The J.L. Childress Elite Padded Travel Bag is designed for an Infant Car Seat and Stroller Combo, such as the Doona (fits BOTH seat AND base). The Elite also fits most other infant car seats and bases, and fits the Evenflo Shyft DualRide SEAT ONLY. Please measure your car seat before purchasing this item to ensure compatibility. The Elite Padded Travel Bag has thick padding and durable, premium materials to properly protect your infant car seat and stroller combo. Padded, adjustable backpack straps ensure comfortable, hands-free carrying. The Elite uniquely attaches to a stroller handlebar with built-in buckle straps to easily transport through the airport. Scratch-resistant material has been added to the bottom of the bag for extra protection. The bright red Gate Check tag can be used if gate checking your gear for added visibility. A discreet silicone AirTag holder is attached to the interior of the bag, allowing you to insert your own AirTag and track your valuable car seat and stroller combo. Backpack straps detach and tuck away during transit to avoid damage. The dual zipper, large opening makes it easy to take your gear in and out of the bag, and can be locked for added security. Use the top carry handle to easily lift your bag and the clear ID pocket and ID card to identify your bag. The Elite Padded Travel Bag is backed by our Lifetime Warranty and U.S. based Customer Service Team. Travel Happy with J.L. Childress!
