounted device on a user's head. The fabric head band may include first and second flat knit end portions without ribs and a ribbed fabric extending between the first and second flat knit end portions. The ribbed fabric portion may include a stretchable inner fabric layer formed from mesh fabric. A first set of ribs may be formed on a first side of the inner fabric layer and a second set of ribs may be formed on a second opposing side of the inner fabric layer. The head band may include one or more pockets. A pocket along the border of the head band may receive a cord. A pocket at one of the end portions may receive a user input device or other electronic component.
