Car seat covers keep babies warm while riding in a carseat or stroller. They have a fuzzy inner layer and a protective outer layer. They can be zipped or unzipped to let you control the temperature. They fit securely around the seat and can easily be used as a replacement for blankets. They are also machine washable for easy cleaning. They come in a variety of styles, colors, and sizes.

JJ Cole’s bundle me covers are made from weather-resistant nylon and soft fleece. They have an elastic design that is simple to secure over infant carriers and standard strollers for a custom fit. The blanket-like design eliminates the need for bulky coats and allows your baby’s safety straps to rest directly on their chest. They can be zipped or unzipped for easier access and are machine washable.

However, like other aftermarket products, the JJ Cole bundle me original and urban and the Britax bundled me tri-stitch can cause voiding of your car seat’s warranty as they are not exclusively produced by your car seat manufacturer and may interfere with proper harness positioning. They are also unsafe to use while your infant is in a moving vehicle as they allow too much space between your child’s back and the car seat back or between their chest and the harness straps.

Other car seat covers, like the Cozy Cover and Jolly Jumper Arctic Sneak a Peak, are safer as they don’t interfere with the harness position or feature a front flap. They also don’t offer the weather-resistant outer shell or the faux shearling of the JJ Cole bundle me covers.
