That is likely a contributing factor, I use the hell out of my backpacks... carry daily, they go camping with me, go on travel trips, I often have them heavily loaded, they get lots of use and wear and tear. The most common failures I had were straps coming off or holes wearing in the bag.

Now I have a Hazard4 bag that I've been carrying for like 8 years and, other than being a little dirty, it still looks brand new.
