I don't often write reviews, but the superb quality of this pack compels me! I couldn't be more happy with this pack. I have had the bag for more than two years. In that time, I have run with loads from 5-25lbs about 3 times every week. I often cram more into the pack than is strictly recommended. Despite the continued abuse, the zipper has never popped. The stitching for the zipper (and everywhere else) is still holding strong. The padding in back and straps is still firm.The only thing that has gone wrong is that the waste-strap buckle failed. Customer service promptly supplied a replacement for free with no questions asked, and, in the meantime, I was able to use one of the tie-down buckles as a replacement, so I was able to continue running.

Customer service promptly supplied a replacement for free with no questions asked, and, in the meantime, I was able to use one of the tie-down buckles as a replacement, so I was able to continue running. That was about a year ago, and the bag is still going strong.The design and manufacture is simple and superb, with each feature showing careful thought. The more you use the bag, the more you realize how much thought went into each little nuance. The zipper pulls are excellent and resilient. The ergonomics of the shoulder straps works very well for me. The mechanism for adjusting the eight of the chest strap works very nicely, but looks like it could be a failure point for the bag -- I have had no problems.One observation about editions: unlike the new version (based on pictures), the version of the pack that I own has two sets of tie-down straps on each side. I often use these to lash a rolled up jacket or shoes to the side of the bag. I don't think I'd be able to do this with the new version, which would be a significant loss of functionality.In any case, this is an excellent bag. If you are a runner or hiker looking for a comfortable, no-fuss pack that can stand up to sustained abuse, do not hesitate.

I love this backpack. It’s incredibly light and looks great. The 4 loops on the outside of the backpack are perfect for small carabiners to hold my climbing shoes, keys, helmet or any other belongings. I wish the top, open piece opened though because it would prefect to cinch down a rope. But I use it for dirty gym clothes after a training session. Something else that would make this pack perfect is deeper side pockets because my 24 hydro flask doesn’t fit. Bladder pouch comes in handy for that reason. High quality from deuter!

This pack is lightweight and very comfortable but has a few downsides:-The front shove pocket is great to have but the way Deuter designed it defeats most of its purpose because it has no stretch to it (items are not secured) and access is quite narrow so even though it's large enough to fit a fleece jacket for instance, it's not possible to insert it.-The top grab handle seems quite flimsy compared to many other bags its size.-The water bottle pockets are quite large thus great if you have a large Nalgene bottle but not snug if you have a smaller one such as a Hydro Flask.
