Do miniature versions of pic related exist? Something I can put inside my backpack, enough to hold:
>1L of frozen bottled water
>frozen solid piece(s) of meat
Which will still remain ice cold in ~24 hours? Provided I keep it in favorable conditions.
I like cooking and the places I usually camp in are only accessible by foot, and usually takes ~3 hours of hiking.
There are some places which takes a bit more and I want to go there, but the thought of carrying pic related for more than 3 hours makes me want to kill myself.
