The stroller bag is great quality and a nice addition to keep the car seat clean and easier to travel.
Bag seems very high quality, but the zipper broke on the return flight of our first trip. Lost the attachments that were in the bag but thankfully nothing else. Seems like uppababy will replace, but make sure you secure it two ways to prevent this from happening
I bought this travel bag for the mesa car seat because I already own the travel bag for my vista. We have a trip coming up and I've been nervous about protecting our stroller and car seat during the flight.
Nuna doesn't make a car seat bag for some reason, but this worked great for my Nuna Pipa.
