I have a black A-III that was given to me prior to deployment to the desert in 2001. This pack is really stout! I carried it with me every day and basically lived out of it for six months. I put a three liter CamelBak bladder in the hydration pocket and when I returned I bought two accessory pouches that mount on the side for more space. I use it during my weekend outings and have plenty of room for my two/three days worth of food/gear. The heavy duty zipper are awesome! I don't see how they can break. As with any piece of gear It depends on what you intend it to be used for. It's a medium size pack that has a lot of room. If you want it for an everyday pack to carry a few items then it may be too big for you. If you want a pack that is sturdy and will hold a water bladder and a lot of gear, then I highly recommend it. Once I wear my A-III out, I will purchase another in a heartbeat!.
