I haven't had this pack long but I have done quite a few miles with it and, so far, I'm not terribly impressed but I will admit that it is a good pack. The one thing that really bummed me out was when I got the top caught on a little thorn and it ripped. I'm sure it has to do with the material being so lightweight but I didn't expect a little thorn to actually penetrate the fabric. I haven't had the hip belt custom molded yet and I don't know if I will, as it seems to be adjusting on it's own. However, I have gotten blisters on my pelvis but I'm going to thank my bony hips for that. I'm hoping this will subside the more I wear the pack. But overall a great pack that can carry some serious weight and not feel too bulky.
