I know Americans catch a lot of flag online but man, I'm jealous of your guys' nature. Best we have are some shitty little patches of forest where you have to stealth camp since it's probably owned by some asshole farmer
Here in Australia, Swags are the go-to camping solution for solo camping, and also couple touring.
A Swag is a local type of Bivouac sack that could just be anything from a blanket wrapped in a tarp, upto a custom canvas tent-like structure that can be quickly rolled out, with integrated mattress and separate stretcher.
A few of the lighter-weight ones have an opening on the topside where you can leave them open for stargazing on dry nights.
There are also hammock swags with insulation above and below.
