This is a cover for baby carriers, suitable for winter. It can be used with baby carriers and strollers. The inside is soft to the touch and filled with down, making it very warm. I mainly use a car, so I used it less than 10 times, and there were no leaks or other issues. The retail price was close to 10,000 yen, but I don't plan to use it, so I'm selling it at a bargain price.
