This is one of the various cozies I purchased and used for tent-camping mountain climbing, serving as both a cozy for meals and a storage cover for a Jetboil. This is the old model with a capacity of 450ml. Although it had high heat retention, it was too small to store a Jetboil, so I'm letting it go. The alpha rice in the photo is not included. It's in good condition with little wear and tear. How about it for warm meals during mountain climbing, hiking, camping, etc. in the coming season? From the following site: The STAND COZY is a self-supporting cozy bag for rehydrating a single serving of food in a Ziploc-sized bag. 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 can be placed on the ground stably and used for a long time. Using the STAND COZY is easy. Simply set the bagged dry food and pour hot water directly into it. It stands firmly, so there's no need to worry about it falling over. Close the mouth of the Ziploc bag after removing the air, fold it in, and store it in the STAND COZY to keep it warm. Also, even when rehydrating with water while hiking, the cozy protects the bag, reducing leaks inside the backpack. You can also hold the STAND COZY in your hand while eating the bag of rice rehydrated with hot water. It's designed with attention to detail, such as a thickness that's easy to hold in 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 on its own, so you can place it on the ground. By closing the mouth, you can keep the meal warm for a while. Also, because it covers the transparent Ziploc, you don't have to worry about others seeing the contents. Holding the STAND COZY in your hand There's a finger loop for peace of mind in case your hand slips. The STAND COZY can be folded flat for storage and can also be used as a small 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 main body weighs only 17g, making it very lightweight and not a burden to add to your usual packing.
