I bought this pack 1.5 years ago for my work bag. I attached a molle pouch on the front pocket of the bag and a molle water bottle holder on the side (for my second water bottle). I used it about 5 days per week and opened/closed it multiple times per day. It holds about 20-25 pounds of gear. I was so impressed with it's durability that I bought a second for non-work use and two for gifts.

The problem occurred yesterday when the outer front pocket (the larger outer pocket) zipper gave out. This is clearly the only noticable design flaw of this pack. The main pocket has a heavy duty zipper on it that would never give out. This pocket has a cheap standard zipper and tight edge corners. Since it zips all the way around the pocket and is vertical, that zipper takes on whatever weight is in the pocket on the outside compartments and whatever molle attachment I have on the pocket. My attachment weighs like 5-7 pound and probably wore down the zipper strength over time. I think that opening and closing the pocket multiple times per day did the most wear. I noticed that it always got held up at those tight corners when trying to close it with one hand and the corner is where it gave out. I feel like the manufacturer did not account for someone actually using the molle webbing on the bag and they should have made this one outer zipper heavy-duty as well.

I am debating buying another or switching brands. It seems like other packs have the same flimsy outer zippers problem or are much more expensive. This bag used to cost just over 20 dollars but, even now, it seems to be a decent deal considering how it lasted 1.5 years under heavy use conditions. Perhaps it will last longer a second time around if I am gentle and use two hands with this pocket (now that I know it is weak).

The two pictures are of the broken outer pocket zipper and the heavy-duty main pocket zipper (for comparison).
