The North Face Crestone 60 Backpack
Hopefully I can save you some money. I first purchased the North Face Overhaul 40 Travel Pack, great pack, only issue is that it was too small for my situation. I needed to be able to carry a full set of work cloths (shirt, t-shirt, pants, socks, and shoes) and any additional work stuff (laptop, papers....). The North Face Overhaul 40 Travel Pack just didn't cut it. I could fit all in but if was smashed in there. I workout before work so that is why the cloths are needed.
The North Face Crestone 60 Backpack is working out great. The OptiFit System does make the pack fit perfectly to your back. The layout of this pack distributes the weight evenly. Only complaint is the sleeping bag pocket zipper. The zipper is a half shaped moon and it is difficult to easily open and close the zipper. Know how most zippers are in a straight line? There is a reason. All in all a great pack, looks good, I have the Black/Charcoal color and looks like I should be out day packing but I just use it to and from train, work and home.
