The bundle bean stroller cozy is a rectangular type blanket approximately 38" x 24". it is a flannel type plush on one side and a weatherproof nylon on the other. There is a 16" zipper on each side and when zipped the cozy forms a pouch at the bottom to tuck around the feet (see photo). There are tabs at the top to hook onto the stroller to hold it in place. This is fabulous, no more trying to keep your toddler covered, no more blanket on the floor or caught in the wheels. Your toddler is not restricted, they can move their feet inside the pouch without dislodging everything. There is a pocket on the front for treasures or warm hands. you're going to love this!!!
