Belkin has debuted new Sleeve cases for Apple's MacBook Air to protect the thin notebooks from harm. The company's Slim-Fit Sleeve ($40) is a neoprene cover with no zippers or magnets that cushions the notebook, allowing users to simply slip a MacBook Air into the case and flip the top over to secure it in place. Belkin's Neoprene Sleeves are slated for shipment in March, while all other sleeves are due to ship in May of this year.

Belkin's Leather/Neoprene Sleeve ($50) includes an asymmetrical zipper that offers access to the notebook from the top or side, while the Neoprene Sleeve for MacBook Air ($50) is designed to provide a simple and snug fit. The company's Vertical Sleeve with Strap ($50) offers users the flexibility to carry their MacBook Air on their shoulder or in their arms, eliminating the need to put the sleeve inside another bag.
