I purchased the Ibex 17" pack about a year ago for use with my work laptop and assorted gear I had to carry. I had not used the pack more than two months when the mesh facing on the left shoulder strap separated at the seam and started to unravel. It was clear this had happened because of the load on the strap, which was only a laptop, power brick, and a few DVDs and a lock. Not more than 20 pounds, total. For this to happen on a laptop bag designed to carry a 17" laptop and room for several books, water bottles and other gear was unacceptably poor quality in manufacturing. The Ibex is a great bag otherwise, and by the other reviews I think mine may be an exception, but it should not have come apart in any event.
