|Designed by an Ear Nose and Throat doctor to help his young patients keep their silicone ear plugs in place while swimming and playing in water, these terrific neoprene headbands are ideal. We recommend them especially for very young children because they can help prevent choking on plugs that accidentally fall out. Available in three sizes and five colors. Velcro fastener. Note: Neoprene headbands may need to be stretched by hand a bit in order to achieve a comfortable fit.
