I read lots of reviews in several different bag about how these are all cheap and only lasted one way on a flight so I decided to get the cheapest bags I could find (which were these) and see what happens. I got the two pack in red. When they arrived I turned them inside out and duct taped all the seams and added extra support around the middle. These two bags went from kc to philly and philly to kc and all we have on one bag is a small tiny hole smaller than a dime! I believe by giving the seams extra support with the tape helped tremendously and these can be used for several flights! Buy these and just add some tape and you will be good! No need to spend tons of money on the other bags that are exactly the same!This is perfect for the high back booster I am bringing to Disney. I could easily fit more in the bag if neededReason for 4 stars is because it held up better than I thought it would for how cheap this was compared to others. I have a small rip in it on the bottom after our carseat was gate checked. We brought our graco 4ever dlx carseat which is very heavy and it barely fit in the bag it probably has about a 3inch hole when you pull the string tight. I think if we had a lighter carseat we may not of had a rip in the bag.Our baby’s Graco Convertible carseat fitted perfectly and it hold up great throughout MCO, twice! It did not break, loosen nor stain. It is easily foldable and fits in the suitcase or backpack until needed. It has a strap that allows to secure it tight so it wont open. The material is great and the color helped us identify it quickly. Recommended.We used this for my daughters car seat for a round trip flight and I’m glad we had it! While it wasn’t required it made it easier to carry the seat an protect it as I saw some black smudges on the bag itself, I’m very glad I had a bag to get smudged instead of them getting the car seat itself dirty. It may have been nice to have an extra strap to put the car seat around my shoulder to carry it like a purse, or even a backpack. But I’m really happy with this purchase!This was a pretty ok product it’s really for one use only. I traveled overseas and it kept the car seat clean but the bag was pretty beat up. I probably would need to get a new one for the next trip.Went to pick up the car seat at the airport and the bag was dirty but the car seat was not and that’s what mattersFit well, traveled pretty good. Protected the car seat but definitely cheap material…it might last one more trip before it tears. You get what you pay for
