Ha you are very correct. More words needed here.
It is black VX21 from dimension polyant. I used that for the back, the top of the shoulder straps, top of hipbelt, as well as the bottom and bottom of the front. I raised the mesh off of the ground by extending the vx21 2" onto the front of the pack to prolong the life of the mesh. I did this on the side pockets as well.
The white material is the 1.9oz ripstop. It will cut the weight down and is used in low wear areas. The mesh is lyrca. The shoulder straps are 4mm spacer mesh and VX21 with 1/4 closed cell foam. The hipbelt is the same, but without the ccf. I added "load stabalizers" (load lifters). They are easily removable as well.
I chose not to use any pad pocket or frame. I use a thermarest z-lite, so I place that in first along the back panel, then place in a compactor bag stuffed with my dry goods. With the loads that I have put in it today, I believe that the zrest transfers weight extremely well for a pad. I can really transfer a lot of the weight into my hip.
Right now, I am interested in this type of compression. It can compress at more points with much less weight. That is the benefit of using light spectra core cord and light d-rings in place of webbing and buckles.
