The adjustable Velcro straps are designed to cover most carseat that has a handle. But because this canopy doesn't lay flat on the carseat, the best way to know how it fits is to ask other parents who have the same baby carseat that you have.It can also be used as an extra baby blanket, baby carrier cover, carseat blanket, changing pad cover, or worn by a nursing mother as breastfeeding cover or poncho.Is this warm enough for winter?This baby car seat canopy is 0.1 inch thick and has a double layer enough for spring and fall use. If your winters are exceptionally cold, please bundle up your baby with an extra blanket. Please do not leave your child unattended while covered up in the carseat.How will this do on windy walks?Sometimes it blows up but the weight of the fabric along with its Velcro hanger helps not to blow it away. On especially windy days, we recommend tucking the corners of your baby carseat cover into the liner on your car seat.Is this baby cover car seat waterproof?The fabric is water resistant and will keep your baby warm & dry in a light sprinkle. It would absorb water with prolonged exposure, so we don't suggest using this as a means of long-term rain protection.Is it machine washable and dryer-safe?Yes, it holds up well in the washing machine on gentle cycle. Use cold water & mild detergent. No fabric softeners or bleach. Tumble dry on low heat; but if possible, hang to dry.
