From class to practice to study sessions with friends, the Tardy Slip Backpack 25L has just what you need to keep going all day and beyond. Part of their Educated Series of compatible backpacks, and accessories, this 25-liter pack features a roomy main compartment with a padded laptop sleeve that fits most 15-inch computers, along with an exterior zippered pocket (perfect for stashing the compatible Hall Pass Wallet) that also contains a key clip. A stretch mesh water bottle pocket keeps your favorite beverage close at hand, while external bungee storage allows you to stash a hoodie or windbreaker for when the temperature drops.
