Abstract: The present disclosure describes a temperature controlled bag comprising an unpowered cooling device and a bag. The bag includes an insulated chamber defining a cavity to be cooled, a protective layer exterior to the insulated chamber, and an outer fabric shell. A strap is utilized to secure the cooling device in place with a sealing amount of pressure to engage a gasket, ensuring efficient cooling performance. The innovative design of this temperature controlled bag provides effective cooling capabilities while maintaining a compact and portable structure, making it ideal for various cooling applications. Also disclosed is an absorptive cooling device which may include a reservoir configured to contain a fluid. The device may further include an evaporator adjacent to an object to be cooled and an adsorber including a metal-organic framework adsorbent, wherein the device is not connected to a power source. Methods of cooling an object using the device are also described.
