Please refrain from purchasing if you are nervous. No returns. I tried it on once at home after opening it, but I didn't use it and stored it. I washed it once for the purpose of listing it. It has four buttons, so you can adjust it when you wrap it around your waist. It's made of nylon fabric with cotton filling, so I think it will be warm. I think it can also be folded and used as a cushion. I will compress the packaging, so please understand. Length: Approximately 60cm, Width: Approximately 118cm Measurements are approximate as they are taken by a layman.
