My child, who tends to get hot easily, couldn't use this. It's new and unused. I will compress it for shipping. +++++++ This is a cotton sleeper with a long pile and a double-brushed material. - Features a crotch snap to prevent it from riding up or coming undone. - It has a moderate thickness, is soft to the touch, and is warm. - Made of cotton, so it can be used year-round. - Can be used for babies before they can hold their heads up. - For preventing babies who move around a lot from getting cold while sleeping. - Provides warmth like being wrapped in a blanket, suitable for room wear and cold protection in winter. - Easy to put on and take off with the snap closure.
