If you’re a busy business type strutting from place to place, the C.E.O. Envi is lightweight and ideal for hand-carrying.

If you’re going to be carrying your MacBook Air in a briefcase, messenger bag or travel case, the Envi gives it that little bit more protection.

As well as the outer leather finish, a soft-lined interior hugs the MacBook Air and reduces smudges and fingerprints associated with normal use.

“This sleeve is as amazingly thin as the MacBook Air and the premium black leather is the perfectly stylish companion for your ultra-thin Apple notebook,” said Jose Fuentes, sales executive for Marware.

The C.E.O. Envi is available in black smooth leather with white stitching, for $89.99 (around £46).
