I have an 35 l (I don't know how many cubic inches it comes) Snugpak Sleeka Force backpack, is my primary daypack, so I'll make an experiment for how much gear will come in it. Until now I had 3 days' worth of gear, food was 2 CR1M australian rations I had from Yowie and one "new model" EPa. Because here already came the fall and I can't go camping as in the summer, I'll leave to next year spring. I'll make some comparations between size vs. nutritional value and variety.Treesuit wrote: Unfortunately a new questions comes to mind and that is, could the camelbak tri zip function more in the way of just a three day pack? How about 5 or 6 days?
I had to say, IMHO, the most compact rations are the CR1M, the "new model" EPa and your prototypes.
