Query: Quality bag

This bag is well constructed and durable. The only thing that could be better was the attach points for the shoulder sling, but I have it stuffed full; beyond the point of zipping it up or even using the handles and the shoulder strap is working fine. If it breaks, the quality of the bag is such that I would take it in and have it repaired and upgraded.**Update**Bag has held up great after months of use. The zipper has proven to be a novelty; even with a few tools you have to force the mouth closed, hold it and it takes two hands to run the zipper (3 hands total). I tried it once (for a few minuets) and gave up. As an open bag it has worked very well for me.
