I got a convertible car seat too and thought that it was a pain in the butt when it came to bubs being wrapped - especially in winter. However I've got this gorgeous rug called Snug-as-a-Bug that has a two leg sections like a romper, a hood at the top for the head and then a wrap around there arms. The best part is you can pop them straight into the car seat without unwrapping. Its been a godsend I tell you!! I couldn't say anything about the capsule as I've never even seen one in use!!!
