You have your iPad Pro, iPad Air or iPad mini — and you certainly want to carry it with you wherever you go. In which case you should check out the $59 iPad SleeveCase from WaterField, which offers great on-the-go protection.
The messenger style bag is cushioned with neoprene and wrapped in tough ballistic nylon shell with a "screen cleaning" Ultrasuede lining. It also sports an impact-resistant, screen protecting insert. The iPad SleeveCase functions as a stylish stand-alone case or can be inserted into another bag. With it you don't have to take your iPad out of its compartment when going through airport security, as the SleeveCase is TSA Checkpoint Friendly.
The Ultimate SleeveCase for iPad also has a convenient side pocket where you can stash earbuds, a cleaning cloth, etc. It's available in a choice of grey Indium or brown, naturally-tanned, leather trim. All this combines for a professional, elegant look. Waterfield also offers a removable shoulder strap and piggyback accessories as options that attach to the case's two metal rings on each side of a Velcro-secured strap.
Note that with the Ultimate SleeveCase you can't use the iPad when it's inserted. Of course, it's not meant to let you do so. It's designed for stylish protection while you're out and about.
