"This is my favorite thing to buy for friends who are expecting. In a town like Chicago, the weather can change at a moment's notice, and you don;t want to constatly have to peel layers off your baby as things go from windy and cold to bright and sunny. The bundle me is a great way to keep your baby warm in the carseat without the bulkiness of coats and sweaters that get in the way of being able to safely buckle him/her into the seat. This is an ESSENTIAL item for any new parent!It unzips easily to pop baby in and out, and is adjustable as just a foot cover to being all the way up to the baby's chin (or over, for really windy days!). We had both the original (shown here) and a lighter urban bundle me for fall/spring, that was more "windbreaker" weight. Great product!"
