I've been buying this backpack for a few years now. I think this is my third one. For the money you can't go wrong. I especially like how light it is. This really makes a difference to me. My Wenger backpack is larger, but even empty it's quite heavy and I only use it if I really need more space. If you commute by bike or on foot this Lenovo backpack should be a good choice. When I spend the extra money for an ultralight laptop, I don't like to then carry it around in a heavy backpack.After heavy use and bike commuting one year I did manage to rip some seams on the secondary compartment. Convenient port cut-outs line the edges of the case.Made from polyester material for a strong and durable design.Made from polyester material for a strong and durable design.
