Best in design and rich in appeal, this green and pink coloured ear cover from Bizarro is sure to make your little champ look the best amidst his pals. Acrylic wool is very easy to care for. It is a stain resistant fabric and will not irritate the skin of your kid. Acrylic is a lot lighter than wool which makes it a great fabric for the young kids. When machine washing, use warm water and add a fabric softener during the final rinse cycle.
