These features are a real knock-out: The main compartment has an additional integrated reinforced laptop compartment. It's easy to keep things in order in the front pocket with its organiser compartment. Extension folds provide extra volume, because you'll always need an extra bit of space. Stow away your mobile phone or MP3 player in the secret pocket ready for action. The other features like an integrated bottle compartment on the side as well as loops for charms and keys will also thrill you.
