Does Nina do a bag just like this for the Nuna ARRA Next capsule and base? Or would this fit an Arra?

Hi Craig, the Nuna PIPA Series Travel Bag will fit an ARRA capsule but not the ARRA capsule and base. If you are looking for a Nuna bag that fits both, I would suggest the Nuna Wheeled Transport Bag. Here is a link to it here: https://www.babyonthemove.co.nz/products/on-the-move/single-buggies/travel-bags/nuna-wheeled-travel-bag/. Hope that helps
