I LOVE Rylie's Sturdibag and so does she. She goes in it voluntarily and sleeps in it at night.
The thing about my Sturdibag is that it meets all the requirements people were talking about (ventilation, a securing measure, full zippers, pockets, good straps, etc.), but it also has this really awesome comfy washable pad for Rylie! It is super soft and machine washable and is really great imo compared to the other cruddy carrier bottoms out there. I know she's comfy and safe in her Sturdibag and that makes me very happy!
In addition, it has a seat belt track for the car to secure it in and has a flexible top, which I like.
I could go on and on, but I highly recommend the Sturdibag!
