The Grid-It Wrap for MacBook Air from Cocoon is a minimal case that can organize your smaller gear while protecting your Air. The Neoprene wrap has a back pocket for the MBA. The front has a rigid Grid-It panel with its system of woven, rubberized bands that will hold your power supply, cables, external drive, pens, sunglasses, or other small items you need to carry with you. A Neoprene flap wraps over everything to protect everything inside. The Grid-It Wrap can be used alone, or it could fit inside a bigger bag to protect the MBA from your school books or office gear. There are two sizes: the 11″ Grid-It Wrap and the 13″ Grid-It Wrap, sized for the 11″ MBA and the 13″ MBA, respectively. Both are available in black only and cost $49.99.
