This Maxi Cosi Travel Carseat bag is great! The material is super durable, much more so than those bright red gate check bags - you know the ones, inexpensive and lucky to last a single trip? The seams on this are reinforced, the shoulder straps are padded, and the design is simple and sleek. The straps fold up and tuck away nicely when not in use, but can be quickly removed and buckled into place. We use it with our Pria All-In-One Convertible seat, affectionately known as "the rocket ship". The seat is huge, but so comfortable and safe that we come back to it every time (we have 4 kids). Lugging that thing around for travel is no small feat though. Carrying it by the straps is heavy and difficult, especially when trying to maneuver with small kids or other luggage. This bag not only fit the seat perfectly (almost like it was specifically designed for that), but made handling much more manageable. The wheels are very convenient, but I cannot speak to how they would hold up being tossed around with checked airline luggage. In addition to backpack straps, there is a handle on top and one on the side for easy lifting. The bag folds up and would easily fit in an airline overhead bin if it was used to get a carseat onto a plane for travel. When folded, it also easily fits in a large suitcase or duffel, or would slide under a bed, so it doesn't take up much room while on the road. It's still a bulky seat, don't get me wrong, but when you want to travel safely with littles, you do what you gotta do! Honestly, the Maxi-Cosi seats are already a bit pricier than other options on the market, so do you really want to stress about that investment? This high quality bag can provide ease of mind and let you focus on the fun part - traveling with your kids! Thanks to the Stellar Product Testing Panel for giving me a chance to try out this bag!
