Having recently broken my collarbone, the sling provided by the hospital was big and uncomfortable. This product is very comfortable and not bulky at all due to the thin and stretchy material. After worrying that the velcro would lose its stickiness, this was unfounded as the sling stays secure despite me moving about during the day a lot.
I'm a slim build and 5 foot tall, and find this size is just slightly too small. If you are considering buying a sling and you are built like me I would recommend the size up. However, despite this the sling is comfortable and very easy to clean.
