Think of the Car Seat Cocoon as a puffy cover for your baby's car seat! It fits all models seamlessly, slipping on and off in seconds and fitting snugly thanks to a simply designed elastic base. And though it's resistant to both wind and rain, it's ultra-lightweight and comfortable for your little one. It's a timesaver, too. You won't have to struggle with multiple layers of garments, just make sure your baby is well dressed in the car seat and the Car Seat Cocoon will shield from the harshest conditions, keeping baby cozy on winter walks. If it gets a little too warm outside or in the car, just pop open the convenient side shoulder zippers to uncover baby's head. The Cocoon has an ultra-soft insulation, micro-fleece, plush or cloud lining and best of all, it's totally machine washable and dryable.
