WaterField Designs' $79 Smart Case doesn't grab the eye the way some of the MacBook Air's flashier sleeves and cases do, but despite this, it may be my favorite yet.
Rickshaw's Zero Messenger is comfortable and fashionable, and it keeps your laptop secure inside. As a bonus, it's made locally from quality, eco-friendly materials.
Kempton and Darrow's Rough Night Deceiver is pricey, and by taking the place of a large purse and a laptop bag, it can be bulky. But if you're a laptop-toting fashionista with some cash to spare, it will protect your laptop while holding more stuff than you know what to do with.
Overland Equipment's Cambridge is a great option for people who need to carry more than just their laptop.
If you're looking for a streamlined, quality MacBook Air case, you can’t go wrong with either Waterfield's Wallet or Travel Express.
Knomo's 11" Leather Envelope for MacBook Air is sturdy, cushioned, and attractive, if a bit heavy relative to the MacBook Air itself.
For a stylish, efficient messenger bag to cart around urban areas, Brooklyn Industry's City Bag Medium gives quite the bang for your buck.
SGP’s first foray into sleeves for Apple’s smallest laptop, the Gariz Modern Series Genuine Leather Case, is attractive and well-made, but pricey and a bit too snug.
For storing your MacBook inside another bag or suitcase, or for some extra protection while carrying your laptop by itself, Thule's cargo-carrier-inspired 13" Protection Sleeve is a solid option.
The 70s Girls Laptop Case won't let you bring a lot of items along for a day, but it's great for running out for a quick meeting or to do some work at the coffee shop. You'll want to check out the adventurous prints before buying, but the $68 price tag is a bargain for a bold, comfortable tote that keeps your laptop snugly in place.
