I can't give it 5 stars yet because I have not tested its durability, but it seems to be very high quality. This pack is huge, but somehow I have it stuffed to the brim with only 45lbs of weight total with food and no water. This thing looks ridiculously huge and I cant figure out how I filled it up. I've gone through it multiple times trying to reduce load, different packing methods, etc. It remains stuffed to the max no matter what I do. I was very surprised with that. But I suppose the age old rule applies, If you have the space you will fill it, haha. Anyways, It is very comfy to hike in, load doesn't shift, and I don't look like a junk show anymore with gear hanging everywhere on the outside of my pack. I like it!
