My biggest complaint is the wrap-around hipbelt... if you could offer the option of a beefy fixed lumbar pad with a pass-behind belt that would be great. More load stability.
Funny you mention that. It certainly goes to show how much about packs is personal preference and build, much like boots I guess. One of my favourite features of the packs is the hip belt and suspension. I've never had a pack that carries as well heavy, or 'stays put' on my body under load, like my Evolution does.
It's got to be partially dependent on a person's build and how a guy loads up/adjusts a pack? Some guys love the lumbar pads, others prefer the full wrap... Just interesting to me...
