Compatible with Mountain Buggy Nano?

Hi Vicky, Thank You for your enquiry. Unfortunately we are no longer stockists of Mountain Buggy products, we would recommend you contact them direct as you will need to check if they stock the Nano/Graco Car Seat Adapter. If they do, then yes our Graco Capsule will fit the Nano. We do provide buggy brands ie: Baby Jogger https://www.babyonthemove.co.nz/Baby-Jogger that fit our Graco Capsule if you have no joy with Mountain Buggy. I hope this has helped to answer your query.
