J.L. Childress Ultimate Padded Backpack Car Seat Travel Bag - Thick Padding, Heavy Duty Backpack, AirTag Holder - Gate Check Bag Fits All Car Seats & Boosters - Black

Travelled international with this and it worked perfect. Love the straps - do not get one without the backpack straps, I don’t know how people manage with their baby and all their gear without wearing the car seat on their back. No damage after 12+ hours of travelling one way (and then also return). Used on 4 flights total for our trip. Fits the nuna pipa car seat perfect (with the roll bar in the up position). Excellent for the price would definitely buy again. For comparison we bought the doona padded stroller cover for our nuna stroller and while it did protect the stroller well and found it easy to use , the stitching ripped on the shoulder strap after the first 3hr leg of our trip (the bag cost $100 compared to this cheap unpadded one)

Nice and big but after 1 flight it was ripped on the bottom where it has been moved by staff at the airport The material could be stronger

This bag is a snug fit for our Britax B-First Clicktight Convertable car seat, the only one that we could find big enough without being ridiculously huge. It had minimal passing but it must be better than not using a cover.

This fit my nuna pipa car seat perfectly and I had enough room to squeeze in a pack of diapers 🤭and few small baby blankets

Great car seat bag! I was able to fit a convertible seat with an infant seat inside. No damage averted several flights.
