I'm designing a pack for a friend and I need some help choosing main pack body fabric. I'm hoping someone can give me a little insight.
So here are the specs
-32 to 35 liters, IE. large day pack
-must be extremely ruggedly built
-pack will be specifically for geologist/paleontology type field work
-3 liter water bladder + 2 1 liter bottles (does not have to be mounted to sides
-ruck type closure with lid
-sleeve or some sort of mount for crack hammer externally
-2 main compartments one for food/hydration, and one for tool belt respectively
-external sleeve or pocket for metal clip board. (accessible without taking off pack.)
I suggested ballistics or 1k d cordura for pack body. But could something like dynema ripstop do the job as well? He would like to keep the weight down without sacrificing durability.
This will be used in the south west, on field digs.
Any suggestions would be greatly appreciated.
