I purchased this in July 2024, but I haven't had a chance to use it, so I'm putting it up for sale. This is the 450ml model. How about lightening your gear? Here are the specifications: The STAND COZY is a self-supporting cozy bag for rehydrating a single-serving Ziploc-sized bag of food. It uses Astrofoil, which has high insulation performance, allowing for efficient heat retention. The exterior uses durable and self-supporting materials such as X-PAC, hard Tyvek, and Cuben DCF, so it remains stable even when placed on the ground and can be used for a long time. Using the STAND COZY is easy. Simply set the bagged dry food inside and pour in hot water. It stands up firmly, so there's no need to worry about it tipping over. Close the mouth of the Ziploc bag after removing the air, fold it over, and store it in the STAND COZY to keep it warm. Also, if you rehydrate food with water while hiking, the cozy protects it, reducing leaks inside your backpack. You can also hold the STAND COZY with the rehydrated bagged meal inside and eat it. It's designed with attention to detail, such as a thickness that's easy to hold with one hand, ease of use with a spoon, and a design that allows you to fold the mouth of a Ziploc M-size bag outward. Furthermore, if you put your finger through the shock cord that serves as a handle, you don't have to worry about it flipping over if you accidentally drop it. When you take your hands off during a meal, it stands up on its own, so you can place it on the ground. If you close the mouth, you can keep your meal warm for a while. Also, because it covers the transparent Ziploc bag, you don't have to worry about others seeing the contents. Holding the STAND COZY There's a finger loop, so you don't have to worry about it slipping out of your hand. The STAND COZY can be folded flat for storage and can also be used as a small item pouch. Thanks to the insulation protection material, you can safely pack metal products such as cutlery and alcohol stoves, as well as electrical devices such as smartphones and batteries. The body weight is only 17g, making it very lightweight and won't add any burden to your usual packing.
