I have a golite ion and I really like the 3D mesh straps. I think it works so well because straps is breathable. On the other hand all other packs I have seen here are backed by a coated fabric or CCF. That would make the straps non-breathable. I am not sure how much comfort 3D mesh adds in these straps.
Many manufactures save weight by not having mesh backpanel and I havent read any complaints. Why not save some weight by not having 3D mesh in straps?
I am specially interested in hearing from those who have also used packs which dont have 3D mesh eg. GG Murmer, Zpacks. Have you felt any significant discomfort due to lack of 3D mesh?
