i fell asleep sitting up and it hit me that a lot of sleeping gear is related to laying down.
i present a new concept: sit camping.
we've all fallen asleep while hunting, right?
so why fon't we just do that on purpose?

get yourself a wearable sitting pad, an army surplus marshmallow suit,
a poncho, and just lean against a tree next time you go to sleep.
this is the perfect ultralight camping setup. wanna leave? just stand up and start walking.
this is also good for innawoods shit because you can immediately react to a threat.
