Start by just looking at every page on McHales website and come up with what you want for a basic design. I would not worry about what fabric is quietest. I would avoid basic cuben fiber though as its loud and crinkly when new. I do not know about the new hybrid cuben as I have never seen it in person. IMO, 500d cordura or dyneema grid is what I would use and I did
. Write down what you are looking for in a pack. Hunting, load hauling, easy access, weight, size, pockets, fabric etc. If you want the biggest and baddest pack from McHale its going to cost you, my bill was over $1,000 for a S-CMII. If I would of went full spectra fabric that price would of shot way up.
