This has been my favorite backpack ever. It has a couple excellent Features that I loved especially for cycling or being in the city:
- reflective stripe
- easy opening / closing
- extra compartment for laptop
- extra compartment for wallet or pens
- waterproof
I have used it for a long time but I just got another one as a present so I am letting this one go. It has marks of use, please see pics. But zippers work perfectly and i never had issues with it.
