I think from the heli pro down the dekine series is the bomb. You get a well balanced pack that stays so close to your body you hardly know its there. This is my day pack or inbounds OB pack. In Japan there are alot of OB areas inside the resort that require gear. The wife uses the heli and its prefect again for what it is.
Anything larger and I find that there are better packs out there.
Ive broken a buckle and a zipper on mine but when you fly though the trees and snag something its gonna happen to any pack.
80 bucks is a bit much if your not gonna use the pack for what it is.
P.S. JAPAN HAS SICK POWDER
