Best sleeve: Waterfield Designs iPad Smart Case (third- and fourth-generation iPad, $59; iPad mini, $57)
If you prefer the look and feel of a bare iPad, a sleeve is the way to go. Your iPad will be protected when not in use, and easy to remove when you do need it. Waterfield Designs’ iPad Smart Case is a sleek sleeve that securely keeps your iPad in place: The iPad slides in easily, but once it's in there, it won't slip out, even if you turn the sleeve over and bounce it gently up and down. It even leaves room to house a Smart Cover-equipped iPad. The Smart Case's padding won't deflect determined blows, but it will protect against everyday jostling. Plus, the Smart Case has the added bonus of a mesh external pocket that holds a charger, screen-cleaning cloth, or another small accessory.
