our main hole was differentiating med supplies as home use vs BOB use. second was was hip straps on GHB/BOBs – somehow it never clicked that carrying around heavy things on our backs without support would be problematic even though all of our day hiking backpacks have at least a thin hip and chest strap. we are looking forward to the coming update! i had guessed that it fell outside of the 80-20 rule for most people. we had been planning to use kitty litter (since we always have at least 10 lbs of it on hand), what are your thoughts on that as the ‘sealed’ layers vs saw dust? we have pump sanitizer and a dedicated camp soap to cover our waste cleansing needs, both human and feline. keep up the great work!
