I'm used to the mesh panel from my old Arcteryx pack so it is all right with me. I think it really adds to air ciculation. Waist belt is ok with right load distribution. When pack is full it seems to work best. When pack is half empty load shift very easily since the belt is anchored from the center and doesn't "hug" the entire bottom of the pack. Belt itself is very well padded and comfortable. I solved my shifting problem by placing heavier load on the bottom. It is a great pack for the money. I'm trying to justify Kifaru marauder with side pockets and I just can't find anything really wrong with my MAP.
