Acme Made's Skinny Sleeve MBA is one of the more attractive and well-designed Air sleeves we've come across. It's made out of StretchShell neoprene and is both water- and stain-resistant and doesn't have any zippers, so you don't have to worry about scratching your Air. An elastic band keeps your laptop securely in the sleeve. It's available in matte black or purple.
Ever since Steve Jobs unveiled the first MacBook Air and showed it sliding it out from a manila envelope, several companies have offered up leather manila envelope sleeves. In terms of cost,
BoxWave's Manila Envelope is about at the middle of the pack, with some companies selling more affordable models and some more expensive.
CaseCrown is known for its value cases for a variety of mobile products and its faux-leather Book Cover Clip On case is no exception. It's available on Amazon for around $20 and is clearly one of the better deals in this roundup. CaseCrown also makes a simple Clip On Clear case that sells for about $22.
If you're looking for some serious protection for your MacBook Air, you can't get much more serious than the G-Form Extreme Sleeve for Laptops, which is made out of material called Poron XRD that's lightweight yet is able to absorb a lot of impact.
Price: G-Form makes two models: the one that fits that 11-inch Air is $69.99, and the one that fits the 13-incher is $79.99.
Moshi's iGlaze clip-on cover is similar to the Speck's SeeThru Satin covers. Pictured here is the translucent model; it also comes in "stealth" black and "pearl" white. Nice cover, but it should cost less than $50.
Pad & Quill brings its book-bound style cases to the MacBook Air with the Cartella, which features a form-fitting wooden tray. We like the iPad version of this one, and the Air version makes for an interesting case option. These cases are all handmade in Minnesota.
We wanted to throw some lower-cost sleeves into the mix, and this one from RooCase, called the RooCase Super Bubble Neoprene Sleeve, fits the bill. It gets its name from having bubble-shaped neoprene cushioning on the inside.
Sena's Zipbook is a clamshell-style zip enclosure case for the 13-inch Air that's made of soft leather and nicely padded on the inside. It's definitely got a swanky design and is a great case if you can afford it.
Speck's SeeThru covers are lightweight and made of translucent hard plastic. The standard model has a smooth finish which while the Satin model has a soft-to-the touch "satin" finish. They clip on to the top and bottom of your Air and are available in several different colors.
Timbuk2 makes some interesting laptop and tablet cases, and I thought it was worth highlighting the Crater, which is available in three color schemes.
It has a rubbery, meshlike feel to it, and it's very lightweight. The key feature is that if you hold it up to the light--or just look at it--you'll notice that it has lots of little perforations or "craters" in it, and light passes through it.
San Francisco-based WaterField Design makes really nice cases for a variety of products. This Air Travel Express is designed to fit small laptops like the Air and offers power-cord storage as well. It's available with different trim colors.
This WaterField Suede Jacket Sleeve is superthin -- it literally feels like a piece of cloth, but it's suede. It's not going to offer much protection, but it does cover your MacBook Air and prevent it from getting scratched up. It comes in vertical and horizontal versions.
Price: $25-$29 (13-inch versions are more expensive)
