My hammock can serve as a tarp as well
Crocs for a 2nd pair of shoes to get your feet out of your hiking boots for a bit
Spork for eating utensil does everything a fork and spoon would
Empty food pouches to store other garbage in to keep the scent down
and I am going to now use my pack cover for gear storage after seeing that suggested here.
In the depths of winter I finally learned there was in me an invincible summer. [Albert Camus]
