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.
