ThinkGeek has created an awesome officially licensed backpack modeled after the in-game Traveler’s Shield from The Legend of Zelda: Breath of the Wild. It is available to purchase from their website.
Cram all your books into this backpack modeled after the Traveler’s Shield from The Legend of Zelda: Breath of the Wild to protect them. It has a padded back and straps (to protect you), and a double zippered closure so you can get to your stuff quick. Because we’ve heard it’s dangerous to go alone.
A sturdy shield loved by many an adventurer, this Breath of the Wild Shield Backpack will shield your important stuff from the real world. As an added bonus you can’t get in game, its bright blue features a print of the Sheikah’s Eye Symbol and a padded laptop/tablet sleeve. It’s best suited to helping you carry stuff, not so much defending against weak monsters or animals. Oh, and don’t actually use it for shield surfing.
