Think of the Car Seat Cocoon as a puffy cover for your babys 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 its resistant to both wind and rain, its ultra-lightweight and comfortable for your little one. Its a timesaver, too. You wont 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 babys head. The Cocoon has an ultra-soft insulation, plush lining and best of all, its totally machine washable and dryable. *color of grey shell changes depending on light!
