Made for year round use, the fabric is not too heavy for summer and not too thin for winter. The BayB Brand Car Seat Canopy fits all makes and models of infant car seats. Adjustable attachment straps allow for a custom fit. Machine washable, hang dry. Each one of our canopies has bold, fresh, cutting edge prints on 100% cotton outers with soft, snugly, lovable 100% polyester minky interiors. Don't go anywhere without one of these to give your baby the dark, snugly place they deserve while they are in their car seat.
