Thanks for the comments.
With today really light fabric and other light material, gear can be make much lighter than a few years ago.
I am working on a small pack for my Sub 2-lb load and it is going to be really light. I don't want to speculate yet but I think less than 1 ounce. It will be made out of Cuben fiber, what else. The total pack weight at the start of day one should be around 8 pounds with 1 liter of water.
I am still under my 32 ounce mark by 7.88 oz. When I add everything I need If I have 5.61 oz left I want to add my gravity water filter.
