Hi, would this fit a maxi cosi pria or cosco scenera?

Hi Hayley, thank you for your enquiry, the Britax Travel Bag is suitable for most Britax Carseats, not capsules so we couldn’t guarantee a good fit. We would suggest talking to your local store in regards to this as there maybe other options. We hope this helps. ?For further information on this or any of our other products available, if you follow the link https://www.babyonthemove.co.nz/store-locations/ this will take you to our online store finder.
