The Osprey Arcane Tote Pack can be your everyday tote for groceries or bringing supplies to the party, and it transforms into a backpack so you can use it as your carry-on for traveling. The zippered top has a unique roll-top closure with an aluminum buckle for extra security. Osprey made it completely out of durable recycled material for sustainable efforts. There's a padded sleeve inside sized for 15-inch laptops.
