The Dead Lands of Athas
Dustcloak of Desert Travel
A creature wearing this cloak suffers no harm from being in a hot or cold environment. It can exist comfortably in all natural conditions found on Athas, including the Obsidian Plains and the Ring of Fire, without having to make Fortitude saves. The wearer’s equipment is likewise protected. Wearing this cloak negates the penalty to Fortitude saves versus heat from wearing armor. A wastelander’s cloak doesn’t provide any protection from fire or cold damage, nor does it protect against other environmental hazards such as smoke, lack of air, and so forth.
