I love this bag. I use every absolutely everyday, rain or shine. Its big enough to carry pretty much anything I need yet not big and bulky. I will never use another manufacturers bags after using this for six months now with little to no signs of wear. It stands up to anything I throw at it and holds a ton.
The only thing I would have loved to see in a built in laptop sleeve. I understand a daily commuter may not be its primary function but it would have made this bag that touch better.
Overall this bag is worth every penny, when you buy this bag your are paying for versatility and the highest quality. This may be the last backpack you ever buy.
