For ample car seat bag carrying ability – and then some – check out this cavernous carrier from Rogue Kidz. Sized to take all the major car seat brands or a stroller as well as other baby essentials, this is a super versatile car seat luggage bag. It is durable, and waterproof thanks to its rip-stop nylon outer and will keep your car seat protected and dry and despite its size is actually easy to carry in a range of ways. You get three hand carry straps plus backpack straps if you prefer to go hands free. For extra security you also get a Velcro flap and a top buckle closure. And a great thing about the massive Rogue Kidz convertible car seat travel bag is that it almost disappears into a small fold down pouch when not in use.
