Cape of Wanderlust (5e Equipment)
From D&D Wiki
Wondrous item, very rare (requires attunement)
This cloak is made of simple unassuming materials, it seems tattered and rough as if it has been on the road for years. While worn in the wilderness it makes it's bearer hard to notice (DC 15 wisdom/perception check).
It can be turned into a small tent on the ground or suspended above the ground. In this form it offers protection from temperatures and rain. It mimics the surroundings so well that creatures must succeed a DC 17 wisdom (perception) test to spot the cloak/tent/hammock.
