Good alpinst' backpack - Gregory Alpinisto 50 Pack

I have many Black Diamond climbing equipment - harness, quick draws, carabiners, tape and slings, treking poles, crampons, but no backpack ever. I was attracted by Alpinisto's color, very special green and bright in mountain. But other than color, it is very good pack for alpine climbing, comfort and durable, tecthincal and well designed. I believe that it is the best alpine pack in the market as now.
