Alpine Muffy baby is designed to protect the extra sensitive hearing of your baby against damaging noise and loud music, for instance at festivals, sports games, fairs, fireworks shows, and races. Muffy baby is recommended for babies and little children up to 36 months of age. The earmuff has a soft, adjustable no-slip headband that does not exert pressure on the fontanelle. Muffy baby is lightweight, prevents over-stimulation due to noise, and helps babies and small children sleep well while travelling.
