I have had my Asymetrix 20 backpack for almost two and a half years now, not a single thing on this amazing backpack has ripped, broken, or gotten jammed. I have stuffed this thing full of stuff and the zippers hold.

I think the biggest test of this backpack's strength came when I was carrying about 100 pounds worth of extra weight and the backpack supported most of it. I walked almost half a mile with this extra weight and could barely tell by the end.
