It’s surprisingly spacious for how small the bag is, which makes it portable/practical and comfortable while having it on.
Promising review: 'I cannot say enough amazing things about this backpack. It's also made of nylon, so it's waterproof and has a strap to change it into a shoulder bag. Not only does the backpack open from the inside, but it also has a phone pocket, document pocket, front zippered pocket, and an exterior side pocket.
