MacBooks may be great laptops but they are not designed to be abused. It is easy to break these tiny laptops. That’s why you want to invest in a decent case or jacket to keep your laptop safe. The Booq Viper MacBook Air Sleeve comes in two sizes for 11 and 13 inch MacBook Air machines. It has a semi-rigid design and a magnetic clasp. The exterior is 100% natural jute. This won’t add a whole lot of bulk either. These will cost you at least $39.95.
