dont know them cant talk good or bad about them there are a lot of great packs out there best i can tell you is find what fits you best and can handle your demands for me that is the outdoorsman opticshunter
I have not used the packframe, but have two of their smaller packs and a tent. They are well built, comfortable, and are holding up very well. If it fits you well, I would not hesitate to buy Alps gear. They produce good quality backpacking gear, so they are not strangers to outdoor equipment.
