Remember the Grid-It organizer I wrote about a while back? Well as it turns out, the guys at Cocoon have made a backpack – the Cocoon SLIM ($80) – that actually incorporates a large Grid-It organizer into one of its two main pockets. The other main pocket can hold a 15" MacBook Pro, and there's even a separate iPad compartment.

This backpack is a great choice for keeping your stuff safe and dry, with its water-resistant ballistic nylon exterior and waterproof zippers. The SLIM earns its name by only being 3.5" thick even when fully stocked with your gadgets and other gear.
