Shields are for defense, and if you've ever been in a high school hallway during class change, you know that a good defense is just what you need. If you want to get somewhere quickly, despite swimming upstream like a salmon, you'd best have something to protect your stuff, like this Warcraft Alliance Shield Backpack.
When you sling this Stormwind Shield across your back, you'll feel confident that your stuff is protected by the Alliance. The sturdy lion design on the outside shields the contents from normal buffeting, but we wouldn't put it up against a sword. (Hopefully you don't meet those too often.) And there's a padded iPad/tablet sleeve inside the main compartment that'll keep your device safe, sound, and still ready to draw at a moment's notice.
100% polyester (presumably minus all the plastic bits on the outside)
